I like it, it’s a nice to-the-point definition of what a form would need. We can take that format as a starting point for form-related software infrastructure that would also include the post-to-Discourse system that will be made by @gdpelican, initially for Natalia’s Biennale usage.
Can you publish it please? Best time is asap 
as it is relevant for @gdpelican as input for his development work.
