Background
Early in the struggle for interoperability, a “layered” approach to IT architecture was proposed to promote interoperability, modularization, and reuse – This approach held promise, but did not assure interoperability or
drive common data standards Since the layered architecture model does not specify data
standards, multiple instantiations have developed To manage these data standards, Community of Interests (COIs)
formed to develop common vocabularies– COI process assures a well
defined vocabulary will develop– Now the challenge becomes “how to
optimize data shared across COIs”

In Principle, It Is Simple…But
Too Many Artifacts and Actors, Results in Complex Processes

Tie the Artifacts; Unite the Actors
Metadata Mappings do for data interoperability what Mashup Editors have done for code

Key Thoughts
This strategy that can accommodate multiple data standards– Shows preference for none
Supports process improvement– Process improvements to better streamline a manual
(negotiation intensive) activity that works across COIs Requires only the development of data mappings – That can be supported with automated tools
We suggest that this is a fundamental part of the way forward to manage the data interoperability– Migration from legacy standards,– Unifying the process for generating metadata and code - do for
metadata what mashups is doing for code
