So, we should be able to formally specify the "domain" of identifiers. Perhaps
that could be derived from the type constraints in linked properties, but I
think it would make sense as an explicit property on the identifier.
Some identifiers, e.g., GND, VIAF, require special attention because the

Hi Sebastian,
This is huge! It will cover almost all currently existing German companies.
Many of these will have similar names, so preparing for disambiguation is a

A good way for such an approach would be proposing a property for an external

Hi Osma,
re. adding missing items, I've made good experiences with creating input files
for Quickstatements2 (see
https://github.com/zbw/repec-ras/blob/master/bin/create_missing_wikidata.pl).
I've discussed how to best do this in the Wikidata Project Chat before, and
received valuable advice.

Hi,
does anybody know if SQID can be invoked with an URL, which includes an
external id property and its value - similar to

You are right, the header should be correct. There seems to be a long-lasting

In a federated query on my own (Fuseki) endpoint, which reaches out to the
Wikidata endpoint, with values already bound, it seems that I get for each
bound value an entry in the Fuseki log like this:

Hi Markus,
Great that you checked that out. I can confirm that the simplified query worked
for me, too. It took 15.6s and revealed roughly the same number of results

Thanks for your answer. You asked how long the query runs: 8.21 sec (having

shorter runtime: I routinely use queries of similar comple
