Thu, 24 Nov 2016 05:51:17 +0000

This slide tutorial focuses on using various operators in SPARQL queries. 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.

This page, which contains SPARQL tools, tips, sample queries, is just starting out and the authors hope it can become a resource for useful snippets of information shared among members of the community. There is also a "Tools" page in Sourceforge that lists more substantial contributions and extensions to VIVO. This page also contains an example of a JSON result and a JavaScript example of how to run a SPARQL query and get back JSON.

SPARQL in 11 minutes

Sat, 16 Jan 2016 13:43:29 +0000

This video serves as an introduction to the W3C query language for RDF, SPARQL. Before explaining SPARQL queries themselves, a brief discussion of Linked Data principles (RDF, Triples, HTTP URIs, Ontologies) is given. Sample data and queries used in video are available at http://learningsparql.com/misc/sparqlIn11Minutes.zip .

SPARQL by Example

Abi Evans — Thu, 13 Aug 2015 03:26:17 +0000

This is a very in-depth resource that covers nearly every aspect of SPARQL (both 1.0 and 1.1). Includes example queries (over many datasets), links to endpoints (ARQ, OpenLink's Virtuoso, Redland's Rasqal), and expected results. NOTE: The number of competencies tagged to this resource represent only a small portion its total coverage – it was necessary to omit many of the more commonly tagged competencies to save space.
