Dipsacus_fullonum added a comment to T255760: Feature request: WDQS WMAPI calls without continuation calls (one call per value of the input variables).

Well, it seems that the requested feature already is here, but is undocumented:

Dipsacus_fullonum added a comment to T196962: Module prefix 'wbeu' is shared between Wikibase\Client\Api\ApiListEntityUsage and Wikibase\Client\Api\ApiPropsEntityUsage.

When I make an API call with action=query and generator=wblistentityusage, like https://en.wikipedia.org/w/api.php?action=query&generator=wblistentityusage&gwbeuentities=Q42 I get an RuntimeException:

Dipsacus_fullonum added a comment to T244341: Stop using blank nodes for encoding SomeValue and OWL constraints in WDQS.

Many queries use the optimizer hint hint:Prior hint:rangeSafe true. when e.g. comparing date or number values with constants in a filter as suggested at https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/query_optimization#Fixed_values_and_ranges. Is there a risc that such queries will fail or give wrong results when somevalue become IRI's, and thus the values will be of different types?

Dipsacus_fullonum added a comment to T244341: Stop using blank nodes for encoding SomeValue and OWL constraints in WDQS.

What we will implement internally for the isSomeValue function won't be doing exactly STRSTARTS( STR(?o), 'http://www.wikidata.org/prop/somevalue/' ) but uses blazegraph vocabulary and inlining facilities, not sure if this answers your question though.

Dipsacus_fullonum added a comment to T244341: Stop using blank nodes for encoding SomeValue and OWL constraints in WDQS.

Yes, isLiteral should still work for properties where the real values are literals. Without knowing the internal workings of Blazegraph I would guess that it is more efficient than STRSTARTS( STR(?o), 'http://www.wikidata.org/prop/somevalue/' ) . Maybe that could be used in some way?

You should be aware that also the functions isIRI or isLiteral (depending on property type) and datatype can be used and probably is used to test if a value is somevalue or a real value.

Dipsacus_fullonum added a comment to T235540: StackOverflowError when SPARQL query uses same variable name before and after aggregation.

Fair enough, but the StackOverflowError seems to be a Blazegraph error, so did anyone report the issue upstream? They have a Jira issue board at https://jira.blazegraph.com/secure/Dashboard.jspa but I don't see anything about this StackOverflowError.

Why don't you close this as invalid and ask people to make correct SPARQL code?

Dipsacus_fullonum added a comment to T244924: wikibase:label autovariables and sparql aggregation function like group_concat don’t work together.

Not a bug. Use of the Label service in automatic mode for unbound variables in "GROUP BY" isn't mentioned as supported in the user manual (https://www.mediawiki.org/wiki/Wikidata_Query_Service/User_Manual#Label_service) so cannot be expected to work.

Things keep changing. At the same page (https://da.wikipedia.org/w/index.php?title=Bruger:Dipsacus_fullonum/sandkasse&oldid=9957579) now the first map, with Wikidata ID's explicit in the JSON code, only show the geoshape for Croatia.

@Aklapper: Now the second map with the SPARQL query is also correct for me. But when the page was created it was only shown as a frame with the legend, but where the map should be, there was only a white empty space.

I found the same problem at huwiki at the page https://hu.wikipedia.org/wiki/Geert_Wilders by looking at the global file usage for
the wrong image at https://commons.wikimedia.org/wiki/File:MarkRutte.jpg. Again when logged in at huwíki I saw the correct image of Geert Wilders. And when I logged off, I saw the image of Mark Rutte in the infobox. Again I fixed it by a null edit of the page.

I found the system for red and blue links: An local, internal link on dawiki is blue if a page with the page name exist on enwiki, and red if no page with the name exist on enwiki. But the links don't link to enwiki.

Dipsacus_fullonum added a comment to T157868: Lua functions do not resolve redirects.

I don't understand why this doesn't have high priority. It makes the functions mw.wikibase.getLabel( id ), mw.wikibase.getDescription( id ), and mw.wikibase.getSitelinkl( id ) unreliable for IDs obtained from a module's arguments or from statement values of type wikibase-entityid in other entities.
