RE: any standard wys to detect void dataset descriptions?

Same here, four years back, we did similar experiments for
biomedical/healthcare scenarios [1] and results were disappointing.

Hi Axel,

five years ago, we have made a related experiment of trying to find SPARQL
endpoint for a given resource, also via void files [1]. The results were
quite disappointing back then; and it seems like not much has changed in
that respect. Unfortunately, we did not distinguish between (a) finding a
void file and (b) finding a void file pointing to a SPARQL endpoint in our
analysis, but maybe you find it useful anyways.

btw, for DBpedia, it's dbpedia.org/void/Dataset, but that is probably
non-standard. I figured that out by typing "dpbedia void" into Google ;-)

Best,

Heiko

Hi friends, 

 

quick question:

 

Is there any standard way to detect/find void descriptions of datasets
*besides* the one mentioned in https://www.w3.org/TR/void/#discovery
(Section 7)

 

e.g. for dbpedia, neither of the methods from Section 7 seem to be
implemented, or am I mistaken, i.e.

 

1) no void:inDataset links in dbpedia resources e.g. in
http://dbpedia.org/resource/Vienna

 

and 

 

2) none at .well-known/void

 



 

3) nor is there a void.ttl in the root directory
(https://www.w3.org/TR/void/#void-file), i.e. 

 

http://dbpedia.org/void.ttl









... are there any other "common" recipes?









feedback welcome,

Axel
