Add void files which contain alignments

[gatemezing]

Hello @vemonet , great stuff! Here is a small suggestion, that maybe you had already in mind.

Describe the improvement

It would be great to also have alignments between KG using void vocabulary. This could also be by looking up the endpoints for .well-known/void files

Relevant links

• An example of void file at https://270a.info/void.ttl

Corresponding concept

void:Dataset; void:Linkset

Thanks for the suggestion @gatemezing !

That would be an interesting addition, more interesting that the index of DCAT I am currently doing... (why did I chose to index DCAT over VOID datasets?? I have no idea!). I am slowly working on a major update of how the shapes-of-you works, so it might take a bit of time, but I'll add this to the list of things to improve

Getting VOID descriptions and linking them to the SPARQL endpoints they describe would be really cool (in order to try to gather as much info as possible on a SPARQL endpoint, since we already gather queries)

The outstanding question for me is "How can I find those files?"

Currently I search for files in Git repositories that are using keywords related to the semantic web, this would probably work with the example you have given because it is hosted on GitHub (https://github.com/csarven/270a.info), but if you have any suggestion on a good place to find a list of such VOID descriptions I'll be interested

Hello @vemonet.
A pleasure :)
Let me give you some links here:

• https://web.archive.org/web/20210421045302/http://void.rkbexplorer.com/browse/ (archive for rkbexplorer.com )
• https://sparql.uniprot.org/.well-known/void
• https://sparql.rhea-db.org/.well-known/void
• https://beta.sparql.swisslipids.org/.well-known/void

I guess you can go through the sparql endpoints in LOD and see if they have a ./well-known/void. I don't see why the sparqles service (paper here) is not up anymore. But there is a JSON file of SPARQL endpoints at https://github.com/pyvandenbussche/sparqles/blob/master/endpoints.json.
