Knows the SPARQL 1.1 Graph Store HTTP protocol for updating graphs on a web server (in “restful” style). – Linked Data for Professional Education

Using Semantics with the REST Client API

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

This is the ninth chapter in MarkLogic's "Semantic Developer's Guide". It describes how to use MarkLogic Semantics with the REST Client API to view, query, and modify triples and graphs using REST over HTTP. A MarkLogic SPARQL endpoint is available to use with SPARQL query and SPARQL Update to access triples in MarkLogic. Several types of optimized serialization are available for SPARQL results and RDF triples over REST.

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.

Learning SPARQL: 2nd Edition

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

This book teaches how to use SPARQL 1.1, starting off with simple queries that demonstrate the language using a query-by-example approach and then taking the reader through all the key features of the SPARQL 1.1 query and update languages. All example code is provided for the reader and can be run with open-source software. In addition to the print version, this book is available in EBook, DAISY, ePub, Mobi and PDF formats.

Linked Data Patterns

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

This resource is a pattern catalogue for modelling, publishing, and consuming Linked Data which adopts a tried and tested means of communicating knowledge and experience in software development: the design pattern. The intent is to create a ready reference that will be useful for both the beginner and the experienced practitioner alike. It is also intended to grow and mature in line with the practitioner community. NOTE: This is a book-length resource and covers a wide range of different areas from the design of Web-scale identifiers to application development patterns.

Access Control for HTTP Operations on Linked Data

Abi Evans — Tue, 10 Nov 2015 05:12:58 +0000

Access control is a recognized open issue when interacting with RDF using HTTP methods. In literature, authentication and authorization mechanisms either introduce undesired complexity such as SPARQL and ad-hoc policy languages, or rely on basic access control lists, thus resulting in limited policy expressiveness. This paper attempts to show how the Shi3ld attribute-based authorization framework for SPARQL endpoints has been progressively converted to protect HTTP operations on RDF.

SPARQL 1.1 Graph Store HTTP Protocol

Abi Evans — Mon, 09 Nov 2015 02:49:52 +0000

This W3C Specification describes the use of HTTP operations for the purpose of managing a collection of RDF graphs. This interface is an alternative to the SPARQL 1.1 Update protocol. Most of the operations defined here can be performed using that interface, but for some clients or servers, this interface may be easier to implement or work with. This specification may serve as a non-normative suggestion for HTTP operations on RDF graphs which are managed outside of a SPARQL 1.1 graph store.

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.

Implementing Graph Transformation Languages using RDF Storage and SPARQL Queries

Abi Evans — Fri, 06 Nov 2015 01:49:10 +0000

RDF has so far not been widely used in the context of graph rewriting tools. In this paper, the authors take AToMPM, a research-oriented meta-modelling and graph rewriting tool and extend it by adding RDF-based graph transformation functionality. Addressed is the graph matching problem, generating custom SPARQL queries for each rule pattern, and using them to efficiently perform matches on a source RDF graph.
