Michael, First, thanks a lot for the quick reply. I'll try to fix my bug in the get entities by id case and I'll be waiting for the implementation of operations in V4.
PS: The only contribution I can make so far is my project, the generic entity CRUD/Workflow framework I'm trying to build. I use Apache Metamodel for the multiple datasources consumption part, Semantic Web / RDF inference for data integration and Apache Olingo as the front end part. The code is available at: https://code.google.com/p/cognescent/ in 'Sources' into the CBI folder of SVN. It is very inmature, you have to modify Main.java manually to configure the test cases with an xml/rdf datasource or configure a relational datasource (it should use metamodel to enable Olingo show schema and entities of the relational datasource. There is a README to show how to deploy in Tomcat and an issue with the console waiting for prompts until the DataProvider loads. Thanks, please keep me updates. Regards, Sebastian.
