The new version 5 APIs contain many substantial changes and enhancements of basic structures. When will the corresponding v5 API design guidelines (TMF630) explaining the new features be published?
I have been wondering the same thing. Part 2 (polymorhism) could certainly do with some updates to reflect the new strongly-typed characteristics for v5. Some confirmation on how to deal with dynamic run-time complex characteristics (object/schema references, etc) would be much appreciated too.
