split data from layout

[egonw]

@ozancinar, @Maddocent, I like to propose we move forward and split the data from the model. Markdown+RDFa has served us well, but now that it is going to be use more, I like to split data from the view, so that we can more easily make changes to the how the terms are shown.

I would implement this in a similar way as the cloud: data in JSON, Groovy script to create other formats: Markdown and OWL.

Are you okay if I more this forward? If so, I implement it. I think it would take me a couple of hours.
