Understands that QNames define shorthand prefixes for long URIs. – Linked Data for Professional Education https://ld4pe.dublincore.org Learning resources tagged by competency Thu, 19 Nov 2020 14:45:03 +0000 en-US hourly 1 https://wordpress.org/?v=4.9.16 A Quick Tutorial on the Turtle RDF Serialization https://ld4pe.dublincore.org/learning_resource/a-quick-tutorial-on-the-turtle-rdf-serialization/ Fri, 27 Jan 2017 06:47:08 +0000 https://ld4pe.dublincore.org/learning_resource/a-quick-tutorial-on-the-turtle-rdf-serialization/ This blog post covers the use of Turtle, which the author describes as "one of the more humane RDF serializations". Turtle is simple to understand, is human readable and editable in its raw form, and is relatively compact. In order to explain the serialization, the author presents the basics of the RDF data model.

]]> prefix.cc: Namespace Lookup for RDF Developers https://ld4pe.dublincore.org/learning_resource/prefix-cc-namespace-lookup-for-rdf-developers/ Thu, 29 Dec 2016 06:44:04 +0000 https://ld4pe.dublincore.org/learning_resource/prefix-cc-namespace-lookup-for-rdf-developers/ The intention of this service is to simplify a common task in the work of RDF developers: remembering and looking up URI prefixes. One can look up prefixes from the search box on the homepage, or directly by typing URLs into a browser bar, such as http://prefix.cc/foaf or http://prefix.cc/foaf,dc,owl.ttl. The service supports over a dozen syntaxes for displaying the prefix mapping. New prefix mappings can be added by anyone. If multiple conflicting URIs are submitted for the same namespace, visitors can vote for the one they consider the best.

It is not intended as an introduction for managers or policy makers. It is primarily aimed at people who are tasked with creating RDF and need information quickly. It is also useful to people who want to work with RDF data.

It provides an easy-to-read list of similarities and differences between RDFa, Microdata and Microformats. A simple table summarizing all features across each structured data syntax is listed, with a link to a brief explanation of the feature.

This lecture discusses the Semantic Web Layer Cake, the relational data model, and distributed data. Introduces the RDF graph model and continues discussion of the role of HTTP URIs, including fragment identifiers and XML QNames. Introduces RDF syntaxes/serializations (N3 and Turtle) and the FOAF Vocabulary.

The subjects covered are namespaces and their technical and semantic functions, including definition, use, examples, and emerging practice. Application profiles are also discussed and examples given.

Based on harvested metadata in RDF (Resource Description Framework), the registry
allows users to explore links between "namespace schemas", which declare standard definitions of metadata terms, and "application profiles" – RDF
statements about the use or adaptation of namespace terms for particular domains, services, or projects.
