Any good 'free' object database on linux

[Kimbro Staken]

It is a database designed to store objects. Now isn't that helpful. :-)

An object database is tightly coupled to an object oriented programming
language and allows you to persist object instances between invocations of a
program. Most implementations are for C++, Java, Smalltalk and recently
Python though never at the same time. They are good for some specialized
applications that are difficult or impossible to map to a relational model
but are not a good general data storage mechanism because of the intimate
coupling with a particular programming language and difficulty in querying.
There is a standard from the ODMG http://www.odmg.org that helps on the
interoperablity front but object database popularity is rapidly declining.
Most object database vendors are now trying to turn their products into XML
databases.
