Managing an XML Data Model in Your SOA

The Data Administration Newsletter
Gabriel - Managing an XML Data Model in Your SOA

Interesting (to me anyway) article discussing the shifting role of metadata from passive passenger to active driver of Service Oriented Architectures. It’s a little hard to summarize because it’s describing both an architectural approach and the process by which he arrived at this approach. A bit dense, but worth reading if you want to get a sense of the shift in thinking required when designing systems in an SOA context in order to maintain data integrity. This is the author’s summation…

“…For collaborative development on the basis of a fully integrated data model, you need to apply strong version control and be able to treat every object as a true, single-source object. You need a software ‘build’ mechanism around the parts of the integrated data model that are expressed in schemas. You need to shift away from the management of metadata at the schema level. You need a user administration framework with roles, groups, permissions, and security. You need conflict resolution, transaction support, and automated generation of schema releases and associated files from identifiable versions of your integrated data model. You should not need to manage metadata by editing schemas and transformations.”
