Joseki is a server for publishing RDF models on the Web. Models have URLs can be accessed by queries using HTTP GET. As part of the Jena RDF toolkit, it provides a coarse-grained Web API that is based on extracting a subgraph from the published RDF. The extracted RDF can then be processed locally with the fine-grained API provided by Jena. Joseki is extensible - new query languages and new operations can be added without modifying the core system.
