Hoi,

Sorry for not replying earlier.. I am busy in real life.

It is good to be wrong, particularly about something like this. It is much better to have this engine available to people. What I find relevant is that additional tools are needed to make it shareable. This combined with the learning curve involved, I do not have much time available to me lately, prevent me from exploring it.

I do not really feel the need as WDQ fulfills my needs perfectly. It is because it integrates with the tools that I use.

For me SPARQL may be awesome but as long as it does not integrate with tools and is all over the place, it remains a niche; it is there for some but not others. Once it does integrate and is mostly hidden from view, its power becomes relevant. This has been as true for WDQ; most people use its engine in tools but do not make queries themselves.

Thanks,

GerardM

Hi Gerard. Blazegraph is the name of the open-source SPARQL engine being used to provide the Wikidata SPARQL service.

So Blazegraph *is* available to all of us, at https://query.wikidata.org/ , via both the query editor, and the SPARQL API endpoint.

It's convenient to talk describe some issues with the SPARQL service being "Blazegraph issues", if the issues appear to lie with the query engine.

Other query engines that other people be running might be running might have other specific issues, eg "Virtuoso issues". But it is Blazegraph that the Discovery team and Wikidata have decided to go with.

The beauty of SPARQL is that you can use URLs to show query results (and even query definitions). Ultimately, engine aside, there is massive utility in openly sharing queries and then determining what might the real problem.

Let's use open standards to work in as open a fashion as is possible.
