BDC Metadata Generator

If you're wondering where to start in learning to create BDC( Business Data Catalog) connectors to back-end relational data sources, here's a tool that can save you time: Jonah Burke's Database Metadata Generator. It's a Codeplex project, so anyone can download it and use it, or download the source code to see how it works.

The generated metadata is pretty simple for now and doesn't support all of the options that the BDC provides for, but it's a great learning tool and its capabilities will likely grow as others contribute to this community development project.
