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.

10
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.

Metadata Interoperability CORES

• Met, 18 November 2002, Brussels
• several Standards-Developing Organizations
• CORES is an fifteen-month Accompanying Measure
  under the European Commission's IST Programme in
  the area of metadata interoperability
  http//www.cores-eu.net/
• The meeting achieved consensus on a resolution to
  assign unique identifiers to metadata elements as
  a useful first step towards the development of
  mapping infrastructures and interoperability
  services.
• The participants agreed to promote the
  implementation of this consensus in their
  standards communities and beyond.

12
Resolution

• Whereas
• our metadata standards have "elements" units of
  meaning comparable and map able to elements of
  other standards,
• We agree
• to assign Uniform Resource Identifiers to our
  elements
• to articulate and publish specific policies
  regarding the stability, persistence, and
  maintenance of the URIs assigned to the elements.

Signatories

• EDItEUR, for ONIX
• Library of Congress, for MARC21
• IEEE P1484, for IEEE/LOM
• EuroCRIS, for CERIF
• International DOI Foundation, for the Digital

15
CORES Action Plan

• 1) Finalise and approve the consensus statement
  by e-mail
• before end 2002, involving participants who
  could not
• attend.
• 2) Publicise the consensus statement to a wider
  audience of
• metadata standards initiatives.
• 3) Define and publish URI assignment mechanisms
  in the next
• half year (i.e., by mid-May 2003).
• 4) Assign URIs to elements in the next half year.
• 5) Define and publish URI persistence policies in
  next
• half year.

16
CORES

• IEEE LOM agreed to be CORES signatory
• Approved at LTSC SEC meeting, Dec. 2002
• CORES notified Dec. 2002
• XML binding group working on URI implementation
  plan

17
LOM .2 ISO 11404

• Lead Frank Farance
• Draft document available on LOM site
• Being updated to LOM v1.0
• Lack of participation in the WG is preventing
  forward progress
• Call for volunteers (4 min) by June 27th and
  disband WG if not received.

18
P1484.12.3 XML binding

• PAR approved 2000-12-07
• ARIADNE  IMS created first version of an XML
  DTD. 
• This and some explanatory documentation is now
  posted at http//www.cs.kuleuven.ac.be/erikd/LOM
  /DTDv1/LOMv1.0DTD.html
• Working Group formed May, 2002 discussions and
  activity now underway
• Balloting process began Feb.2003

19
LOM .4 RDF Binding

• Lead Jon Mason
• Extensive work by Mikael Nilsson
• Development proceeding well
• Integration with Dublin Core
• Existing Implementations
• Preparing for first balloting in 2003?

20
LOM Data Model v2.x Next Steps?

• Next LOM data model work
• Do we intend to create point releases? 1.x
• Do we intend to create a v2.0?
• Process to do so??
• Requirements gathering
• LOM 2 or some completely new (larger) Metadata
  activity?
• Role of LTSC LOM?
• Involvement with other groups?
• Community representation?
• Extending the involvement and coverage
• HR, Content Management, Digital Assets,
• Scope of Metadata?
• Learning Objects any content?
• Any and all content, resources, assets
• Any noun (person/place/thing)
• Modularizing LOM?
• eggt. Each category becomes a part of the
  standard

21
Future of LOM?

• Collaboration with SC36?
• Joint working group?
• scope of LOM
• Currently aimed at objects
• Needing to be at relationships between objects,
  levels of granularity, classes of objects,
  dynamic objects, etc.

22
Future of LOM?

• Name change?
• Keep the definition, expand it event?
• 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?
• Addressing Subjective metadata?
• Recommendations from the LOM WG?

23
Next Steps re Future of LOM

• Prioritized list of areas to address
• Straw poll of directions to go
• 1.x vs 2.0 vs do-over
• LOs vs content vs nouns
• Role of LOM (IEEE/LTSC) relative to other groups?
• Accrediting prior work (specs)
• Developing specs?
• Overarching vision, coordination, etc
• SC36 WG4 LRM
• Metadata for Static vs Dynamic objects
• Dynamic vs Static metadata
• Is metadata the solution to the purpose we seek?
• Need to protect existing implementations

24

• Do we pursue and improve metadata or pursue our
  purpose?
• Chasing chaffing points to improve LOM
• Eg flattening the LOM structure?
• Better documentation

25
Priorities

• Requirements gathering
• As other organizations and IEEE work with LOM
  expend resources to 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
