Ecore ODA Driver-Proposal
The Ecore ODA Driver is a proposed component of the DTP Incubator project. It will provide the ability to query Ecore models using OCL by implementing the Open Data Access (ODA) API. The restriction to use OCL (text-based) queries is based on the design of the ODA API. EMF Queries may be supported at runtime in the future.
Initial code has been committed (see CVS, below) but the code is not yet complete. While most of the driver itself is in place the UI requires some finish work.
Contribution tracked at Bugzilla 132958.
It is hoped that a useful release will be complete in time for Ganymede.
The Ecore ODA Driver is only available from CVS. After checking the code out a number of dependencies may be un-met in your workspace such as: Datatools Connectivity, EMF Search, EMF Transaction, and EMF Query. You will also need to install the EMF Model Query OCL Integration feature (or the "Next" button on the New Data Source Wizard for the Ecore ODA Data Source will be disabled) and the Data Tools Platform Enablement for JDBC (or you will see assertion failures in the ConnectionProfileManager for a missing generic db JDBC profile).
Once these dependencies have been met, you can run the BIRT Report Designer (after you have installed BIRT, of course) and create a new report. You might want to use the sample library.ecore and elements.ecore to get started. When adding a Data Source, a new type will display Ecore ODA Data Source and the wizard will allow you to choose an ecore file. Selecting and naming this Data Source and giving the name of an ecore file will allow you to enter a new Data Set. This is, however, pretty much the end of the line. As explained in Status, above, the code is not yet complete. Column selection has not been implemented and the code currently in CVS does not correctly persist preferences.
The Ecore ODA Driver and UI can be checked out of CVS from the Datatools_Project Repository of dev.eclipse.org with a path of org.eclipse.datatools.incubator/plugins.
