Scope
IMS Global Learning Consortium

In 1998, IMS and ARIADNE submitted a joint proposal and specification to the IEEE LTSC, which formed the basis of the IEEE LTSC Working Group 12 work on a draft standard for Learning Object Metadata (LOM). The standard developed by this working group is a multi-part standard: part one being a conceptual data schema (which corresponds to the IMS Learning Resource Meta-data Information Model), parts two, three, and four being bindings of this schema in ISO/IEC11404, XML and RDF respectively.
As a result of significant worldwide interest, the IMS Project was incorporated as the IMS Global Learning Consortium (IMS/GLC) in 1999, publicizing the IEEE work through its stakeholder community in the US, UK, Europe, Australia, and Singapore. This evolving stakeholder community has contributed feedback into the ongoing specification development process. In August 1999, IMS/GLC released its Learning Resource Meta-data Specification v1.0 to the public, with minor revisions being released periodically up to v1.2.2 in November 2001. Each of these specification releases was based on updates of the IEEE LOM conceptual data schema with an accompanying XML Binding and Best Practice and Implementation Guide produced by IMS/GLC.
On 12 June 2002, the conceptual data schema of the LOM was approved by the IEEE Standards Association as IEEE 1484.12.1 - 2002 Standard for Learning Object Metadata (IEEE LOM), and the associated XML binding standard was approved as IEEE 1484.12.3 Standard for Extensible Markup Language (XML) Schema Definition Language Binding for LOM in 2005.
With the release of the IEEE 1484.12.1 - 2002, the Information Model of the IMS Meta-data specification has been realigned with the published IEEE standard. The XML Binding of the IMS Meta-data specification has also been realigned with the IEEE 1484.12.3 - 2005 standard. |
Purpose
The IMS Meta-data Specification has been aligned to the IEEE 1484.12.1 and 1484.12.3 standards. IMS/GLC currently publishes general guidance about how an application may use IEEE LOM elements and to assist developers with their meta-data implementations. |

The IMS Learning Resource Metadata specification is composed by three different parts:
- IMS Learning Resource Meta-Data Information Model. It describes the names, definitions, organization, and constraints of the IMS Meta-Data elements. Currently, the IEEE 1484.12.1 - 2002 Standard for Learning Object Metadata is used as the IMS Learning Resource Meta-data Specification.
- IMS Learning Resource Meta-Data XML Binding. It provides a XML representation and XML control files (DTD, XSD) to assist developers with their meta-data implementations. Currenly, the IEEE 1484.12.3 Standard for Extensible Markup Language (XML) Schema Definition Language Binding for Learning Object Metadata is used as the IMS Learning Resource Meta-data XML Binding Specification.
- IMS Learning Resource Meta-Data Best Practice and Implementation Guide. It provides general guidance about how an application may use LOM meta-data elements.
|
None of the IEEE or IMS documents address details of meta-data implementation, such as its architecture, programming language, and data storage approach.

With LOM
- IMS Learning Resource Meta-data is fully based on Learning Object Metadata (LOM) Standard
- IMS member organizations are involved with the IEEE Learning Technology Standards Committee (LTSC) LOM Working Group
|
With DCMI
- The IMS Learning Resources Meta-data Specification incorporates major aspects of the Dublin Core by defining extensions that are appropriate specifically for educational and training materials
- In addition to being an contributing member in IMS, NIST is promoting and evolving the use of IMS Meta-data. A main objective of this coordination is to develop subject taxonomies or content descriptors relevant to specific learning communities
|
With ARIADNE Metadata and the ADL
- ARIADNE and IMS jointly developed a meta-data specification (the IMS Learning Resources Meta-data Specification) for submission to IEEE. Their recommendations have been taking into account in the LOM Standard
- IMS and ARIADNE collaborated to develop a meta-data specification that is being used by the ADL
- The IMS Learning Resources Meta-data Specification incorporates major aspects of the Dublin Core by defining extensions that are appropriate specifically for educational and training materials
|
With the National Institute of Standards and Technology (NIST)
- In addition to being an contributing member in IMS, NIST is promoting and evolving the use of IMS Meta-data. A main objective of this coordination is to develop subject taxonomies or content descriptors relevant to specific learning communities
