Re: [Wikidata] Federated queries between wikidata and e.g. sparql.uniprot.org
Hi! > What do we need to take into account to figure this out? What are the > constraints/concerns/etc? Hmm... Looks like I maybe spoke too soon. While it is not a problem to make *WDQS* accept federated queries, it may be a problem to make federated queries actually *work*, because production machines do not seem to have direct access to the internet. Which means if we want to make it work, we'd need to ask ops for one-off exceptions to firewall policies, which are usually frowned upon - they are hard to maintain and in general require extra effort and aren't really best practice. Maybe some of the use cases might be better served by TPF server (https://github.com/blazegraph/BlazegraphBasedTPFServer) - this does not enable federated queries per se but enables to produce content that can be queried externally more easily. -- Stas Malyshev smalys...@wikimedia.org ___ Wikidata mailing list Wikidata@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata

Technically, it is possible and shouldn't be very hard to do. We need to figure out which endpoints we want to allow. -- Stas Malyshev smalys...@wikimedia.org ___ Wikidata mailing list Wikidata@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata
[Wikidata] Federated queries between wikidata and e.g. sparql.uniprot.org
Dear Wikidata developers and contributors, I see that it is currently not possible to run federated queries from wikidata to other sparql endpoints. I understand why you are not allowing this in the general case. However, it would be nice to allow this in the special case. Would a patch allowing limited known remote sparql endpoints to org.wikidata.query.rdf.blazegraph.WikibaseContextListener be possible?
