Ecore ODA Driver


The Ecore ODA Driver was created to allow an EMF ECore model to serve as an ODA data source. This makes it simple for BIRT reports to draw data from Ecore models.

This component has been proposed to the new DTP Incubator. It is hoped (perhaps optimistically) that it can join in the Ganymede release in June of 2008.


Tim has written a tutorial for the Ecore ODA Driver at Overcoming Fear.

Below you'll find some of the same information but without the detail or pretty pictures.


The Ecore ODA Driver is currently only available from CVS. After obtaining the code, you may notice the driver has a number of dependencies that are un-met in your workspace:

Using the Driver

Those less familiar with EMF or without a handy EMF model should install the EMF Examples from http://www.eclipse.org/modeling/emf/updates and create an instance of an .extlibrary file with some data. It's outside the scope of this document to describe this process, but typical readers will already have familiarity with EMF editors.

Of course, any serialized EMF model will do, as long as the package has been registered so that the Java classes representing the model are available at runtime.

Create a Report

The primary consumer of ODA data sources is BIRT. Typically, creating a BIRT report is the first step to using the Ecore ODA Driver.

Create an Ecore ODA Data Source

Any ODA drivers registered with the platform show up within BIRT as data source types, each with a wizard to allow for the entry of connection information. In the case of the Ecore ODA Driver, the only information required by the connection is the path to a serialized Ecore model of a registered model type. (If you aren't familiar with registering EMF models, see this question in the EMF-FAQ.) Attempting to load a serialized model for an unregistered package will result in an error.

Create an Ecore ODA Data Set

Once a data source has been created for your Ecore model, use the New Data Set wizard to launch the Ecore ODA Data Set Wizard.
