Web services, Microsoft developers, WSF and DFS

Shortly after the Documentum 5.2.5 release, customer interest in web services piqued in conjunction with Documentum’s investment in services via service-based business objects. SBOs, as they’re typically referred to, are supported in the Business Object Framework (BOF), which is the codified customization framework for DFC.

So, in order to preserve customer investment in SBOs, the Web Service Framework (WSF) was first released as part of the 5.3 platform release.

Not every SBO is designed to be projected as a web service, though. So, best practice documentation was published to the developer network, which for the most part just captures common sense. (I used to call these web service SBOs “WSBOs.”)

However, service-orientation at the time of D5.3 development was noticeably different than at the time of D6 development. There needed to be a way to target a broader base of existing service implementations (e.g. POJOs) into the realm of Enterprise Content Services.

Rather than controlling web services by insisting on a DFC/BOF (SBO) investment, it was clear that EMC Documentum needed to participate with broader business systems and processes. So, targeting plain old Java objects became a requirement, while also supporting DFC/BOF-based implementations for existing customers.

Rather than forcing service chains to align on content transfer approach, it was clear that EMC Documentum needed to support content transfer choice, empowering each link (service) in the chain to process content on its terms (e.g. as a file or as a stream).

At the same time, the 6.0 platform release provided additional facilities concerning distributed content. So, any new service-oriented offering from EMC Documentum needed to integrate with these facilities and increase their adoption via ease-of-use (integration).

Documentum Foundation Services (DFS) was first released as part of the 6.0 platform release and was designed to meet these, and several other, objectives.

Which brings us back to the .NET-oriented developer. How does DFS service these individuals?

More on each approach, next…
