Website should support enhanced categories for documents

Website needs to provide support for three dimensional document categories:

Media type: (Video, Article, Blog)
Source: (Community, Core)
Content type: (Getting started, Tutorials, Advanced)

Currently we only have the ability to show text documents from github. It would be nice to be able to embed and pop up into a modal window for videos (youtube, vimeo, etc), blogs from other sites in a modal iframe, etc.
