Background

This service was first created in response to a list of developer challenges published by the Creative Commons and totally revamped during Google Summer of Code 2008. Suggestions and bug reports are always welcome.

Architecture

The validator consists of a Pylons web app called "validator" and a Python support module called "libvalidator." libvalidator handles RDF in many formats; RDF in a comment, RDFa, or inline RDF/XML. HTML is processed by html5lib, and the RDF is passed on to RDFlib. The CC RDF information is accessed via the cc.license Python module that wraps the Creative Commons RDF data.

Source Code

The current implementation is available in git. Setting up the validator requires three modules:

  • cc.license
  • libvalidator
  • validator

(If you are not familiar with our git repository, read our documentation on our source repositories.)

If you don't mind cluttering up your PYTHONPATH, the easiest way to get going to is to clone each of these and run "python setup.py install". After that, read the README in the validator repository; you can easily launch the validator web application, by default listening on localhost port 5000.

Demonstration

The validator can validate both our old RDF-in-a-comment and the recommendation from here on out, RDFa. The validator's front page links to these sample documents.

Additional Resources

Bug reports should be submitted via the CC issue tracker.
