WikidataFacts added a comment to T175984: Unable to undo a Wikidata merge.

Rolling back the merge still works, apparently, and afterwards it’s also possible to restore the old version. I used this on Q38906046 (rollback diff), and @MisterSynergy also had success with this on Q34836264 (rollback diff).

WikidataFacts added a comment to T172113: ConcurrentModificationException on non-grouping query with aggregates in SELECT.

Note that this can also occur on grouping queries:

SELECT ?x (COUNT(*) AS ?total) (SUM(?y) AS ?ys) (?ys/?total AS ?ratio) WHERE {
  ?x wdt:P31 wd:Q1.
  BIND(1 AS ?y)
}
GROUP BY ?x

And an alternative workaround is to inline the variables into the SELECT, i. e. (SUM(?y)/COUNT(*) AS ?ratio). The advantage of this is that you can still use ?ratio in a HAVING clause on the grouping query (a FILTER in the outer query is less efficient).

WikidataFacts added a comment to T159723: NotMaterializedException when one branch of UNION binds ?variable and other branch binds ?variableLabel and label service is used.

Here is the real query – the relevant part is: either a statement is a normal statement and has a proper object (?object), in which case I want its label, or it’s a “no value” statement, in which case I want to bind ?objectLabel to "no value"@en. (In the real query, in the end I had to use rdfs:label anyways to make the GROUP_CONCAT in the SELECT clause work.)

WikidataFacts added a comment to T148923: Provide a way to access unencoded page names for sitelinks.

I don’t really like the choice of rdfs:label as predicate. Currently, as far as I’m aware, only items have triples with that predicate, and queries that rely on this assumption might break (and the straightforward fix, ?item a wikibase:Item, isn’t available on WDQS). There’s also the datatype issue that @Esc3300 mentioned, but I don’t think it would be correct to claim that every title on enwiki is in English, either (random examples: Q300 is just some identifier, Sposalizio is Italian, …).

Actually, @yuvipanda suggested to use an IPython.display.IFrame directly instead of an ipywidgets.HTML with an <iframe> inside it, and that works like a charm. I’ve now packaged that into an importable notebook, embedWDQS.ipynb.

The name/title would be a property of the sitelink, not the item. An item can have multiple sitelinks, but each sitelink ought to have exactly one title.

Hrm, perhaps I over-reduced it. In the original query, I of course select ?personLabel in the inner query as well – I only noticed that it wasn’t necessary to get the error message, so I threw it out.

That’s odd, because occasionally curly braces also cause problems, and according to MDN encodeURIComponent always escapes those. I guess that perhaps the browser gets confused when it partially decodes the URL to display it in the location bar…

@Smalyshev: Good to know. So the client would send the cancel request while the query GET request is still pending, and that would then return… 204 No Content? 408 Request Timeout? (I suppose it doesn’t matter – the client knows it canceled the query, it doesn’t need to check the response to detect that.)
