I’ve just posted an updated version of ccLicense.py, which I’ve dubbed 0.2. You can find it here . Changes are largely related to the way it extracts work and agent information from the license RDF. The interfaces have been more generalized to accomodate nested RDF structures. However, 0.2 is a step back in terms of license creation; generalizing the extraction interfaces means the interfaces for creation need to be reworked as well. Since the improvments were driven by ccValidator , the creation stuff was left behind. I hope to have a more complete version ready in the near future. As always, comments and feedback are welcome.
