Finding RDF data – Linked Data for Professional Education

Eurostat Linked Data

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

his is a Linked Data version of the Eurostat data with the goal to provide 5 star Linked Open Data on the European level, in a contextually rich and up-to-date manner, useful for ETL-style business analysis or data warehousing purposes with benefits including but not limited to: It allows for a straight-forward comparison of statistical indicators across EU countries; Through providing context for statistics it facilitates the interpretation process; Enables one to re-use observations in a fine-grained way. A SPARQL endpoint allows the user to query the entire metadata, including DSDs and dictionaries. Contains SPARQL queries kindly provided by Søren Roug from the European Environment Agency (EEA).

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.

MeSH RDF Technical Documentation

Tue, 08 Aug 2017 08:07:57 +0000

MeSH RDF is a linked data representation of Medical Subject Headings, a biomedical vocabulary produced by the National Library of Medicine. MeSH RDF includes a downloadable file in N-Triples format, a SPARQL query interface, a SPARQL API, and a RESTful interface for retrieving MeSH data. Includes links to detailed diagrams and explanations of the Data Model, as well as Cheat Sheets for Classes, Predicates, Properties, and SPARQL queries.

Medical Subject Headings (MeSH) RDF Linked Data (beta)

Tue, 08 Aug 2017 08:07:57 +0000

This links to the home page of beta version of the Medical Subject Headings (MeSH) data in RDF (Resource Description Framework). The National Library of Medicine (NLM) is seeking stakeholder input and feedback as part of a broader effort to evaluate the creation of an NLM Linked Data Service. This includes refining MeSH RDF and contributing use cases for future services. Includes links to documentation, a SPARQL endpoint query interface, and a download of the MeSH RDF data.

Desiderata for an authoritative Representation of MeSH in RDF

Tue, 08 Aug 2017 08:07:57 +0000

Although the Semantic Web provides a framework for the integration of resources on the web, datasets are not always made available in RDF by their producers and the Semantic Web community has had to convert some of these datasets to RDF in order for these datasets to participate in the LOD cloud. As a result, the LOD cloud sometimes contains outdated, partial and even inaccurate RDF datasets. The authors of this article review the LOD landscape for one of these resources, MeSH, and analyze the characteristics of six existing representations in order to identify desirable features for an authoritative version, for which they have created a prototype. They then illustrate the suitability of this prototype on three common use cases. NLM released an authoritative representation of MeSH in RDF (beta version) in the Fall of 2014.

Maximising (Re)Usability of Library Metadata Using Linked Data

Sun, 06 Aug 2017 07:58:04 +0000

In this video, the speaker explores challenges related to the re-usability of library linked metadata in the field of cultural heritage- and for other purposes. She argues that it is crucial that published Linked Data accurately represent core aspects of the original metadata related to language, provenance, license, and dataset metadata. The speaker proposes a "proper representation" of these features using W3C standards, best practices and guidelines for multilingual Linked Open Data.

Library Linked Data Incubator Group: Datasets, Value Vocabularies, and Metadata Element Sets

Tue, 23 May 2017 07:03:37 +0000

This report on datasets, value vocabularies and metadata elements sets is a complement to the main report of the Library Linked Data Incubator Group. It contains a set of useful resources for creating or consuming Linked Data in the library domain. In particular, it lists numerous resources for discovering existing Liked Data datasets and RDF vocabularies for reuse. It is intended both for novices seeking an overview of Linked Data focusing on the library domain, and for experts in search of a quick look-up or refresher.

SPARQL Endpoint Probe Service

Tue, 17 Jan 2017 06:46:13 +0000

This is a PHP-based tool for probing statistics about SPARQL endpoints. These include: number of triples stored, number of triples in named graphs, number of unique classes or properties, and class or property frequency. The tool is in experimental stage and subject to change, so please use it with caution.
