Towards extending and using SPARQL for modular document generation
2008
Proceeding of the eighth ACM symposium on Document engineering - DocEng '08
Preserved Fulltext
RDF is one of the most used languages for resource description and SPARQL has become its standard query language. ...
Nonetheless, SPARQL remains limited to generate automatically documents from RDF repositories, as it can be used to construct only RDF documents. ...
Hence, SPARQL could be used to generate documents. However, the SPARQL CONSTRUCT clause is exclusively limited to use an RDF graph pattern, while one may want to generate XML documents. ...

On Querying Ontologies with Contextual Logic Programming

We describe a system in which Contextual Logic Programming is used as a mediator for knowledge modeled by ontologies. ...
Our system provides the components required to behave as a SPARQL query engine and, as a result of its Logic Programming heritage, it may also recursively interrogate other ontologies or data repositories ...
The implemented SPARQL agent currently does not cover the full specification. Although full SPARQL language support is not the intended objective, we are working towards extending it. ...

SCRY: Extending SPARQL with Custom Data Processing Methods for the Life Sciences

We propose an effective framework for extending SPARQL with custom methods should fulfill four key requirements: generality, reusability, interoperability and scalability. ...
SCRY is a lightweight SPARQL endpoint that interprets parts of basic graph patterns as input for user defined procedures, generating an RDF graph against which the query is resolved on-demand. ...
Another take on extending SPARQL is OGC GeoSPARQL, which "defines a vocabulary for representing geospatial data in RDF, and defines an extension to the SPARQL query language for processing geospatial data ...
