Hi David,

Thanks a lot for your answer.

We can now obtain all required data like this: https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q78&form...

The result contains the labels organised by language tags and geo data (P625) that we need as well. This is great!

I was also able to create a OAUTH 2.0 token (linked to my user).

What did not work, was token refreshing (https://www.wikidata.org/wiki/Wikidata:REST_API/Authentication#Non-owner-onl...).

I tried this:

curl --request POST \

--url https://www.wikidata.org/w/rest.php/w/rest.php/oauth2/access_token \

--header 'Content-Type: application/x-www-form-urlencoded' \

--data grant_type=client_credentials \

--data client_id=abc \

--data client_secret=xyz

I get the following response:

{"messageTranslations":{"en":"The requested relative path (/w/rest.php/oauth2/access_token) did not match any known handler"},"httpCode":404,"httpReason":"Not Found"}

Any idea what I am doing wrong?

Thanks again and kind regards,

Tobias

Hi there,

Hi!

Is there a way to get all labels for a certain language without specifying the label string itself? I tried wildcards but it did not work.

Filtering by language is sadly not possible using the LDF endpoint as it would require a FILTER sparql clause.

Language not appearing in the LDF output is sadly a known limitation [0] of the current implementation.

Also note that SPARQL/LDF is not the only way to extract information out of wikidata, have you considered using the wikidata wbgetentities API [1]?

It can be used to extract labels in a certain language [2]. I suppose also that the upcoming wikidata REST api [3] will cover this use case as well.

David.
