AGLS Metadata Standard Guide to expressing AGLS metadata in RDF - in pdf format (938kb)
- (This document requires the use of Adobe Acrobat Reader). National Archives of Australia, Version 1.0, July 2010. "The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. It is particularly intended for representing metadata such as the title, author and creation date of a resource, copyright and licensing, or the availability a shared resource. RDF can also be used to represent information about things that can be identified online even if they are only available offline. This document provides guidelines for expressing AGLS metadata using RDF. This Guide is for use with AGLS Metadata Standard Part 1: Reference Description, which explains the semantics of the AGLS properties, and AGLS Metadata Standard: Guide to expressing AGLS metadata in XML, which explains the XML syntax of AGLS properties. AGLS Metadata Standard Part 2: Usage Guide gives a general overview of AGLS implementation, includes information about certain business issues that need to be resolved when making a decision to implement AGLS metadata, and examples in HTML and XHTML. This document assumes a basic knowledge of the concepts of eXtensible Markup Language (XML) and RDF and is intended for those familiar with XML/RDF and wishing to implement AGLS..."

How to Embed YouTube Videos with Valid RDFa Markup
- by John S. Britsios, SEO workers, July 31, 2010. "The techniques explained in this tutorial are fully supported by Google and Yahoo, and can boost your video's visibility in their search results! YouTube videos have worked their way into a prominent position as a tool for both content and SEO, in websites from all over the world. The convenience of being able to embed a video on webpages has given such media an important place in the marketing strategies of many sites..."

The Data-gov Wiki
- Tetherless World Constellation, Rensselaer Polytechnic Institute (RPI). "The Data-gov Wiki is a project being pursued in the Tetherless World Constellation at Rensselaer Polytechnic Institute. We are investigating open government datasets using semantic web technologies. Currently, we are translating such datasets into RDF, getting them linked to the linked data cloud, and developing interesting applications and demos on linked government data. Most of the datasets shown on this page come from the US government's data.gov Web site, although some are from other countries or non-government sources..."

RDFa Primer: Bridging the Human and Data Webs
- W3C Working Group Note 14 October 2008. "Abstract - Today's web is built predominantly for human consumption. Even as machine-readable data begins to appear on the web, it is typically distributed in a separate file, with a separate format, and very limited correspondence between the human and machine versions. As a result, web browsers can provide only minimal assistance to humans in parsing and processing web data: browsers only see presentation information. We introduce RDFa, which provides a set of XHTML attributes to augment visual data with machine-readable hints. We show how to express simple and more complex datasets using RDFa, and in particular how to turn the existing human-visible text and links into machine-readable data without repeating content..."

Introduction to RDFa II
- by Mark Birbeck. A List Apart Magazine, July 7, 2009. "... In part II, we'll learn how to add properties to an image, and how to add metadata to any item — and we'll add a few more rules to that list..."

Introduction to RDFa
- by Mark Birbeck. A List Apart Magazine, 23 June 2009. "RDFa (Resource Description Framework in attributes) is having its five minutes of fame: Google is beginning to process RDFa and Microformats as it indexes websites, using the parsed data to enhance the display of search results with 'rich snippets'. Yahoo!, meanwhile, has been processing RDFa for about a year. With these two giants of search on the same trajectory, a new kind of web is closer than ever before..."

Cool URIs for the Semantic Web
- W3C Working Draft 21 March 2008. "Abstract - The Resource Description Framework RDF allows users to describe both Web documents and concepts from the real world—people, organisations, topics, things—in a computer-processable way. Publishing such descriptions on the Web creates the Semantic Web. URIs (Uniform Resource Identifiers) are very important, providing both the core of the framework itself and the link between RDF and the Web. This document presents guidelines for their effective use. It discusses two strategies, called 303 URIs and hash URIs. It gives pointers to several Web sites that use these solutions, and briefly discusses why several other proposals have problems..."

RDFa Primer - Embedding Structured Data in Web Pages
- W3C Working Draft 17 March 2008. "Abstract - The modern Web is made up of an enormous number of documents that have been created using HTML. These documents contain significant amounts of structured data, which is largely unavailable to tools and applications. When publishers can express this data more completely, and when tools can read it, a new world of user functionality becomes available, letting users transfer structured data between applications and web sites, and allowing browsing applications to improve the user experience: an event on a web page can be directly imported into a user's desktop calendar; a license on a document can be detected so that users can be informed of their rights automatically; a photo's creator, camera setting information, resolution, location and topic can be published as easily as the original photo itself, enabling structured search and sharing. RDFa is a specification for attributes to be used with languages such as HTML and XHTML to express structured data..."

Best Practice Recipes for Publishing RDF Vocabularies
- W3C, 29 January 2008. "The Semantic Web Deployment Working Group has published the Working Draft of Best Practice Recipes for Publishing RDF Vocabularies. This document describes best practice recipes for publishing vocabularies or ontologies on the Web (in RDF Schema or OWL). Each recipe introduces general principles and an example configuration for use with an Apache HTTP server (which may be adapted to other environments). The recipes are all designed to be consistent with the architecture of the Web as currently specified..."

RDF For The Rest Of Us
- By Keith Alexander. Digital Web Magazine, July 30, 2007. "...RDF is the core language of the Semantic Web. What this means is that, by publishing your data as RDF on the web, by using terms from existing vocabularies where you can, and by linking to other data, you can increase the usefulness of both the data you link to, and your own..."

RDFa Primer: Working Draft
- W3C, 13 March 2007. "The XHTML2 Working Group and the Semantic Web Deployment Working Group jointly have published an updated Working Draft of the RDFa Primer 1.0. RDFa expresses metadata in XHTML-compatible constructs and extensions, enabling a new world of user functionality. The draft is a companion to the XHTML 2.0 specification. Changes include new syntax for striping and use of the class attribute to declare rdf:type..."

Note: RDF/Topic Maps Interoperability
- W3C, 10 February 2006. "The Semantic Web Best Practices and Deployment Working Group has published A Survey of RDF/Topic Maps Interoperability Proposals as a Working Group Note. The Note records existing proposals for integrating data represented in W3C's RDF/OWL family of languages with data represented in ISO's Topic Maps. It is a starting point for establishing guidelines for combined usage of these standards, assuring interoperability."
