"Implementation of NIEM 2.0 for the MIOC Federated Query"
A discussion on how the reuse of the LEX\SAR IEPD was implemented to provide
the Michigan Intelligence Operation Center, a standardized view of information
gathered though federated query and response services.  The use case covers
how varying query service data requirements and standards (GJXDM, NCIC, local
APIs, etc.) and response formats and content were captured and normalized to
generate a single business object repository.  The repository provided a
mapping for transforming the variations into a common data model to provide
the end user a single view of the information.
