All Rights Reserved 2 Background n 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 n Since the layered architecture model does not specify data standards, multiple instantiations have developed n 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”

All Rights Reserved 10 Key Thoughts n This strategy that can accommodate multiple data standards –Shows preference for none n Supports process improvement –Process improvements to better streamline a manual (negotiation intensive) activity that works across COIs n Requires only the development of data mappings –That can be supported with automated tools n 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
