Thanks.

I dug a bit further and found https://wiki.blazegraph.com/wiki/index.php/REST_API so I tried text/plain, which produces N-triples.

If you send an Accept header for Turtle, the server returns Turtle:

$ curl -H 'Accept: text/turtle' --data-urlencode query='CONSTRUCT { ?item a http://example.com/Human. } WHERE { ?item wdt:P31 wd:Q5. } LIMIT 10' https://query.wikidata.org/sparql @prefix wd: http://www.wikidata.org/entity/ . # ... wd:Q260 a http://example.com/Human . # ...

Unfortunately, specifying an analogous N-Triples header doesn’t work. I’m not sure why – perhaps BlazeGraph just doesn’t support it directly.

Hi:

How can I control the form of CONSTRUCT results from the wikidata query service?

On the web interface I can get the results in various formats (but not something that can be read into SPARQL, I don't think). Using curl all I get is XML/RDF.

What I really want is n-triples so that I can concatenate several results, but Turtle would be better than RDF/XML.

List,

Within a few hours I got very helpful responses on Stackoverflow. See the link.

Thanks!

List,

Here is a question I posed on Stackoverflow (https://stackoverflow.com/questions/51912599/get-records-for-a-list-of-multi...). Can anyone give me pointers?

...

I am mapping multiple entities (Q entries) in Wikidata for which I need the same record of properties (P entries). For sake of this question, say I have a list of five Wikidata entities (Q1, Q2, Q3, Q4, Q5) for which I want to retrieve the same property records (say, P1, P2, and P3). I know all Q and P in advance.

I understand how to pose a SPARQL query for an individual record (say for Q1), and I also understand how to specify the return of labels using the special SERVICE wikibase:label function for P1, P2, and P3.

First question, is there a way to loop over a list of entities (Q1 to Q5) with a given SPARQL query using only SPARQL?

If the answer is No, does any example Python or pseudocode exist for issuing single SPARQL queries looping over a list of external identifiers (Q1 to Q5), say provided as an external text or CSV file?

If there is a simple way to approach this, I'd love to hear.

Thanks!

Best, Mike
