SPARQL FAQs

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

This set of FAQs was written before SPARQL 1.1, making it obsolete for practical purposes. However, its treatment of topics such as how SPARQL deals with RDF Schema and OWL entailment regimes, sub-queries, and insert, update, and delete operations is informative in the sense that it explains the reasons why the changes made in SPARQL 1.1 were necessary.

SPARQL Beyond Subgraph Matching

Abi Evans — Tue, 15 Sep 2015 02:33:08 +0000

This paper describes the extension of the Semantic Web query language SPARQL by defining the semantics of SPARQL queries under the entailment regimes of RDF, RDFS, and OWL. It reviews the conditions that SPARQL
imposes on such extensions, discusses the practical difficulties of this task, and explicates the design choices underlying our proposals. In addition, it includes an overview of current implementations and their underlying techniques.

Simple SPARQL Tutorial: Assigning Values, String Functions .. more on Subqueries

Abi Evans — Thu, 13 Aug 2015 03:26:19 +0000

Building on previous tutorials in the series, this tutorial quickly reviews how to bind properties to variables, then moves on to showing how string functions can be used to perform operations with values from the dataset.

Simple SPARQL Tutorial: Subqueries (Queries Inside Queries)

Abi Evans — Thu, 13 Aug 2015 03:26:18 +0000

Tutorial explaining how the it is possible to nest one query within another query in order to avoid the queries running independently (and thus returning multiple results of the same triples). Shows both the proper syntax for subqueries and explains the rationale (including how they differ from the use of UNION).
