2 2003-18-03 2004-01-27 2 Session Overview: Review of Learning Object Metadata standards Related activities Future directions Discussion, Questions, Suggestions

3 2003-18-03 2004-01-27 3 LOM is a multi-part standard 1484.12.1 Standard for Learning Object Metadata Data Model P1484.12.3 Standard for XML binding for Learning Object Metadata P1484.12.1 data model – Erik Duval P1484.12.4 Standard for RDF binding for Learning Object Metadata P1484.12.1 Data Model – Jon Mason & Mikael Nillson

4 2003-18-03 2004-01-27 4 IEEE 1484.12.1 LOM Data Model 1484.12.1 LOM data model v1.0 now a full IEEE accredited standard June 13, 2002 Bindings of the data model ISO JTC1/SC36 New Work Proposal Widely adopted: ADL SCORM, ARIADNE, ALIC, IMS……… Whats next for the data model??

5 2003-18-03 2004-01-27 5 P1484.12.3 XML binding of LOM Lead = Erik Duval PAR approved 2000-12-07 ARIADNE & IMS created first version of an XML DTD. – This and some explanatory documentation is now posted at: tml Working Group formed May, 2002 First Ballot completed April, 2003 BRC formed and actively meeting Next recirculation ballot expected Feb/March 04

6 2003-18-03 2004-01-27 6 LOM XML WG Update Goal: interoperable LOM instances Mechanism: – XML Schema Definition (.xsd) – Trade-offs in what you can express => set of component xsds that can be put together in different constellations Adds to LOM Data Model – XML data element name ( ) – Vocabulary tokens (atomic)

7 2003-18-03 2004-01-27 7 P1484.12.4 RDF Binding of LOM Lead = Jon Mason PAR approved 2002-03-07 Extensive work by Mikael Nilsson Development proceeding well; Integration with Dublin Core Existing Implementations Deciding on best directions and focus: IEEE Standard or Recommendation? Use of XML?

10 2003-18-03 2004-01-27 10 IEEE 1484.12 LOM Position Statement The IEEE Learning Technology Standards Committee (LTSC) has been providing for the development and maintenance of the Learning Object Metadata (LOM) standard since 1997. This process has been and continues to be an international effort with the active participation on the LOM Working Group by members representing more than 15 countries. Most recently, June 12, 2002, this resulted in the first IEEE accredited standard to be completed by LTSC, the 1484.12.1 LOM data model standard. This is the fist of a multi-part standard for Learning Object Metadata which LTSC LOM is responsible for maintaining, developing and evolving. This responsibility is being fulfilled by current work on bindings of the data model standard and includes developing further versions of the data model standard.

11 2003-18-03 2004-01-27 11 LOM Position Statement (contd) Although the IEEE standard has been well received, recognized and adopted internationally, adoption of the standard is in its early stages. For this reason, the LTSC is interested in avoiding any conditions that create the perception or reality of conflicting or multiple standards being developed for the same purpose. Furthermore, any additional work should take into consideration current implementations to avoid creating unnecessary interoperability issues. Therefore the Learning Object Metadata working group proposes that similar activity concerning the scope and purpose of its efforts continue to be coordinated through the Learning Technology Standards Committee. The IEEE LTSC deeply appreciates the expression of interest in cooperation by all interested parties such as those expressed by ISO/IEC JTC1/SC36 and equally appreciates the excellent technical comments made by SC36 members. The IEEE LTSC therefore invites the participation of members of national bodies represented in SC36 in the maintenance and revision of the LOM standard and is committed to facilitating this.

13 2003-18-03 2004-01-27 13 LOM: Related Activities CORES resolution to assign unique identifiers via URI to metadata elements XML binding group working on URI implementation plan Ottawa Communiqué Abstract model Mappings & Crosswalks FAQ Futures ISO JTC1 SC36 Awaiting response to proposal to do a Joint Committee OCLC/DCMI Joint event 11-14 October 2004, Shanghai Identifiers – CETIS, TSO, ADL, OCLC, etc.

14 2003-18-03 2004-01-27 14 LOM Data Model Priorities: Requirements gathering protect existing implementations Point release for chaffing points From existing practice, from binding implementations, etc. 2.0 release to reconsider what is meant by LO and/or metadata Explore other use cases for metadata Requirement gathering Investigate other types of LOM (metadata) – structural, people, relational Leave LOM v1 alone, facilitate implementations, gather requirements Study groups for large scale future activity

15 2003-18-03 2004-01-27 15 Future of LOM? Name change? Keep the definition, expand it even? Modularizing LOM? eg>. Each category becomes a part of the standard Other forms of or specific types of metadata? Structural, relational, people, etc. Where, when, how to cover relationships between assets Leading to such things as Pattern recognition Ties to sequencing? Metadata for Static vs Dynamic objects Addressing Subjective metadata? Respecting existing implementations Recommendations from CEN/ISSS?
