Everybody seems to be trying that right now! I haven't formally studied computer science nor programming, so it's very hard for me, but I wanted to build a set of tools that would eventually allow for what I call "block-stitching": a UI that mixes the data, its editor (form fields), and its destination template. The idea is to be able to quickly build a web page using nestable components, and being able to export/import the structured data, in as many formats as possible. But since I hardly ever interact with other devs, I might have missed similar projects which are mature enough already? (I just like to build my own crap, it's fun)
