Uses DESCRIBE to extract a single graph containing RDF data about resources. – 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 SPARQL: Using DESCRIBE and CONSTRUCT Tutorial and Quiz https://ld4pe.dublincore.org/learning_resource/sparql-using-describe-and-construct-tutorial-and-quiz/ Thu, 24 Nov 2016 05:51:17 +0000 https://ld4pe.dublincore.org/learning_resource/sparql-using-describe-and-construct-tutorial-and-quiz/ This slide tutorial focuses on using DESCRIBE and CONSTRUCT in SPARQL queries, but also includes other basic operators. Several examples are provided which include the RDF data being queried, the SPARQL query itself, and the result table. This is followed by quiz questions which ask the user to query DBpedia's SPARQL endpoint. The answers to the question (in the form of completed SPARQL queries) are included.

]]> Module 2: Querying Linked Data https://ld4pe.dublincore.org/learning_resource/module-2-querying-linked-data/ Sat, 07 Nov 2015 02:03:58 +0000 https://ld4pe.dublincore.org/learning_resource/module-2-querying-linked-data/ This module looks in detail at SPARQL and introduces approaches for querying and updating semantic data. It covers the SPARQL algebra, the SPARQL protocol, and provides examples for reasoning over Linked Data. The module uses examples from the music domain, which can be directly tried out and ran over the MusicBrainz dataset. This includes gaining some familiarity with the RDFS and OWL languages, which allow developers to formulate generic and conceptual knowledge that can be exploited by automatic reasoning services in order to enhance the power of querying. Note: Will need to also create entries for this modules component parts.
