Understands that the properties of hierarchical subsumption within an RDF vocabulary — rdfs:subPropertyOf and rdfs:subClassOf — can also be used to express mappings between vocabularies. – Linked Data for Professional Education

RDFS for Hierarchy and Subsumption

Sun, 02 Apr 2017 06:55:49 +0000

This PowerPoint presentation explains the role which concepts from thesauri and taxonomies play in Linked Data (especially as they relate to SKOS). It briefly discusses ontologies in general before moving on to RDF Schema. Examples are given of how to defines classes of resources and the relations that connect them using RDFS. Focuses on defining hierarchical relations in support of inference (i.e., formally stating that membership in a narrower class automatically implies membership in a broader class).

How to (Properly) Publish a Vocabulary or Ontology On the Web, Part 6

Wed, 21 Dec 2016 06:43:12 +0000

This resource contains a set of guidelines on how to reuse other vocabularies (i.e., how one's vocabulary should link to other vocabularies). Reuse is not only related to publication, but also to the design of a vocabulary. Discusses the relative benefits of either importing another vocabulary into one's own vocabulary, or extending only those properties and classes that one is going to reuse, without adding all of the terms of the other vocabulary. Includes a short list of resources for finding RDF vocabularies for reuse.

Tutorial on Metadata Provenance

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

This two-part slide presentation was used at the Semantic Web in Libraries (SWIB) Conference. "Part 1: Linked Data Provenance" answers the questions, "How can we identify RDF data, statements within RDF data, Linked Data, … in order to provide provenance?". "Part 2: The PROV Ontology" addresses, "How can we represent the provenance of resources?".

Model Driven Engineering for Publishing Data on the Semantic Web

Abi Evans — Sat, 10 Oct 2015 12:05:44 +0000

Publishing local data on the Semantic Web requires that one provide a shareable semantic data representation of that data. This paper presents a complete Model Driven Engineering (MDE) approach that allows for importing data sources into an RDF repository. First, the object domain model is mapped to an ontology and to a persistence model through annotation performed by a domain expert. Then, all other processes are automated and data transformations are generated from the mappings via model-weaving techniques.

The Vocabulary Mapping Framework (VMF): An Introduction v1.0

Abi Evans — Sat, 10 Oct 2015 12:05:44 +0000

This document provides an introduction to the structure and development of the Vocabulary Mapping Framework (VMF) up to the end of the first stage of this work in November 2009. The document is in two parts: an overview and a technical description. Near the end, candidate mappings between Onix Code List 17 and the Marc 21 “Relationship” vocabularies are shown. The SPARQL queries used to derive the mappings are shown following.

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.
