RDF/Jena: a simple extension for XSLT/XALAN. Testing with NCBI-Gene
In a previous post, I've shown that the XALAN XSLT engine can be extended with custom function returning a DOM Document that will be used by the xslt-stylesheet. Here, I'll create an extension for XALAN getting some RDF statements from a Jena/RDF model. The RDF model will be loaded in memory but one can imagine to use a persistent model ( TDB or SDB). I'll download a record from NCBI-gene, transfo
On Directly Mapping Relational Databases to RDF and OWL (Extended Version)
Mapping relational databases to RDF is a fundamental problem for the development of the Semantic Web. We present a solution, inspired by draft methods defined by the W3C where relational databases are directly mapped to RDF and OWL. Given a relational database schema and its integrity constraints, this direct mapping produces an OWL ontology, which, provides the basis for generating RDF instances.
WebPIE
WebPIE (Web-scale Parallel Inference Engine) is a MapReduce distributed RDFS/OWL inference engine written using the Hadoop framework. This engine applies the RDFS and OWL ter Horst rules and it materializes all the derived statements. WebPIE encodes Semantic Web reasoning as a set of Map and Reduce operations, tapping on the power of the MapReduce programming model for performance, fault-tolerance
Vocabulary Mapping Framework (VMF) project
VMF matrix The VMF matrix is a tool which can be used to automatically compute the "best fit" mappings between terms in controlled vocabularies in difference metadata schemes and messages of interest to the educational, bibliographic and content publishing sectors. The current, "alpha" release of the VMF matrix is available as a single ontology in RDF triples in the TTL format. Two versions are av
