I'm bringing this in a separate thread.

Validation results are very important for the progress of this WG and
should be a standalone deliverable.

Take sparql for instance, it's not only the syntax that makes it useful but
what one expects to get when he executes a query. Having non standardised
sparql responses makes clients break.

In addition, it is the results we want to get that should partially drive
the standard, not the other way around.

In RDFUnit we provide flexible validation execution plans that range from:
Success / fail
Success / fail per constraint
Fails with error counts
Individual resources that fail per constraint
And enriched failed resources with annotations

Of course there can be other type of reports. This WG should try and
identify the most common ones and define a flexible vocabulary that defines
the report type along with the results.

Right now in this charter, what someone expects from a validation execution
is very vague.

Best,
Dimitris
