Re: Use Case: BetaNYC 3/5

Hi Christophe,

Thank you for your answer.

You are right and I think that's the Steve's proposal to get DBpedia to use
the vocabs and build a use case on that. For example, one discussion in
this way is happening in the Public GLD is in this way [1].

Well, perhaps it is still early, but one point for suggesting about the use
of the vocabs is because we are going to propose an extension of DCAT [2]
(according to the charter [3]) to Quality and Granularity Description
Vocabulary. Maybe this is not the best way, but I believe we need to deeply
understand such vocabs.

All the Best,
Ig
