Is the New Name for OODB.
The openframe cvs page has details about the CVS repository, and pixie itself is in the conveniently named pixie module.
So to summerize what is working now: you can insert any object, and retrieve any object. Retrieval is sped up significantly when using the PQL mini-language through indexing of the object fields.
I've not yet tackled the non-hash object issue, or indexing of things greater than one level deep, but thats okay, because at the moment PQL won't query them anyway.
If you don't want to use PQL you can still give the 'get' method a coderef or a object id to fetch the objects.
