Manuel Fiorelli Armando stellato Dereferenciation System a method to dereference the identifiers defined by a dataset stable HTTP SPARQL Provider a dataset deployment that supports the SPARQL HTTP Protocol RDF Repository a deployment of a dataset on an RDF store technology stable stable SPARQL Endpoint a data service enabling SPARQL queries over a dataset stable true SPARQL Endpoint Limitation a limitation of some SPARQL endpoint. This class is an extension point for recording and subsequently reacting in an application-specific manner to any perceived limitation of an endpoint. The focus is on limitations that cannot objectively be defined a-priori, as they rather depend on a number of boundary conditions, such as the task, the underlying access technology and even the specific queries run to perform the task. Such limitations can then be defined in application-specific ontologies reusing this vocabulary archaic SPARQL Endpoint Limitation a limitation of some SPARQL endpoint.

Such limitations can then be defined in application-specific ontologies reusing this vocabulary stable dereferenciation system relates a void:Dataset to a resource describing a method to dereference the identifiers defined by that dataset. Currently only two instances: :standardDereferenciation and :noDereferenciation are available, however this will be extended soon to account for versioning and other URI-transformation needs stable lod relates an abstract dcat:Dataset to a concrete one that represents whatever is published as linked data at the dataset namespace stable master relates an abstract dcat:Dataset to a concrete one that plays the role of master for the dataset development stable SPARQL endpoint limitation relates a SPARQL endpoint to a resource describing some limitation of that endpoint stable standard dereferenciation the method to dereference identifiers by means of HTTP resolution stable no dereferenciation missing support for any dereferenciation method stable
