Uses RDF programming libraries to persistently stores triples in memory, on disk, or to interact with triple stores. – Linked Data for Professional Education https://ld4pe.dublincore.org Learning resources tagged by competency Thu, 19 Nov 2020 14:45:03 +0000 en-US hourly 1 https://wordpress.org/?v=4.9.16 JRDF: An RDF Library in Java https://ld4pe.dublincore.org/learning_resource/jrdf-an-rdf-library-in-java/ Tue, 17 Jan 2017 06:46:13 +0000 https://ld4pe.dublincore.org/learning_resource/jrdf-an-rdf-library-in-java/ JRDF is an attempt to create a standard set of APIs and base implementations to RDF using the latest version of the Java language. A key aspect will be to ensure a high degree of modularity and to follow standard Java conventions. It will be similar to other standard Java APIs such as JDBC, XML, Collections, etc. This project is based on the existing RDF libraries and is designed to include the best features from all available sources, such as: Jena, Sesame, Aquamarine, and Sergey Melnik's RDF API.

]]> Using RDFAlchemy Together With RDFLib’s SPARQLStore to Query DBPedia and Process Resources in an Object-Oriented Way https://ld4pe.dublincore.org/learning_resource/using-rdfalchemy-together-with-rdflibs-sparqlstore-to-query-dbpedia-and-process-resources-in-an-object-oriented-way/ Wed, 11 Jan 2017 06:45:38 +0000 https://ld4pe.dublincore.org/learning_resource/using-rdfalchemy-together-with-rdflibs-sparqlstore-to-query-dbpedia-and-process-resources-in-an-object-oriented-way/ The author of this blog posts shares his work towards manipulating RDF graphs with Python to create an application that can handle Linked Datar esources in an Object-Oriented way, (i.e. using Python classes rather than tables, sets, or lists of triples). The author's solution ties together RDFLib’s SPARQLStore plugin and RDFAlchemy.

]]> Implementing Graph Transformation Languages using RDF Storage and SPARQL Queries https://ld4pe.dublincore.org/learning_resource/implementing-graph-transformation-languages-using-rdf-storage-and-sparql-queries-2/ Thu, 24 Nov 2016 05:51:18 +0000 https://ld4pe.dublincore.org/learning_resource/implementing-graph-transformation-languages-using-rdf-storage-and-sparql-queries-2/ RDF has so far not been widely used in the context of graph rewriting tools. In this paper, the authors take AToMPM, a research-oriented meta-modelling and graph rewriting tool and extend it by adding RDF-based graph transformation functionality. Addressed is the graph matching problem, generating custom SPARQL queries for each rule pattern, and using them to efficiently perform matches on a source RDF graph.
