I think it's hard to box submissions into a specific set of categorizations, simply because people use different language and have different mental models.  For this kind of open dialogue, I prefer having the community itself contribute its tags as NAPA has done.  Perhaps it might be valuable to pre-seed the tags with a set of common categories.  Also, a semantic element that can bridge the tags would be helpful for finding related submissions.

I concur with the need to standardaize terminanology and conceptual elements as moving forward.  It matters not what type of analogy one wants to make, whether the Tower of Babel to the term "football", it behooves us to define specific terms of art and technical matter so that we can move forward more readily and not c onstantly be re-orienting ourselves.  Additionally as infered, there is a need to ensure that there is concensus on terms and understanding from a contractual and legal perspective.
