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.

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 Data Model Priorities:



Requirements gathering
protect existing implementations
Point release for “chaffing points”


2.0 release to reconsider what is meant by LO and/or
metadata

