Make a tool for RDF graphs validation

[lecoqlibre]

In every connector I'm writing JSON-LD export tests again and again (and it's boring).

It would be great to have a tool that is written once and can be used with any programming language.

It could read JSON-LD files to validate they comply to the DFC standard. This tool could be used on the command line and it could even be built as a service so we would have a monitoring service that would automatically check everything is OK with a platform and send an email when it's not.

There is a lot about RDF validation in the semantic ecosystem. We should be able to use SHAPEs validation. There may even be existing tool for that yet. The code generator could be able to generate SHAPEs files.
