Programatically associates namespaces to prefixes for use in serializing RDF or when parsing SPARQL queries. – 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 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.

]]> Using Ordnance Survey Linked Data: A Python RDFLib Example https://ld4pe.dublincore.org/learning_resource/using-ordnance-survey-linked-data-a-python-rdflib-example/ Thu, 29 Dec 2016 06:44:03 +0000 https://ld4pe.dublincore.org/learning_resource/using-ordnance-survey-linked-data-a-python-rdflib-example/ The author describes how he created a mashup of data.gov.uk and Ordnance Survey Linked Data using just the Python RDFLib library – no triple store is required.

]]> Namespaces and Bindings https://ld4pe.dublincore.org/learning_resource/namespaces-and-bindings/ Sun, 17 Jul 2016 06:32:28 +0000 https://ld4pe.dublincore.org/learning_resource/namespaces-and-bindings/ This documentation discusses the several short-cuts which RDFLib provides for working with many URIs in the same namespace. The namespace module defines many common namespaces such as RDF, RDFS, OWL, FOAF, SKOS. Also discusses using namespaces in SPARQL queries.

]]> An Introduction to RDF and the Jena API https://ld4pe.dublincore.org/learning_resource/an-introduction-to-rdf-and-the-jena-api/ https://ld4pe.dublincore.org/learning_resource/an-introduction-to-rdf-and-the-jena-api/#respond Thu, 13 Aug 2015 03:26:19 +0000 https://ld4pe.dublincore.org/learning_resource/an-introduction-to-rdf-and-the-jena-rdf-api/ This is a tutorial introduction to both W3C's Resource Description Framework (RDF) and Jena, a Java API for RDF. It is written for the programmer who is unfamiliar with RDF and who learns best by prototyping, or, for other reasons, wishes to move quickly to implementation. Some familiarity with both XML and Java is assumed. Explains that RDF data can be represented in XML, but understanding the syntax is secondary to understanding the data model. Also covers methods for querying and manipulating RDF data without using SPARQL.
