Two weeks where I used computer a lot less, due to pain in wrists and hands. It's still not completely cleared up. I did feel well enough to finally release Cog version 0.3.
Cog is the Checkpointed Object Graph object database, providing semi-transparent persistence for large sets of interrelated Python objects. It handles automatic loading of objects on reference, and saving of modified objects back to disk. Reference counting is used to automatically remove no longer referenced objects from storage, and objects will be automatically be attached to the database if a persistent object references them.
It was originally written by Oliver Jowett, but I am now maintaining it.
