Hi Peter, iirc Openlink has some usage rules to ensure fair usage. if you need only labels you can download only the label* datasets from the download page and add them in your database http://downloads.dbpedia.org/2015-10/core/
or use our newly introduced dockerized DBpedia https://github.com/dbpedia/Dockerized-DBpedia to host a complete local 2015-10 version Cheers, Dimitris On Tue, Apr 5, 2016 at 1:30 AM, Peter Neuroth <[email protected]> wrote: > Hello, > > we are currently working on a tool that uses dbpedia to gather the > rdfs:label(s) behind certain urls. > We use nodejs to query at http://dbpedia.org/sparql.
