The Reuse Library Interoperability Group (RIG) [#!Moo92!#]
formed in 1991. Terri
Hobbs has chaired TC2 since its creation in July 1991. TC2 took the task of
developing a general data model to support interoperability between many,
widely divergent libraries. As part of this effort, TC2 first developed a
subset data model for interoperability, the Basic Interoperability Data Model
(BIDM) [#!RIG93a!#] that became a RIG proposed standard. TC2 also completed
the draft of the UDM. The UDM includes the BIDM and expands upon it. In
addition, TC2 has begun compiling a preliminary list of vocabulary terms
for use in some of the UDM (and BIDM) attributes.
