RDF/JS for Data Processing

While working on RDF/JS specifications, I fulfilled two roles.

As the chair, I had the goal that every feasible requirement submitted could be implemented based on what is written in the specification.

Federated queries are affected by some more constraints. The SPARQL Named Query proposal allows the explicit reuse of sub-queries. This blog post will describe the problem in more detail, how the SPARQL Named Query can solve it, and how you can try it already.
