Two comments here:

 1) It's probably better to add a get_properties() to
    semi_rdf.py that returns a list of all matched
    Could be used for the maintainers check in 
    the validation as well.

 2) I don't think we should entirely skip the validation;
    because people will a) make typos (Say use #binding
    instead of #bindings) b) make up stuff
    like:

    http://api.gnome.org/doap-extensions#music-player

    So, the compromise would be to check that if it starts
    with http://api.gnome.org/doap-extensions it has
    to be one of our real categories.
