Thanks @preek. I mentioned you guys in [3] above. BTW I'm actually using this parser: https://github.com/orgapp/orgajs for my product (https://braintool.org), so there are other choices. I guess the key thing is a single well defined grammar.
Is GDrive syncing working in Organice these days? I've wanted to demonstrate interop with BrainTool (which syncs to GDrive files) but last I checked there was some bug.
Hence, we are working on building a parser that also acts as a canonical definition here: https://github.com/200ok-ch/org-parser
