Re: The 5 stars path

We are in full agreement.

One of my hopes for this WG is that we can indeed lead people to publish 
formats like CSV in the best way (i.e. with good quality metadata) 
without them feeling somehow inferior.

If that leads us to define our own star rating system, I wouldn't mind. 
Something like:

* It's available on the Web in an open format with a declared licence 
(anything less is all but useless).

** As level 1 with good quality discovery metadata (we might refer to 
the DCAT Application profile work as an example).

*** All the above plus structural metadata in the relevant format (e.g. 
CSV+ for CSV, VoID for RDF etc).

This doesn't include quality metrics (which it should), and contact 
details (which it should) - but they might be defined at level 2?

Maybe a start anyway.
