Proposed initial data types are table, hierarchy, and graph. The API will return strings and object references?
Our long term goal is for the query interface to support strongly typed result sets, but the short term is based on tables. We want to implement stats and hierarchy first. The APIs will be provisional (and internal) for now. The new implementations will support coexistance with the existing EMF models.
Joe Toomey pointed out a few observations with EMF: Regardless of its warts, the object oriented EMF data models deliver a lot of value that should not be lost. He is uncomfortable with interfaces that deliver a less valuable sechema based data model because it is easier for a consumer to adopt for example, a Rose model.
The key issue is that we have conflicting goals of functionality versus performance.(Don)
Marius is less clear than Joe that we require a POJO for each part of the schema.
