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.

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.

Provenance and Annotations for Linked Data

Wed, 23 Nov 2016 05:50:22 +0000

Provenance tracking for Linked Data requires the identification of Linked Data resources. Annotating Linked Data on the level of single statements requires the identification of these statements. The author introduces the concept of a "Provenance Context" as the basis for a consistent data model for Linked Data that incorporates current best-practices and creates an identity for every published Linked Dataset. A comparison of this model with the Dublin Core Abstract Model is provided to gain further understanding of how Linked Data affects the traditional view on metadata and to what extent our approach could help to mediate. Finally, a linking mechanism based on RDF reification is developed to annotate single statements within a Provenance Context.

Providing Linked Data

Sun, 23 Oct 2016 05:39:27 +0000

This module covers the whole spectrum of Linked Data production and exposure. After a grounding in the Linked Data principles and best practices, with special emphasis on the VoID vocabulary, it covers R2RML, operating on relational databases, Open Refine, operating on spreadsheets, and GATECloud, operating on natural language. Finally it describes the means to increase interlinkage between datasets, especially the use of tools like Silk.

Adoption of Linked Data Best Practices in Different Topical Domains

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

The central idea of Linked Data is that data publishers support applications in discovering and integrating data by complying to a set of best practices in the areas of linking, vocabulary usage, and metadata provision. This paper revisits and updates the findings of the 2011 State of the LOD Cloud report based on a crawl of the Web of Linked Data conducted in April 2014.

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.

Linked Data Life Cycles, Part 3

Abi Evans — Thu, 13 Aug 2015 13:45:22 +0000

Based on the author's experience in Linked Data publishing and consumption over the past years, he has identified involved parties and fundamental phases, which provide for a multitude of "Linked Data Life Cycles". This lecture finishes the description of the last three stages the Linked Data Life Cycle: 4) Discovery; 5) Integration; 6) Use Cases. The first three stages, as well as Linked Data principles in general, were described in the previous two videos.
