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
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.

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

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
Future of LOM?

• Name change?
• Keep the definition, expand it even?
• Modularizing LOM?
• eggt. 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?

Remarks on IEEE LTSC Process

• Meetings are open to anyone with a material
  interest
• Participation is welcome, whether or not you join
  the LTSC
• Membership (with voting privileges) is
• Annual
• On an individual basis only (not by organization
  or national body)
• Costs 200 per year for LTSC
• IEEE (or IEEE CS) membership and Standards
  Association Membership required for participation
  in formal balloting (Extra 110 per year)
• Most work done via conference calls
• Times arranged for international participation
  (to the extent possible)
• Face-to-face meetings have enabled for remote
  participation
• Active participation possible without extensive
  travel
• SC36 participants are welcome and encouraged to
  participate in WGs and as LTSC members

19
OTHER STATUS UPDATES

• LTSC pursuing a program with IEEE that will
• allow all LSTC standards to be obtained free of
  charge
• remove obstacles concerning translations,
  profiles and other derived works.
• Status of this no cost standards effort
• Currently in fund-raising phase
• Contact is Brian Taliesin, LTSC treasurer
  (briata_at_microsoft.com)
• Updates will be sent to SC36 through liaison
• LTSC launching new Web site and collaborative
  environment.
• Notification will be sent to SC36 through liaison
• Contact Chad Kainz, LTSC Vice Chair,
