Given that [[Metadata (computing)|metadata]] is a set of descriptive, structural and administrative [[data]] about a group of [[computer]] data (for example such as a [[database schema]]), '''Java Metadata Interface''' (or '''JMI''') is a platform-neutral specification that defines the creation, storage, access, lookup and exchange of metadata in the [[Java (programming language)|Java programming language]].<br />
<br />
__TOC__<br />
<br />
== History ==<br />
<br />
The JMI specification was developed under the [[Java Community Process]] and is defined by [[Java Specification Request|JSR]] 40 (a JSR is the formal document that describe proposed specifications and technologies for adding to the [[Java platform]]).<br />
<br />
JMI is based on the [[Meta-Object Facility]] (or MOF) specification from the [[Object Management Group]] (or OMG). The MOF is a [[Metamodeling|metamodel]] (a [[Computer model|model]] of any kind of metadata) used notably to define the [[Unified Modeling Language]] (or UML).<br />
<br />
It supports the exchange of metadata through [[XML Metadata Interchange|XMI]]. XMI is a standard for exchanging metadata information via [[Extensible Markup Language]] (or XML). The MOF/XMI specifications are used for the exchange of UML models.<br />
<br />
== Usage ==<br />
<br />
Essentially, JMI can be used to write tools in Java for manipulating UML models, which can be used in [[Model Driven Architecture]] and/or [[Model-driven engineering|Model Driven Development]]. There are many implementations of JMI, including the Reference Implementation from [[Unisys]], [[SAP NetWeaver]] and [[Sun Microsystems]]'s open-source implementation from the [[NetBeans]] group. JMI is compatible with [[Java SE]] 1.3 and above through:<br />
* Standardized mappings from the MOF modeling constructs to Java;<br />
* Reflective APIs for generic discovery and navigation of metadata models and instances.<br />
