I'm pleased to announced the next release of Demokritos.
Demokritos is a Python library and content repository implementing the Atom Syndication Format (RFC4287) and Atom Publishing Protocol (currently a standards track Internet-Draft)
You can download the code at http://jtauber.com/2006/demokritos/demokritos-0.2.0.tgz
At this stage, Demokritos is not really intended for anything other than interoperability testing with Atom clients. However, the library for parsing and generating Atom feeds might be useful standalone.
The original post had 4 comments I'm in the process of migrating over.
