For the record, this is the "game engines written in C/C++/Objective C

Re: [DBpedia-discussion] rest api for dbpedia
Hi Joe,
both linked data and sparql are REST. I guess what you are looking for
is some sort of swagger/json API, which sometimes aren't real REST.
SPARQL is really the way to go, especially, if you already have the URI.
First do:
SELECT distinct ?p count(?p) as?count {
?p ?o
} order by desc (?count)
https://dbpedia.org/snorql/?query=SELECT+distinct+%3Fp+count%28%3Fp%29+as%3Fcount+%7B+%0D%0A%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FSource_%28game_engine%29%3E+%3Fp+%3Fo%0D%0A%7D+order+by+desc+%28%3Fcount%29+
then select the props you need:
SELECT * {
OPTIONAL {
?license . }
OPTIONAL {
?pl . }
}
https://dbpedia.org/snorql/?query=SELECT+*+%7B+%0D%0AOPTIONAL+%7B+%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FSource_%28game_engine%29%3E+%3Chttp%3A%2F%2Fdbpedia.org%2Fontology%2Flicense%3E+%3Flicense+.+%7D%0D%0AOPTIONAL+%7B+%3Chttp%3A%2F%2Fdbpedia.org%2Fresource%2FSource_%28game_engine%29%3E++%3Chttp%3A%2F%2Fdbpedia.org%2Fontology%2FprogrammingLanguage%3E+%3Fpl+.+%7D%0D%0A%7D+
here is a list of all accept headers for SPARQL on dbpedia.org/sparql
text/html
text/x-html+tr
auto
application/vnd.ms-excel
application/sparql-results+xml
application/sparql-results+json
application/javascript
text/turtle
application/rdf+xml
text/plain
text/csv
text/tab-separated-values
you can also query 1000 uris at once, if you rewrite the query a bit or
let chatgpt do it. Not sure how to get the language.

I want to use an rest api (if possible, not spark) to get the language, license

Is there a rest api already rxisting please.?

Re: [DBpedia-discussion] rest api for dbpedia
DBpedia also supports Linked Data. You can request RDF formats using the resource (not the page) URIs, for example: curl -L -H "Accept: text/turtle" 'http://dbpedia.org/resource/Source_(game_engine)' On Sun, Apr 6, 2025 at 3:07 AM joe Alambert wrote: > > I finally decided to migrate from sparql client. > > Best regards. > > On Sat, Apr 5, 2025 at 9:08 PM joe Alambert wrote: >> >> Hello. >> >> I want to use an rest api (if possible, not spark) to get the language, >> license and programming language of a game engine page found previously with >> the lookup api.
