RDF XML

Wed, 21 Dec 2016 06:43:13 +0000

Despite the title, this resource covers more territory than simply expressing RDF in the XML serialization. It also gives a basic description of the RDF data model and its purpose, as well as RDF Schema, which provides a framework to describe application-specific classes and properties. Includes lists of RDF/RDFS classes, Properties, and Attributes. Examples show how to express RDF statements in XML (including the reuse of Dublin Core properties).

Introduction to Semantics in MarkLogic

Fri, 15 Apr 2016 23:37:50 +0000

This is the first chapter in MarkLogic's "Semantic Developer's Guide". It contains information about the RDF data model in general but, more importantly, the chapter details how to store and query RDF in MarkLogic. Unique identifiers and namespaces are also discussed. Also included is a list of terms commonly used in the Semantic Web and Linked Data communities, as well as links to several datasets.

An Introduction to the Resource Description Framework

Sat, 10 Oct 2015 12:05:44 +0000

This early article describes the RDF Data Model in its simplest form. Provides introduction, background information, and presents simple RDF syntax. MUCH has happened since this article has been published – observing the evolution of a key Semantic Web standard would likely be this resource's primary use.

Namespaces and Application Profiles

Sun, 04 Oct 2015 05:32:27 +0000

These slides are lectures notes from a unit of the course, "Organization of Information and Resources" which was taught at the University of Washington. 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.

Application Profiles as Machine-Understandable Narratives

Sun, 04 Oct 2015 05:32:27 +0000

The SCHEMAS Registry aims at providing a selected and annotated overview of metadata vocabularies and their use in application environments. 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.

Semantic Web Tutorial 9/14: RDF Schema and OWL 1/4

Wed, 30 Sep 2015 22:30:59 +0000

Video tutorial describing the role of vocabularies in Semantic Web development, particularly the reuse of existing vocabularies. How to access predefined classes and properties through a vocabulary's namespace. Uses an example showing how RDF Schema can be used to describe Dublin Core metadata terms. One in a series of related videos.

Introducing RDF/XML

Thu, 13 Aug 2015 13:45:21 +0000

After this tutorial, you should be able to: 1) Formally understand RDF statements, including objects as resources and literals; 2) Write basic RDF documents in RDF/XML; 3) Understand how RDF identifies resources using URIs; 4) Understand why RDF is ideal for what it is built for- exchanging informationglobally.

Best Practice Recipes for Publishing RDF Vocabularies

Thu, 13 Aug 2015 03:26:17 +0000

This document describes best practice recipes for publishing an RDF Schema or OWL vocabulary or ontology on the Web. The features of each recipe are clearly described, so that vocabulary or ontology creators may choose the recipe best suited to the needs of their particular situations. Each recipe contains an example configuration for use with an Apache HTTP server, although the principles involved may be adapted to other environments. The recipes are all designed to be consistent with the architecture of the Web as currently specified.
