The metadata is released under CC0; full texts, transcripts and media files are not part of the dataset and keep their own rights.

The dataset description (VoID and DCAT) lists the vocabularies, the links to other datasets and the current figures:

Resource URIs

Every public item, item set and media has a permanent identifier:

https://data.africamultiple.uni-bayreuth.de/resource/{id}

Opened in a browser, it leads to the record page. Requested by a Linked Data client, it returns RDF in the format asked for.

Example: https://data.africamultiple.uni-bayreuth.de/resource/44460

curl -L -H "Accept: text/turtle" https://data.africamultiple.uni-bayreuth.de/resource/44460

Query with SPARQL

The same graph can be queried directly at a read-only SPARQL endpoint, loaded from the dump:

https://data.africamultiple.uni-bayreuth.de/sparql

Send a query with GET or POST, following the SPARQL 1.1 Protocol. The Accept header chooses JSON, XML, CSV or TSV results. Or write one below, or start from an example, and run it here:
