{{Short description|Standard that is openly accessible and usable by anyone}}
An '''open standard''' is a standard that is openly accessible and usable by anyone. It is also a common prerequisite that open standards use an open license that provides for extensibility. Typically, anybody can participate in their development due to their inherently open nature. There is no single definition, and interpretations vary with usage. Examples of open standards include the [[GSM]], [[4G]], and [[5G]] standards that allow most modern [[mobile phone]]s to work world-wide.

== Definitions ==
The terms ''open'' and ''standard'' have a wide range of meanings associated with their usage. There are a number of definitions of open standards which emphasize different aspects of openness, including the openness of the resulting specification, the openness of the drafting process, and the ownership of rights in the standard. The term "standard" is sometimes restricted to technologies approved by formalized committees that are open to participation by all interested parties and operate on a consensus basis.

The definitions of the term ''open standard'' used by academics, the [[European Union]], and some of its member governments or parliaments such as [[Denmark]], [[France]], and [[Spain]] preclude open standards requiring fees for use, as do the [[New Zealand]], [[South Africa]]n and the [[Venezuelan]] governments. On the standard organisation side, the [[World Wide Web Consortium]] (W3C) ensures that its specifications can be implemented on a [[royalty-free]] basis.

Many definitions of the term ''standard'' permit [[patent holder]]s to impose "[[reasonable and non-discriminatory]] licensing" [[royalty fee]]s and other licensing terms on implementers or users of the standard. For example, the rules for standards published by the major internationally recognized standards bodies such as the [[Internet Engineering Task Force]] (IETF), [[International Organization for Standardization]] (ISO), [[International Electrotechnical Commission]] (IEC), and [[ITU-T]] permit their standards to contain specifications whose implementation will require payment of patent licensing fees. Among these organizations, only the IETF and ITU-T explicitly refer to their standards as "open standards", while the others refer only to producing "standards". The IETF and ITU-T use definitions of "open standard" that allow "reasonable and non-discriminatory" patent licensing fee requirements.

There are those in the open-source software community who hold that an "open standard" is only open if it can be freely adopted, implemented and extended.<ref name="book">{{cite web |first1=Henry William | last1= Chesbrough |first2= Wim | last2= Vanhaverbeke|first3= Joel | last3= West |title=Tim Simcoe: 'Chapter 8: Open Standards and Intellectual Property Rights' in Open Innovation: Researching A New Paradigm | publisher= Oxford University Press | url=https://www.researchgate.net/publication/232957368 |year =2008|access-date= April 25, 2017}}</ref> While open standards or architectures are considered non-proprietary in the sense that the standard is either unowned or owned by a collective body, it can still be publicly shared and not tightly guarded.<ref name="Langlois, Richard N 1999">Langlois, Richard N.

''Standards and Public Policy''. Cambridge, UK: Cambridge University Press, 2007.</ref>

Open standards which specify formats are sometimes referred to as [[open format]]s.

Many specifications that are sometimes referred to as standards are proprietary, and only available (if they can be obtained at all) under restrictive contract terms from the organization that owns the [[copyright]] on the specification. As such these specifications are not considered to be fully ''open''. Joel West has argued that "open" standards are not black and white but have many different levels of "openness".<ref>{{Citation |last=West |first=Joel |title=The economic realities of open standards: black, white, and many shades of gray |date=2006-12-21 |url=https://www.cambridge.org/core/product/identifier/CBO9780511493249A012/type/book_part |work=Standards and Public Policy |pages=87–122 |editor-last=Greenstein |editor-first=Shane |access-date=2023-06-29 |edition=1 |publisher=Cambridge University Press |doi=10.1017/cbo9780511493249.004 |isbn=978-0-521-86450-3 |s2cid=17934389 |editor2-last=Stango |editor2-first=Victor|url-access=subscription }}</ref> A more open standard tends to occur when the knowledge of the technology becomes dispersed enough that competition is increased and others are able to start copying the technology as they implement it.

== Specific definitions of an open standard ==

=== Made by standardization bodies ===

==== Joint IEEE, ISOC, W3C, IETF and IAB Definition ====
On August 12, 2012, the [[Institute of Electrical and Electronics Engineers]] (IEEE), [[Internet Society]] (ISOC), [[World Wide Web Consortium]] (W3C), [[Internet Engineering Task Force]] (IETF) and [[Internet Architecture Board]] (IAB), jointly affirmed a set of principles which have contributed to the [[exponential growth]] of the Internet and related technologies. The "OpenStand Principles" define open standards and establish the building blocks for innovation.<ref>{{Cite web|url=https://open-stand.org/about-us/affirmation/|title=Affirmation Statement|website=OpenStand|language=en-US|access-date=2019-07-17}}</ref><ref>{{Cite web|url=https://open-stand.org/about-us/principles/|title=The Modern Standards Paradigm – Five Key Principles|website=OpenStand|language=en-US|access-date=2019-07-17}}</ref> Standards developed using the OpenStand Principles are developed through an open, participatory process, support interoperability, foster global competition, are voluntarily adopted on a global level and serve as building blocks for products and services targeted to meet the needs of markets and consumers. This drives innovation which, in turn, contributes to the creation of new markets and the growth and expansion of existing markets.

{{anchor|Principles}}There are five key '''OpenStand Principles''', as outlined below:<ref>Open Stand, [https://open-stand.org/infographic-the-5-core-principles-of-openstand/ Infographic: The 5 Core Principles of OpenStand], accessed on 23 August 2025</ref>

'''1. Cooperation'''
Respectful cooperation between standards organizations, whereby each respects the autonomy, integrity, processes, and intellectual property rules of the others.

'''2. Adherence to Principles''' – Adherence to the five fundamental principles of standards development, namely

*'''''Due process:''''' Decisions are made with equity and fairness among participants. No one party dominates or guides standards development. Standards processes are transparent and opportunities exist to appeal decisions. Processes for periodic standards review and updating are well defined.
*'''''Broad consensus:''''' Processes allow for all views to be considered and addressed, such that agreement can be found across a range of interests.
*'''''Transparency:''''' Standards organizations provide advance public notice of proposed standards development activities, the scope of work to be undertaken, and conditions for participation. Easily accessible records of decisions and the materials used in reaching those decisions are provided. Public comment periods are provided before final standards approval and adoption.
*'''''Balance:''''' Standards activities are not exclusively dominated by any particular person, company or interest group.
*'''''Openness:''''' Standards processes are open to all interested and informed parties.

'''3. Collective Empowerment'''
Commitment by affirming standards organizations and their participants to collective [[empowerment]] by striving for standards that:

* are chosen and defined based on technical merit, as judged by the contributed expertise of each participant;
* provide global interoperability, scalability, stability, and resiliency;
* enable global competition;
* serve as building blocks for further innovation; and
* contribute to the creation of global communities, benefiting humanity.

'''4. Availability'''
Standards specifications are made accessible to all for implementation and deployment. Affirming standards organizations have defined procedures to develop specifications that can be implemented under fair terms. Given market diversity, fair terms may vary from royalty-free to [[fair, reasonable, and non-discriminatory]] terms (FRAND).

'''5. Voluntary Adoption'''
Standards are voluntarily adopted and success is determined by the market.

==== ITU-T definition ====
The [[ITU-T]] is a [[standards development organization]] (SDO) that is one of the three sectors of the [[International Telecommunication Union]] (a specialized agency of the [[United Nations]]). The ITU-T has a Telecommunication Standardization Bureau director's ''Ad Hoc'' group on IPR that produced the following definition in March 2005, which the ITU-T as a whole has endorsed for its purposes since November 2005:<ref>{{cite web|url=http://www.itu.int/ITU-T/othergroups/ipr-adhoc/openstandards.html|title=ITU-T|website=www.itu.int|access-date=18 March 2018}}</ref>
: The [[ITU-T]] has a long history of open standards development. However, recently some different external sources have attempted to define the term "Open Standard" in a variety of different ways. In order to avoid confusion, the ITU-T uses for its purpose the term "Open Standards" per the following definition:
: "Open Standards" are standards made available to the general public and are developed (or approved) and maintained via a collaborative and consensus driven process. "Open Standards" facilitate [[interoperability]] and data exchange among different products or services and are intended for widespread adoption.
: Other elements of "Open Standards" include, but are not limited to:
:*Collaborative process – voluntary and market driven development (or approval) following a transparent consensus driven process that is reasonably open to all interested parties.
:* Reasonably balanced – ensures that the process is not dominated by any one interest group.
:* Due process – includes consideration of and response to comments by interested parties.
:* [[Intellectual property rights]] (IPRs) – IPRs essential to implement the standard to be licensed to all applicants on a worldwide, non-discriminatory basis, either (1) for free and under other reasonable terms and conditions or (2) on reasonable terms and conditions (which may include monetary compensation). Negotiations are left to the parties concerned and are performed outside the [[standards organization|SDO]].
:* Quality and level of detail – sufficient to permit the development of a variety of competing implementations of interoperable products or services. Standardized interfaces are not hidden, or controlled other than by the SDO promulgating the standard.
:* Publicly available – easily available for implementation and use, at a reasonable price. Publication of the text of a standard by others is permitted only with the prior approval of the SDO.
:* On-going support – maintained and supported over a long period of time.

The [[ITU-T]], [[ITU-R]], [[ISO]], and [[IEC]] have harmonized on a common patent policy <ref>{{cite web|url=http://www.itu.int/ITU-T/ipr/|title=ITU-T|website=www.itu.int|access-date=18 March 2018}}</ref> under the banner of the [[World Standards Cooperation|WSC]]. However, the ITU-T definition should not necessarily be considered also applicable in ITU-R, ISO and IEC contexts, since the Common Patent Policy 
<ref>{{cite web|url=http://isotc.iso.org/livelink/livelink/fetch/2000/2122/3770791/customview.html?func=ll&objId=3770791&objAction=browse&sort=name|title=00. ISO standards and patents|website=isotc.iso.org|access-date=18 March 2018}}</ref> does not make any reference to "open standards" but rather only to "standards".

==== IETF definition ====
In section 7 of its RFC 2026, the [[IETF]] classifies specifications that have been developed in a manner similar to that of the IETF itself as being "open standards," and lists the standards produced by [[ANSI]], [[ISO]], [[IEEE]], and [[ITU-T]] as examples. As the IETF standardization processes and IPR policies have the characteristics listed above by ITU-T, the IETF standards fulfill the ITU-T definition of "open standards".

However, the IETF has not adopted a specific definition of "open standard"; both RFC 2026 and the IETF's mission statement (RFC 3935) talks about "open process", but RFC 2026 does not define "open standard" except for the purpose of defining what documents IETF standards can link to.

RFC 2026 belongs to a set of RFCs collectively known as BCP 9 (Best Common Practice, an IETF policy).<ref>[http://tools.ietf.org/html/bcp9 BCP 9]: The Internet Standards Process</ref> RFC 2026 was later updated by BCP 78 and 79 (among others). As of 2011 BCP 78 is RFC 5378 (Rights Contributors Provide to the IETF Trust),<ref>[http://tools.ietf.org/html/bcp78 BCP 78]: Rights Contributors Provide to the IETF Trust</ref> and BCP 79 consists of RFC 3979 (Intellectual Property Rights in IETF Technology) and a clarification in RFC 4879.<ref>[http://tools.ietf.org/html/bcp79 BCP 79]: Intellectual Property Rights in IETF Technology</ref> The changes are intended to be compatible with the "Simplified [[BSD]] License" as stated in the IETF Trust Legal Provisions and Copyright FAQ based on RFC 5377.<ref>[[IETF]] [http://trustee.ietf.org/license-info Trust Legal Provisions] (page offers a FAQ for non-lawyers)</ref>

In August 2012, the IETF combined with the W3C and [[IEEE]] to launch OpenStand <ref name="OpenStand">[http://open-stand.org OpenStand]: OpenStand: Principles for The Modern Standard Paradigm</ref> and to publish The Modern Paradigm for Standards. This captures "the effective and efficient standardization processes that have made the Internet and Web the premiere platforms for innovation and borderless commerce". The declaration is then published in the form of RFC 6852 in January 2013.

=== By legislative or governmental bodies ===

==== European Interoperability Framework for Pan-European eGovernment Services ====
The [[European Union]] defined the term for use within its European Interoperability Framework for Pan-European eGovernment Services, Version 1.0<ref>[http://ec.europa.eu/idabc/servlets/Docd552.pdf?id=19529 European Interoperability Framework for pan-European eGovernment Services], Version 1.0 (2004) {{ISBN|92-894-8389-X}} page 9</ref> although it does not claim to be a universal definition for all [[European Union]] use and documentation.

<blockquote>
To reach interoperability in the context of pan-European eGovernment services, guidance needs to focus on open standards.
</blockquote>

The word "open" is here meant in the sense of fulfilling the following requirements:
<blockquote>
* The standard is adopted and will be maintained by a not-for-profit organization, and its ongoing development occurs on the basis of an open decision-making procedure available to all interested parties (consensus or majority decision etc.).
* The standard has been published and the standard specification document is available either freely or at a nominal charge. It must be permissible to all to copy, distribute and use it for no fee or at a nominal fee.
* The intellectual property – i.e. patents possibly present – of (parts of) the standard is made irrevocably available on a [[royalty-free]] basis.
* There are no constraints on the re-use of the standard<ref>{{citation |url=http://ec.europa.eu/idabc/servlets/Docd552.pdf?id=19529 |format=PDF |title=European Interoperability Framework for pan-European eGovernment Services |author=European Communities |year=2004 |access-date=2016-02-09}}</ref>
</blockquote>

==== Network Centric Operations Industry Consortium definition ====
The [[Network Centric Operations Industry Consortium]] (NCOIC) defines open standard as the following:
<blockquote>Specifications for hardware and/or software that are publicly available implying that multiple vendors can compete directly based on the features and performance of their products. It also implies that the existing open system can be removed and replaced with that of another vendor with minimal effort and without major interruption.<ref>{{usurped|1=[https://web.archive.org/web/20051230055753/http://www.ncoic.org/home Network Centric Operations Industry Consortium]}}, {{citation |url=http://wiki.ncoic.net/index.php?title=Open_Standards |title=NCOIC Lexicon |access-date=2013-12-31 |archive-date=2014-01-01 |archive-url=https://web.archive.org/web/20140101162437/http://wiki.ncoic.net/index.php?title=Open_Standards |url-status=dead }}, 2008</ref>
</blockquote>

==== Danish government definition ====
The [[Danish government]] has attempted to make a definition of open standards,<ref>{{cite web|url=http://www.itst.dk/it-arkitektur-og-standarder/standardisering/Tekniske-standarder/arkiv/oio-kataloget-arkiv-version/Definition_of_open_standards.pdf|title="Definitions of Open Standards", 2004|website=itst.dk|access-date=18 March 2018}}</ref> 
which also is used in pan-European software development projects. It states:

<blockquote>
* An open standard is accessible to everyone free of charge (i.e. there is no discrimination between users, and no payment or other considerations are required as a condition of use of the standard)
* An open standard of necessity remains accessible and free of charge (i.e. owners renounce their options, if indeed such exist, to limit access to the standard at a later date, for example, by committing themselves to openness during the remainder of a possible patent's life)
*An open standard is accessible free of charge and documented in all its details (i.e. all aspects of the standard are transparent and documented, and both access to and use of the documentation is free)
</blockquote>

==== French law definition ====
The [[French Parliament]] approved a definition of "open standard" in its ''Loi n° 2004-575 du 21 juin 2004 pour la confiance dans l'économie numérique'' ("Law for Confidence in the Digital Economy").<ref>{{cite web|url=https://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000000801164&dateTexte=&categorieLien=id|title="Loi n° 2004-575 du 21 juin 2004 pour la confiance dans l'économie numérique|website=legifrance.gouv.fr|lang=fr|access-date=3 September 2025}}</ref> The definition is (Article 4):

<blockquote>
* By open standard is understood any communication, interconnection or interchange protocol, and any interoperable data format whose specifications are public and without any restriction in their access or implementation.
</blockquote>

==== Indian Government definition ====
A clear [[royalty-free]] stance and far reaching requirements case is the one for [[India's Government]]<ref name="Policy in India">{{cite web|last1=Government of India|title=Policy on Open Standards for e-Governance|url=https://egovstandards.gov.in/sites/default/files/Published_Policy_Framework_Document/Policy%20on%20Open%20Standards%20for%20e-Governance.pdf|access-date=25 July 2014|ref=india|archive-date=29 July 2014|archive-url=https://web.archive.org/web/20140729104207/https://egovstandards.gov.in/sites/default/files/Published_Policy_Framework_Document/Policy%20on%20Open%20Standards%20for%20e-Governance.pdf|url-status=dead}}</ref>

<blockquote>
'''4.1 Mandatory Characteristics'''
An Identified Standard will qualify as an "Open Standard", if it meets the following criteria:
*4.1.1 Specification document of the Identified Standard shall be available with or without a nominal fee.
* 4.1.2 The Patent claims necessary to implement the Identified Standard shall be made available on a Royalty-Free basis for the lifetime of the Standard.
* 4.1.3 Identified Standard shall be adopted and maintained by a not-for-profit organization, wherein all stakeholders can opt to participate in a transparent, collaborative and consensual manner.
* 4.1.4 Identified Standard shall be recursively open as far as possible.
* 4.1.5 Identified Standard shall have technology-neutral specification.
* 4.1.6 Identified Standard shall be capable of localization support, where applicable, for all Indian official Languages for all applicable domains.
</blockquote>

==== Italian Law definition ====

Italy has a general rule for the entire public sector dealing with Open Standards, although concentrating on data formats, in Art. 68 of the Code of the Digital Administration (''Codice dell'Amministrazione Digitale'')<ref>{{cite web|title=Art. 68 CAD|url=http://www.normattiva.it/uri-res/N2Ls?urn:nir:stato:decreto.legislativo:2005-03-07;82!vig=|access-date=25 July 2014}}</ref>

<blockquote>

[applications must] allow representation of data under different formats, at least one being an open data format.

[...]

[it is defined] an open data format, a data format which is made public, is thoroughly documented and neutral with regard to the technological tools needed to peruse the same data.
</blockquote>

==== New Zealand official interoperability framework definition ====
The [[E-Government Interoperability Framework]] (e-GIF) <ref>{{cite web|url=http://www.e.govt.nz/standards/e-gif/e-gif-v-3-1/policy/e-gif-v-3-1-policy.pdf|title="New Zealand E-Government Interoperability Framework (e-GIF)" version 3.0, June, 22nd 2007|website=e.govt.nz|access-date=18 March 2018|archive-date=16 October 2008|archive-url=https://web.archive.org/web/20081016002645/http://www.e.govt.nz/standards/e-gif/e-gif-v-3-1/policy/e-gif-v-3-1-policy.pdf|url-status=dead}}</ref> defines open standard as royalty-free according to the following text:

<blockquote>
While a universally agreed definition of "open standards" is unlikely to be
resolved in the near future, the e-GIF accepts that a definition of "open standards"
needs to recognise a continuum that ranges from closed to open, and encompasses
varying degrees of "openness." To guide readers in this respect, the e-GIF
endorses "open standards" that exhibit the following properties:

* Be accessible to everyone free of charge: no discrimination between users, and no payment or other considerations should be required as a condition to use the standard.
* Remain accessible to everyone free of charge: owners should renounce their options, if any, to limit access to the standard at a later date.
* Be documented in all its details: all aspects of the standard should be transparent and documented, and both access to and use of the documentation should be free.

The e-GIF performs the same function in e-government as the Road Code does on
the highways. Driving would be excessively costly, inefficient, and ineffective if
road rules had to be agreed each time one vehicle encountered another.
</blockquote>

==== Portuguese law definition ====
The Portuguese Open Standards Law,<ref>{{Cite web |title=Law no. 36/2011, of June 21st |url=https://diariodarepublica.pt/dr/detalhe/lei/36-2011-670285 |access-date=2023-09-21 |website=diariodarepublica.pt}}</ref> adopted in 2011, demands the use of Open Standards, and is applicable to sovereign entities, central public administration services (including decentralized services and public institutes), regional public administration services and the public sector. In it, Open Standards are defined thus:

<blockquote>
a) Its adoption is fruit off an open decision process accessible to all interested parties;

b) The specifications document must have been freely published, allowing its copy, distribution and use without restrictions;

c) The specifications document cannot cover undocumented actions of processes;

d) The applicable intellectual property rights, including patents, have been made available in a full, irrevocable and irreversible way to the Portuguese State;

e) There are no restrictions to its implementation.
</blockquote>

==== Spanish law definition ====
A law passed by the [[Spanish Parliament]]<ref>{{cite web|url=http://www.boe.es/boe/dias/2007/06/23/pdfs/A27150-27166.pdf|title="Ley 11/2007" of Public Electronic Access of the Citizens to the Public Services, June, 22nd 2007|website=boe.es|access-date=18 March 2018}}</ref> requires that all electronic services provided by the Spanish public administration must be based on open standards. It defines an open standard as royalty-free, according to the following definition (ANEXO Definiciones k):

<blockquote>
An open standard fulfills the following conditions:
* it is public, and its use is available on a free [gratis] basis, or at a cost that does not imply a difficulty for the user.
* its use is not subject to the payment of any intellectual [copyright] or industrial [patents and trademarks] property right.
</blockquote>

==== South African Government definition ====
The [[South African Government]] approved a definition in the "Minimum Interoperability Operating Standards Handbook" (MIOS).<ref>{{cite web|url=http://www.dpsa.gov.za/documents/egov/MIOSVer4_1_2007.pdf|title=Government of South Africa, MIOS Version 4.1 2007|website=dpsa.gov.za|access-date=18 March 2018}}{{Dead link|date=August 2025 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

For the purposes of the MIOS, a standard shall be considered open if it meets all of these criteria. There are standards which we are obliged to adopt for pragmatic reasons which do not necessarily fully conform to being open in all respects. In such cases, where an open standard does not yet exist, the degree of openness will be taken into account when selecting an appropriate standard:

#it should be maintained by a non-commercial organization
#participation in the ongoing development work is based on decision-making processes that are open to all interested parties.
#open access: all may access committee documents, drafts and completed standards free of cost or for a negligible fee.
#It must be possible for everyone to copy, distribute and use the standard free of cost.
#The intellectual rights required to implement the standard (e.g.essential patent claims) are irrevocably available, without any royalties attached.
#There are no reservations regarding reuse of the standard.
#There are multiple implementations of the standard.

====UK government definition====
The [[UK government]]'s definition of open standards applies to software interoperability, data and document formats. The criteria for open standards are published in the "Open Standards Principles" policy paper and are as follows.<ref>Cabinet Office, [https://www.gov.uk/government/publications/open-standards-principles Open standards principles], published 9 April 2013, updated 5 April 2018</ref>
<blockquote>
#Collaboration – the standard is maintained through a collaborative decision-making process that is consensus based and independent of any individual supplier. Involvement in the development and maintenance of the standard is accessible to all interested parties.
#Transparency – the decision-making process is transparent, and a publicly accessible review by subject matter experts is part of the process.
#Due process – the standard is adopted by a specification or standardisation organisation, or a forum or consortium with a feedback and ratification process to ensure quality.
#Fair access – the standard is well documented, publicly available and free to use.
#Mature – completely developed, unless they are in the context of creating innovative solutions.
#Independent of platform, application and vendor – supported by the market with several implementations.
#Rights – rights essential to implementation of the standard, and for interfacing with other implementations which have adopted that same standard, are licensed on a royalty-free basis that is compatible with both open source and proprietary licensed solutions. These rights should be irrevocable unless there is a breach of licence conditions.
</blockquote>

The [[Cabinet Office]] in the UK recommends that [[Departments of the Government of the United Kingdom|government departments]] specify requirements using open standards when undertaking [[procurement]] exercises in order to promote interoperability and re-use, and avoid technological lock-in.<ref>Cabinet Office, [https://webarchive.nationalarchives.gov.uk/ukgwa/20110405235749mp_/http://www.ogc.gov.uk/documents/PPN_3_11_Open_Standards.pdf Procurement Policy Note – Use of Open Standards when specifying ICT requirements.

The decree includes the requirement that the Venezuelan public sector must use free software based on open standards, and includes a definition of open standard:

<blockquote>
Article 2: for the purposes of this Decree, it shall be understood as

k) Open standards: technical specifications, published and controlled by an organization in charge of their development, that have been accepted by the industry, available to everybody for their implementation in free software or other [type of software], promoting competitivity, interoperability and flexibility.

#Availability: Open Standards are available for all to read and implement.
#Maximize End-User Choice: Open Standards create a fair, competitive market for implementations of the standard. They do not lock the customer into a particular vendor or group.
#No Royalty: Open Standards are free for all to ''implement'', with no royalty or fee. ''Certification'' of compliance by the standards organization may involve a fee.
#No Discrimination: Open Standards and the organizations that administer them do not favor one implementor over another for any reason other than the technical standards compliance of a vendor's implementation. Certification organizations must provide a path for low and zero-cost implementations to be validated, but may also provide enhanced certification services.
#Extension or Subset: Implementations of Open Standards may be extended, or offered in subset form. However, certification organizations may decline to certify subset implementations, and may place requirements upon extensions (see ''Predatory Practices'').
#Predatory Practices: Open Standards may employ license terms that protect against subversion of the standard by ''[[Embrace, extend and extinguish|embrace-and-extend]]'' tactics. The licenses attached to the standard may require the publication of reference information for extensions, and a license for all others to create, distribute, and sell software that is compatible with the extensions. An Open Standard may not otherwise prohibit extensions.

Bruce Perens goes on to explain further the points in the standard in practice. With regard to availability, he states that "any software project should be able to afford a copy without undue hardship. The cost should not far exceed the cost of a college textbook".<ref name=parens/>

==== Microsoft's definition ====
{{see also|Microsoft Open Specification Promise}}
Vijay Kapoor, national technology officer, [[Microsoft]], defines what open standards are as follows:<ref>{{cite web|url=http://www.efytimes.com/efytimes/fcreative.asp?edid=27036|title=OOXML: To Be, or Not To Be<!-- Bot generated title -->|website=efytimes.com|access-date=18 March 2018}}</ref>

<blockquote>
Let's look at what an open standard means: 'open' refers to it being royalty-free, while 'standard' means a technology approved by formalized committees that are open to participation by all interested parties and operate on a consensus basis. An open standard is publicly available, and developed, approved and maintained via a collaborative and consensus driven process.
</blockquote>

Overall, Microsoft's relationship to open standards was, at best, mixed. While Microsoft participated in the most significant standard-setting organizations that establish open standards, it was often seen as oppositional to their adoption.<ref name="CassonRyan2006">{{Citation |ssrn=1656616 |author1=Casson, Tony |author2=Ryan, Patrick S. |contribution=Open Standards, Open Source Adoption in the public sector, and their relationship to Microsoft's market dominance |date=May 1, 2006 |title=Standards edge: unifier or divider? |editor=Sherrie Bolin |page=87 |publisher=Sheridan Books }}</ref>

=== By non-profit organizations ===
==== Open Source Initiative's definition ====
The [[Open Source Initiative]] defines the requirements and criteria for open standards as follows:<ref>{{cite web|url=http://opensource.org/osr|title=Open Standards Requirement for Software – Open Source Initiative|website=opensource.org|date=24 July 2006 |access-date=18 March 2018}}</ref>

The Requirement

An "open standard" must not prohibit conforming implementations in open source software.

The Criteria

To comply with the Open Standards Requirement, an "open standard" must satisfy the following criteria. If an "open standard" does not meet these criteria, it will be discriminating against open source developers.

# No Intentional Secrets: The standard MUST NOT withhold any detail necessary for interoperable implementation. As flaws are inevitable, the standard MUST define a process for fixing flaws identified during implementation and interoperability testing and to incorporate said changes into a revised version or superseding version of the standard to be released under terms that do not violate the OSR.
# Availability: The standard MUST be freely and publicly available (e.g., from a stable web site) under royalty-free terms at reasonable and non-discriminatory cost.
# Patents: All patents essential to implementation of the standard MUST:
#* be licensed under royalty-free terms for unrestricted use, or
#* be covered by a promise of non-assertion when practiced by open source software
# No Agreements: There MUST NOT be any requirement for execution of a license agreement, NDA, grant, click-through, or any other form of paperwork to deploy conforming implementations of the standard.
# No OSR-Incompatible Dependencies: Implementation of the standard MUST NOT require any other technology that fails to meet the criteria of this Requirement.

==== World Wide Web Consortium's definition ====
As a provider of Web technology [[Information and Communications Technology|ICT]] Standards, notably [[XML]], [[http]], [[HTML]], [[CSS]] and [[WAI]], the [[World Wide Web Consortium]] (W3C) follows a process that promotes the development of quality standards.<ref>[http://www.w3.org/2005/09/dd-osd.html Definition of Open Standards] World Wide Web Consortium</ref>

Looking at the result, the spec alone, up for adoption, is not enough. The participative/inclusive process leading to a particular design, and the supporting resources available with it should be accounted when we talk about Open Standards:

<blockquote>
*transparency (due process is public, and all technical discussions, meeting minutes, are archived and referencable in decision making)
*relevance (new standardization is started upon due analysis of the market needs, including requirements phase, e.g. accessibility, multi-linguism)
*openness (anybody can participate, and everybody does: industry, individual, public, government bodies, academia, on a worldwide scale)
*impartiality and consensus (guaranteed fairness by the process and the neutral hosting of the W3C organization, with equal weight for each participant)
*availability (free access to the standard text, both during development, at final stage, and for translations, and assurance that core Web and Internet technologies can be implemented Royalty-Free)
*maintenance (ongoing process for testing, errata, revision, permanent access, validation, etc.)
</blockquote>

In August 2012, the W3C combined with the IETF and IEEE to launch OpenStand <ref name="OpenStand"/> and to publish The Modern Paradigm for Standards. This captures "the effective and efficient standardization processes that have made the Internet and Web the premiere platforms for innovation and borderless commerce".

==== Digital Standards Organization definition ====

The [[Digital Standards Organization]] (DIGISTAN) states that "an open standard must be aimed at creating unrestricted competition between vendors and unrestricted choice for users."<ref name="Defining Open Standard">{{Cite web |url=http://www.digistan.org/text:rationale |title=Defining "Open Standard" |access-date=2008-06-03 |archive-url=https://web.archive.org/web/20160420091338/http://www.digistan.org/text:rationale |archive-date=2016-04-20 |url-status=dead }}</ref> Its brief definition of "open standard" (or "free and open standard") is "a published specification that is immune to vendor capture at all stages in its life-cycle". Its more complete definition follows:

<blockquote>
* "The standard is adopted and will be maintained by a not-for-profit organization, and its ongoing development occurs on the basis of an open decision-making procedure available to all interested parties.
* The standard has been published and the standard specification document is available freely. It must be permissible to all to copy, distribute, and use it freely.
* The patents possibly present on (parts of) the standard are made irrevocably available on a royalty-free basis.
* There are no constraints on the re-use of the standard.

A key defining property is that an open standard is immune to vendor capture at all stages in its life-cycle. Immunity from vendor capture makes it possible to improve upon, trust, and extend an open standard over time."<ref>{{Cite web |url=http://www.digistan.org/open-standard:definition |title=What is an Open Standard? |access-date=2008-06-03 |archive-url=https://web.archive.org/web/20100805073355/http://www.digistan.org/open-standard:definition |archive-date=2010-08-05 |url-status=dead }}</ref>
</blockquote>

This definition is based on the EU's EIF v1 definition of "open standard", but with changes to address what it terms as "vendor capture". They believe that "Many groups and individuals have provided definitions for 'open standard' that reflect their economic interests in the standards process. We see that the fundamental conflict is between vendors who seek to capture markets and raise costs, and the market at large, which seeks freedom and lower costs... Vendors work hard to turn open standards into franchise standards. They work to change the statutory language so they can cloak franchise standards in the sheep's clothing of 'open standard'. A robust definition of "free and open standard" must thus take into account the direct economic conflict between vendors and the market at large."<ref name="Defining Open Standard"/>

==== Free Software Foundation Europe's definition ====
The [[Free Software Foundation Europe]] (FSFE) uses a definition which is based on the [[European Interoperability Framework]] v.1, and was extended after consultation with industry and community stakeholders.<ref>https://fsfe.org/freesoftware/standards/def.en.html [https://web.archive.org/web/20090710000959/http://fsfe.org/projects/os/def.html old ver]</ref> FSFE's standard has been adopted by groups such as the SELF EU Project, the 2008 Geneva Declaration on Standards and the Future of the Internet, and international [[Document Freedom Day]] teams.

According to this definition an Open Standard is a format or protocol that is:

# Subject to full public assessment and use without constraints in a manner equally available to all parties;
# Without any components or extensions that have dependencies on formats or protocols that do not meet the definition of an Open Standard themselves;
# Free from legal or technical clauses that limit its utilisation by any party or in any business model;
# Managed and further developed independently of any single vendor in a process open to the equal participation of competitors and third parties;
# Available in multiple complete implementations by competing vendors, or as a complete implementation equally available to all parties.

==== FFII's definition ====
The [[Foundation for a Free Information Infrastructure]]'s definition is said{{by whom|date=September 2015}} to coincide with the definition issued in the European Interoperability Framework released in 2004.

<blockquote>
A specification that is public, the standard is inclusive and it has been developed and is maintained in an open standardization process, everybody can implement it without any restriction, neither payment, to license the IPR (granted to everybody for free and without any condition). This is the minimum license terms asked by standardization bodies as W3C. Of course, all the other bodies accept open standards. But specification itself could cost a fair amount of money (i.e. 100–400 Eur per copy as in ISO because copyright and publication of the document itself).<ref>{{Cite web|date=2007-01-18|title=FFII Workgroup on Open Standards – FFII|url=http://action.ffii.org/openstandards|access-date=2021-11-15|archive-url=https://web.archive.org/web/20070118141247/http://action.ffii.org/openstandards|archive-date=2007-01-18}}</ref>

==Patents==
In 2002 and 2003 the controversy about using [[reasonable and non-discriminatory]] (RAND) [[licensing]] for the use of patented technology in [[web standard]]s increased. [[Bruce Perens]], important associations as [[Free Software Foundation|FSF]] or [[Foundation for a Free Information Infrastructure|FFII]] and others have argued that the use of [[patent]]s restricts who can implement a standard to those able or willing to pay for the use of the patented technology. The [[requirement]] to pay some small amount per user, is often an insurmountable problem for free/open source software implementations which can be redistributed by anyone. [[Royalty-free]] (RF) licensing is generally the only possible license for free/open source software implementations. Version 3 of the [[GNU General Public License]] includes a section that enjoins anyone who distributes a program released under the GPL from enforcing patents on subsequent users of the software or derivative works.

One result of this controversy was that many governments (including the Danish, French and Spanish governments singly and the EU collectively) specifically affirmed that "open standards" required royalty-free licenses. Some standards organizations, such as the [[W3C]], modified their processes to essentially only permit royalty-free licensing.

Patents for [[software patent|software, formulas and algorithms]] are currently enforceable in the US but not in the EU. The European Patent Convention expressly prohibits algorithms, business methods and software from being covered by patents.<ref>[http://www.european-patent-office.org/legal/epc/e/ar52.html#A52_2_c European Patent Convention Article 52 paragraph (2)(c)]</ref> The US has only allowed them since 1989 and there has been growing controversy in recent years as to either the benefit or feasibility.

A standards body and its associated processes cannot ''force'' a patent holder to give up its right to charge license fees, especially if the company concerned is not a member of the standards body and unconstrained by any rules that were set during the standards development process. In fact, this element discourages some standards bodies from adopting an "open" approach, fearing that they will lose out if their members are more constrained than non-members. Few bodies will carry out (or require their members to carry out) a full patent search. Ultimately, the only sanctions a standards body can apply on a non-member when patent licensing is demanded is to cancel the standard, try to rework around it, or work to invalidate the patent. Standards bodies such as W3C and OASIS require{{Citation needed|date=June 2008}} that the use of required patents be granted under a royalty-free license as a condition for joining the body or a particular working group, and this is generally considered enforceable.{{Citation needed|date=June 2008}}

Examples of patent claims brought against standards previously thought to be open include [[JPEG#Patent controversy|JPEG]] and the [[Rambus]] case over [[DDR SDRAM]]. The [[H.264/MPEG-4 AVC#Patent licensing|H.264 video codec]] is an example of a standards organization producing a standard that has known, non-royalty-free required patents.

Often the scope of the standard itself determines how likely it is that a firm will be able to use a standard as patent-like protection. Richard Langlois argues that standards with a wide scope may offer a firm some level of protection from competitors but it is likely that [[Schumpeterian]] [[creative destruction]] will ultimately leave the firm open to being "invented around" regardless of the standard a firm may benefit from.<ref name="Langlois, Richard N 1999"/>

The incalculable loss of life and damage to property was exacerbated by the fact that responding agencies and non-governmental groups were unable to share information vital to the rescue effort. Each was using different data and document formats. Relief was slowed, and coordination complicated. [...] |Mosibudi Mangena|Opening address of SATNAC 2005}}

==Legitimacy of standards==
{{POV-section|date=December 2007}}{{Unreferenced-section|date=July 2007}}

'''Legitimate standards''' are, to some critics, only those [[standardization|standard]]s whose documentation can be downloaded free-of-charge, and which can be implemented without [[royalties]] or other restrictions.

[[Request for Comments|Internet Request for Comments]] (RFCs) are an example of such [[open standards]]. However, many standards organisations attempt to support themselves by restricting standard documentation through [[copyright]]s (and selling copies), and restricting implementation through [[patent]]s (and selling licenses). 
While this second approach does solve the issue of how to pay for the time (and sometimes travel for meetings, and in some cases on-location research) of those writing the standards, it can cause significant problems.

Standards which cost money to purchase and/or license cause significant problems for:
* developers of [[free software]] and [[open hardware]];
* electronics hobbyists;
* manufacturers of small-volume products; and 
* those developing new products who [[Startup company|lack sufficient access to capital]].

An engineer may spend more time just trying to figure out what is involved in implementing and licensing such a standard than
it would take to actually implement an open standard. Expensive standards often show evidence of having been [[Design by committee|designed by a committee]]. Sometimes, they appear to have gratuitous deviations from existing practice that appear to serve the
interests of the standards organization in creating protectable [[intellectual property]], rather than the societal interests. When standards documents are not affordable, it can cause trouble for technicians trying to debug systems, as well as intelligent end users trying to evaluate or understand the technology.

Standards committee members sometimes double-dip by selling books or classes on how to implement a standard; the more arbitrary the standard, the more market for these add-on products. Some formal standards are developed by people who are more office politicians than engineers. Sometimes, licensing of standards is also used to [[Digital rights management|circumvent a user's legal rights to fair use copying]] by preventing the development of equipment or software that allows such copying.

Sometimes, standards organizations may involve companies with vested interests that all "contribute" patents (subject to licensing), when freely available [[technology]] would have done better. Some standards organizations appear to collect millions of dollars a year for a single standard, or a small set of closely related standards, yet appear to do very little in terms of active standards development.

There are some alternative ways of funding standards:
* funding by governments (for example, [[NIST]]);
* making money from optional compatibility [[certification mark]] licensing, rather than patent licensing;
* developing standards, and making them open to all to create a market;  
* developing own standards by end-users.
* instituting cost-cutting measures, including using [[teleconference]], rather than expensive travel;
* developing standards by one person, or a few people, and simply offering up for use (such as internet RFCs); where if anyone likes it, they can use it, otherwise, they can come up with a better standard or suggest revisions.

It is worth noting the outcome of the competition between the truly open standards of the [[TCP/IP]] [[protocol stack]] (the basis of the Internet), the designed-by-committee and pay for copies [[OSI model|OSI protocol stack]], and the various vendor [[proprietary]] [[Wide area network|WAN]] standards ([[Decnet]], [[SNA]]). TCP/IP dominates.

Less open standards are more competitive when:
* there are no open alternatives; 
* they get to the market first; 
* extensive marketing is used to prop them up; 
* they have a significant technical advantage.

=== Legitimacy/Openness factors ===
* Is the standard documented?
* Is the standard available for all to use, or is it intended to create a [[monopoly]] or [[vendor lock-in]]?
* Is the documentation available for immediate download, free of charge?
* Can the standard be implemented without payment of [[royalties]], membership, or license fees?
* Does licensing the standard pose other restrictions (such as copy protection enforcement)?
* Is sufficient information available to implement the standard without purchasing official documents?
* Are there any patents interfering with the implementation of the standard?
* Are [[trademark]]s enforced in such a way as to interfere with the use of the standard?
* Does the standard avoid arbitrary deviations from existing standard practice?
* Does the standard use appropriate technology?
* Is the standard supported by multiple companies?
* Are licensing fees stated up front?
* Is uniform licensing available (all companies pay comparable fee per unit)?
* Are licensing fees reasonable for small volumes (1–1000 units)?  Is overhead minimal?
* Are licenses free if the product is free?
* How does the openness of the standard compare to competing standards?
* Is the standard extensible?
* Is the standard locked to a particular platform?

=== Some examples ===
Here are some comparisons between different formats..

* WAN: [[TCP/IP]] is much more open than the [[Open Systems Interconnection|OSI]] protocol suite, DECnet, SNA, etc.
* LAN: TCP/IP is much more open than [[NBF]], the [[NetWare]] protocol stack, etc. 
* Video/Audio: "Ogg [[Vorbis]] Audio" and "Ogg [[Theora]] Video" are much more open than other formats, including those with official standards such as [[MP3]], [[Advanced Audio Coding|AAC]], [[MPEG]]1/2/4, etc. Ogg standards are free. Vorbis is patent-free and Theora's patents are automatically licensed, free of charge. Vorbis also appears to offer better audio quality than MP3 or AAC. For [[streaming audio]], [[Icecast]] and [[Peercast]] are more open than RealPlayer or Windows Media Player. MPEG2 patents reportedly cost $2.50 per device (no minimums or annual fees), but there are additional royalties for streaming services, media, etc.
* Instant Messaging:  [[Jabber]] is much more open than [[AIM]], [[ICQ]], [[MSN]], [[Yahoo Messenger]], etc. However, companies such as [[AOL]] have tried to sabotage Jabber by blocking the gateways between Jabber and AIM/ICQ.
* Office Applications: [[OpenDocument]] and [[Office Open XML]] files are much more open than the old [[Microsoft Office]] binary file formats which are proprietary Microsoft controlled formats that are freely available and free to implement. 
* Flash memory: [[Multi Media Card|MMC]] is more open than [[Secure Digital Card]] (though the two are largely interchangeable, if used carefully. SD-card is more open than [[xD-Picture Card]] or [[Sony Memory Stick]]. [[CompactFlash]], based closely on [[Advanced Technology Attachment|ATA]], is more open than SD-card.
* [[USB]] appears to be more open than [[FireWire]]. USB standards can be downloaded for free, and there do not appear to be any licensing fees if one does not use the USB-certified logos.  FireWire ports are covered by dozens of patents; these patents can be licensed for $0.25 per device with no minimum or annual fees.

=== Examples outside of computer technology ===
* One of the earliest and most successful examples of an independent standards organization promoting open standards that could be freely used by hobbyists and commercial manufacturers alike has been the [[National Model Railroad Association]]. Prior to the NMRA's inception, most manufacturers had their own proprietary standards for track, wheels, and so forth, and it was quite rare for commercial models made by different manufacturers to operate well together. In 1935, the hobbyists took charge, forming the NMRA, developing open standards to promote free interchange of models, and making it known that even among non-member hobbyists, compliance with those standards would be worth more to a manufacturer than any intentional incompatibility could possibly be.
