Understands that to be “persistent”, a URI must have a stable, well-documented meaning and be plausibly intended to identify a given resource in perpetuity. – Linked Data for Professional Education

Linking Lives: Creating an End-User Interface Using Linked Data

Mon, 22 May 2017 07:03:30 +0000

This article describes how LOCAH, a JISC-funded project working to make data from the Archives Hub available as Linked Data, continued on in a new form as "Linking Lives". Biographical data is presented on pages which are populated entirely by Linked Data from various authoritative sources (e.g., VIAF, DBpedia). One challenge faced involved data collection via the application' server vs client's web browse. Another was whether to reconcile of multiple source URIs via creation and persistence of a new URI or to map multiple URIs using the "owl:sameAs property".

Designing URI Sets for the UK Public Sector

Tue, 10 Jan 2017 06:45:33 +0000

This document defines the design considerations and guidance by which UK public sector Universal Resource Identifier (URI) sets should be developed and maintained. They are designed both to encourage those that definitively own reference data to make it available for re-use, and to give those that have data that could be linked, the confidence to re-use a URI set that is not under their direct control.

Is Your Linked Data Vocabulary 5-Star?

Thu, 22 Dec 2016 06:43:15 +0000

This blog post argues that is is not enough just to publish one's Linked Data datasets according to a set of best practices, it is also necessary to make sure that the vocabulary the dataset uses, including its RDF Schema and OWL classes and properties, are also published according to community-accepted standards. Just because datasets share the common RDF data model, there is no guarantee that others can reliably make sense of their semantics in the absence of such standards. To solve this problem, the author suggests his own 5-Star rating system for Linked Data vocabularies.

Permanent Identifiers and Vocabulary Publication: purl.org and w3id

Thu, 22 Dec 2016 06:43:15 +0000

This blog post addresses concerns with the stability of purl for hosting permanent URIs. As a possible alternative, the author presents w3id.org, an effort launched by the W3C permanent identifier community group that has been adopted by a great part of the community and is supported by several companies.

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.

Semantic Technologies: Motivation and Standards

Abi Evans — Tue, 10 Nov 2015 05:13:00 +0000

This lecture covers a lot of topics. It hits all the basic standards and technologies in the Semantic Web stack: the RDF data model, SPARQL, RDF Schema, and OWL- however, none in great depth. However, the focus is placed on how these technologies sit on top of the Web infrastructure which is already in place. HyperText Transport Protocol (HTTP) is discussed in detail.

Providing Linked Data

Abi Evans — Tue, 15 Sep 2015 02:33:09 +0000

This video presentation covers the whole spectrum of Linked Data production and exposure. It begins with a grounding in Linked Data principles and best practices, with special emphasis on the VoID vocabulary. It then covers R2RML (for operating on relational databases), Open Refine (for operating on spreadsheets), and GATECloud (for operating on natural language). Finally, the presentation describes means to increase inter-linkage between datasets, focusing on tools like Silk. NOTE: This a three-part lecture, with all three videos hosted at the same URL. These videos represent material from several lessons that comprised a larger "module" of the EUCLID Project. As such, they cover a wider range of topics than most resources.
