Anyone know of a Language Server & Client for ShEx in Javascript ?  It would be great to have one so all IDE's can take advantage of it.

I've opened an issue on github:shexSpec/shex.js to inquire as well...  https://github.com/shexSpec/shex.js/issues/58

The schemas can strike a practical balance between capturing current practice and describing a todo list of things to fix on current practice. It's possible we will want to separate those roles. In the meantime, can you survey existing instances and propose a shape which is not too far from the deployed instances?

I sure hope that E10 is *not* the shape for human.  It certainly isn't a
correct shape for humans that belong to subclasses of human (such as  Old
Croghan Man (Q166790) or Delina Filkins (Q1408186)).  E10 is also currently
silent on what information should be present for humans, which I take it to be
the point of having ShEx in Wikidata.

It is also unclear what is means to be the shape for human.  The shape E10-
does not have any information on which items are to be considered against the
shape.  Are all items in Wikidata to be considered (as in the definition of
ShEx)?  That doesn't seem right.  Are all direct instances of human?  That
seems to limiting.  Are all indirect instances of human?  This seems the most
natural, but where is this behaviour given?
