Thinking about it, you could do multiple formats, one that's super easy, and gets turned into a profile document and added to the index file on build, or it could use the document directly and modify on the fly.

I'm thinking this because then the users site could be references as a static resource within an rdf graph, rather than just being human readable content.

Foaf profile sounds interesting, we can add support for foaf format. I will read more about foaf and get back to you soon.

I am not sure how this will be of great advantage unless it is integrated into a third party apps(like some other app can send foaf details to stringify.me and create a profile). Pls let me know if you see any specific usecase for this.

Thank you
