moiva VS writing

last but not least, Moiva got open-sourced.

I had the same idea. Simple enough, but still. Brackets are simpler to formalize and implement and not harder to explain.

> They also put some thought into designing a query language for their rose-tree-like data model, which might be adaptable to Jevko — though they label only nodes, and Jevko labels both nodes (with suffixes) and arcs (with prefixes).

Yes, that might be interesting to look at, thanks for pointing it out. I have thought about this and came up with some ideas, but haven't decided on anything. I was thinking more along the lines of having the path DSL be simply implemented on top of Jevko, not as a completely separate grammar.

> Maybe that's the subtitle for Jevko? "A minimal Unicode syntax for ordered trees with labeled nodes and labeled arcs." If that's the intended semantics it would be pretty easy to whip up a diagram in Dot to illustrate it.

It's a nice description, but I think a little to detailed and technical to fit into a tagline. Maybe a little explanatory article with the diagram included. Would probably look something like this:

Although I'd gladly see your take on it. ;)
