BIBFRAME Training at the Library of Congress: Introduction to the Semantic Web and Linked Data

Fri, 19 May 2017 07:03:10 +0000

This resource was developed by the Library of Congress as one part of a pilot training project which tested the use of BIBFRAME for bibliographic description. The purpose of this module is to introduce the Semantic Web, Linked Data concepts, and some basic tools. Topics covered include the role of semantically linked data in creating useful web services and connecting datasets on the web. The limits of the current MARC based environment are contrasted with the promise of integrating data more fully with Semantic Web resources to enhance user services. This home page contains links to PowerPoint presentations, quizzes, and assignments.

The Semantic Web and Linked Data Concepts: The RDF Data Model and Linked Open Data (LOD) Quiz

Fri, 19 May 2017 07:03:10 +0000

This quiz covers material presented in the first module of the BIBFRAME pilot training project at the Library of Congress. The quiz consists of five multiple choice questions with the answers explained in popups after the user has made their selection. Questions address possible misconceptions regarding Linked Data principles and Linked Open Data (LOD), as well as the role of the RDF data model, triple statements, and vocabularies within the Semantic Web.

The Semantic Web and Linked Data Concepts: The RDF Data Model and Linked Open Data (LOD)

Fri, 19 May 2017 07:03:10 +0000

This PowerPoint presentation was used during the "Introduction to the Semantic Web and Linked Data" module of the pilot training project developed by the Library of Congress which tested the use of BIBFRAME for bibliographic description. This presentation explains the RDF data model, the use of URIs to identify resources, and other RDF "tools". BIBFRAME is discussed as one of many vocabularies and ontologies being used to describe relationships between resources on the Semantic Web. The wider concept of Linked Open Data (LOD) is introduced along the principles and practices that support it. The module's home page contains links to more materials.

What's a URI and Why Does It Matter?

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

This brief article introduces the terminology and issues surrounding URIs and their role on the Web. This includes some historical context of what URI originally meant, as well as the ways it is used now and the direction in which it seems to be evolving. A key point is made regarding the difference between resources and their representations.

thing-described-by.org

Sat, 14 Jan 2017 06:46:01 +0000

Thing-described-by.org is a 303-redirect service. It provides a convenient mechanism for minting dereferenceable http URIs for things that are not necessarily web resources, such as people, cars or concepts in an ontology.

The Difference Between URLs and URIs

Thu, 29 Dec 2016 06:44:05 +0000

In this blog post, the author succinctly explains the difference between two terms that are often used interchangeably, but are actually different ways to identify resources. Authoritative references are cited to support the author's explanation, and several examples are shown.

Linked Data Basics for Techies

Thu, 29 Dec 2016 06:44:04 +0000

This guide is intended to be a crash course for a techie/programmer who needs to learn the basics ASAP. 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.

RDFa 1.1 Primer – Third Edition

Thu, 24 Nov 2016 05:51:18 +0000

Search engines have begun to provide richer search results by extracting structured details from the Web pages they crawl and, in turn, Web publishers are producing more structured data within their content to improve their standing with search engines. A key enabling technology behind these developments is the ability to add structured data to HTML pages directly using RDFa (Resource Description Framework in Attributes). This Primer shows how to express data in HTML using RDFa and, in particular, how to mark up existing human-readable Web page content to express machine-readable data.
