Thanks for your enthusiasm, you can post your questions here.
The project is still young and not funded so I do not have much time to write a comprehensive doc, but I'll do my best.
you actually answered on my question on another reply. I want to make a postgres adapter and use this to retrieve the data, since my current API is written in ruby and it's a bit too slow.
For the funding part! I'd love to help, perhaps a good start would be using it inside some solution :)! Been there done that. Either way kudos.
What do you mean by Api layer for raw data?
