BaseTen is an open source Cocoa database framework for working with PostgreSQL databases, designed with familiar, Core Data -like semantics and APIs.

The BaseTen feature highlights include:

  • BaseTen Assistant imports Core Data / Xcode data models
  • Discovers the database schema automatically at runtime, including 1-1, 1-many and many-many relationships
  • Database changes are propagated to clients automatically, without polling
  • In-memory database objects are uniqued, and objects fetched via relationships are faults by default
  • Support for RDBMS features like database-driven data more...

Note that the developer is purposely misinterpreting the GPL. If you use this for internal use only you have no obligation to distribute the code. I emailed the developer a while ago with this, and their reaction was that they decided to interpret it otherwise for financial reasons.

This FAQ from GNU (the writers of the GPL) makes this clear:

I have modified the licensing information on the BaseTen web site to more closely reflect our view on this issue.

As authors of the GPL, the Free Software Foundation's opinion on this issue is of course important. But the FAQ you mention is a very general one, and does not address many of the practical concerns in using GPL'ed software inside an organization without making the source available.

Trolltech, a major GPL dual license vendor, has this take on the issue: http://troll.no/developer/knowledgebase/190/
