Cellosaurus Dereferencing service

The RDF dereferencing service is the mechanism that, given a URI, returns an RDF description of the resource identified by that URI, enabling clients to retrieve structured, machine-readable data about the resource from the web in different formats.
All the resources defined in the Cellosaurus graph can be dereferenced. It includes the ontology itself, each ontology term, the cell lines, but also the cross-references, the databases and the organizations.

Getting description of RDF entities in different formats

Several formats are supported. The format can be chosen by adding the parameter ?format=<format> or simply by appending the format at the end of the URI, like a file extension.

Resolving RDF entities with a script

The SPARQL protocol (and thus the dereferencing service) 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:
