How to represent UNION?

[dgarijo]

I don't see how one can represent Unions in a query. I tried to put it as part of the WHERE clause, but at least in the playground doesn't work

The UNION is indeed not supported in the current version.
Probably it is possible to support it in the $where field (investigating on it).

I tried it in the playground without success. I feel a little like rewriting the SPARQL query in JSON. Why not define a frame and a SPARQL query directly?

[pasqLisena]

It depends on the query :) For more plain queries (like the ones in the examples), we think that a unique file is better. Of course, when queries become complicated, I would recommend to use plain SPARQL queries.

Your suggestion about decoupling frame and query is actually interesting.
I am thinking about if we should give to the user the 2 options:

• separately have frame and query;
• use the syntax we have so far.
