We could probably load the rdf we have now into Blazegraph relatively
easily. Updating may be a bit tricky (should we delete historical
items?) but it's possible to figure it out. I'll look into it.

Re: [Wikidata] Do you use the Wikidata entity dump dcatap.rdf?

[Jakob Voß]

Marius Hoch asked last month:

is anyone using the Wikidata entity dump dcatap.rdf at 
https://dumps.wikimedia.org/wikidatawiki/entities/dcatap.rdf?


It is very rarely used and is thus causing us a (probably) undue 
maintenance burden, because of which we plan to remove it.


If anyone is making use of it, please speak up so that we can keep it or 
find a viable alternative.


Well, it is poorly documented maybe this is a reason for its low use? It 
should be mentioned at:


https://www.wikidata.org/wiki/Wikidata:Database_download

I just extended the DCAT-AP item and did some digging into the DCAT-AP 
community: http://www.wikidata.org/entity/Q28600460


DCAT-AP is an application profile (aka "best practice") of the W3C Data 
Catalog Vocabulary, so it's not only to make happy European data catalog 
registries. The main use case is going to be a search across multiple 
open data catalogs (similar to https://datahub.io/ / CKAN but only 
metadata) but by now it seems to be used more to submit data to local 
registries in more than 15 European countries (see this presentation 
from last yeat: https://www.w3.org/2016/11/sdsvoc/brecht).


Anyway, it's a good idea to describe Wikidata dumps in machine readble 
form so why not stick with the current standard?


How about adding the RDF to query.wikidata.org so we can get a current 
list?


PREFIX dcat: 
PREFIX dct: 

SELECT ?url ?date ?size WHERE {
   dcat:dataset ?dump .
  ?dump dcat:distribution [
dct:format "application/json" ;
dcat:downloadURL ?url ;
dcat:issued ?date ;
dcat:byteSize ?bytes
  ] .
}

I created a Phabricator issue for this request:

Cheers,

What's the issue with it? I don't use it but it seems to be part of
standard for dataset descriptions, so I wonder if the issues can be
fixed. I don't know too much about it but from the description is seems
to be very automatable.

If it is used, (although rarely) and you are not sure if it is causing you
any undue burden, why remove a metadata description for linked data
recommended by the EU?
