Managing identifiers (URI) – Linked Data for Professional Education

URI design for RDF conversion of CSV-based data

Fri, 18 Aug 2017 08:22:56 +0000

The sharing of comma-separated files is very common, and a common set of problems arise upon the receipt and processing of data within this format. The RDF vocabulary described in this document provides interpretation instructions to a tool that converts tabular based data into RDF appropriate for linked data publishing. Links to a page which describes a Java-based tool that follows the interpretation vocabulary described here and provides a set of shell script tools to facilitate automatic conversion.

Linked Data for Libraries, Archives and Museums: How to clean, link and publish your metadata

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

This handbook teaches how to unlock the value of existing metadata through cleaning, reconciliation, enrichment and linking, as well as how to streamline the process of new metadata creation. It introduces the key concepts related to metadata standards and Linked Data and how they can be practically applied to existing metadata. Chapters are dedicated to modeling, cleaning, reconciling, enriching, and publishing one's data.

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.
