Hello All,
I have uploaded a new version of the proposal. This version contains an example of how SDO containment metadata can be derived from JPA entities.

-- Mr. Blaise Doughan
The document revision named Proposal - Containment and Enterprise Data Models (SDO-EnterpriseDataModel.doc) has been submitted by Mr. Blaise Doughan to the OASIS Service Data Objects (SDO) TC document repository. This document is revision #1 of SDO-EnterpriseDataModel.doc.
Document Description: The SDO spec to date has primarily concerned itself with deriving SDO metadata from XML schema. As such containment has come to represent the concept of nesting as it relates to XML elements. We prefer to think of containment as it relates to data sharing between types.
For the association "residence" between types "Employee" and "Address" if instances of "Employee" may not share references to instances of "Address" then it is a containment relationship:
Containment: employeeDO1.get("residence") == employeeDO2.get("residence"); // This can never be true Non-Containment: employeeDO1.get("residence") == employeeDO2.get("residence"); // This can be true
Using the above interpretation of containment it becomes easy to derive SDO metadata from other sources, such as JPA entities, JAXB objects, relational databases, etc. (the doc provides examples of deriving SDO metadata from a relational database & JPA entities). These sources may not have a concept of nesting, but they are aware of data sharing rules. Of course DataObjects require an XML representation, and containment has been an important part of that. The attached proposal contains an algorithm that makes use of containment properties when they are present and handles things when they are not.
