Getting description of RDF entities in different formats

Several formats are supported. The format can be chosen by adding the parameter ?format=<format>
where format is one of:

• html (default)
• n3
• ttl
• rdf
• jsonld

Examples

• the ontology in jsonld https://purl.expasy.org/cellosaurus/rdf/ontology/?format=jsonld
• the cello:CancerCellLine class in HTML https://purl.expasy.org/cellosaurus/rdf/ontology/CancerCellLine
• the cello:Xref class in rdf https://purl.expasy.org/cellosaurus/rdf/ontology/Xref?format=rdf
• the cell line CVCL_0030 in ttl https://purl.expasy.org/cellosaurus/rdf/cvcl/CVCL_0030?format=ttl

Resolving RDF entities with a script

The SPARQL protocol is based on the HTTP content negotiation. Instead of using the parameter format as described above,
you can use the 'Accept' header to tell the SPARQL server which mime-type you would like to have in the response.

The following mime-type can be used:

• text/turtle
• application/rdf+xml
• application/n-triples
• application/ld+json
• text/html
