SPARQL Update

Sun, 17 Apr 2016 23:37:58 +0000

This is the eighth chapter in MarkLogic's "Semantic Developer's Guide". It explains that SPARQL Update enables you to manipulate triples or sets of triples. Within MarkLogic, one can also manage security levels using SPARQL Update. All SPARQL queries over managed triples are governed by the graph permissions. Triple documents will inherit those permissions at ingest.

Semantic Inferencing with MarkLogic

Sat, 16 Jan 2016 13:43:28 +0000

This tutorial familiarizes the user with concepts and steps for using Semantic Inferencing in MarkLogic. The concepts of inference, rulesets, asserted triples and ontology triples are described with examples. Forward and backward chaining is compared and contrasted. RDF Schema, OWL, and path-based inference are also described and demonstrated. Includes discussion of best practices for optimizing inference performance.

Module 2: Querying Linked Data

Abi Evans — Sat, 07 Nov 2015 02:03:58 +0000

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.

Updating RDFS ABoxes and TBoxes in SPARQL

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

Updates in RDF stores have recently been standardized in the SPARQL 1.1 Update specification. However, computing answers entailed by ontologies in triple stores is usually treated orthogonal to updates. Even SPARQL 1.1 Update language and SPARQL 1.1 Entailment Regimes specifications explicitly exclude a standard behavior about how SPARQL endpoints should treat entailment regimes other than simple entailment in the context of updates. In this paper, the authors take a first step to close this gap by discussing possible semantics along with potential strategies for implementing them.
