This is the fourth in a series of posts (previously: part 1 , part 2 , part 3 ) on making a thesaurus available as linked data using the SKOS and SKOS-XL RDF vocabularies . In the previous post, I examined some of the ways the thesaurus can change over time, and problems that arose with my proposed mapping to RDF. Here I'll outline one potential solution to those problems. The last three cases I described in the previous post, where an existing preferred term loses that status and is "relegated" to a non-preferred term, all present a problem for my suggested simple mapping, because the URI for a concept disappears from the generated RDF graph - and this creates a conflict with the principles of URI stability and reliability I advocated at the start of that post. My first thoughts on a solution circled around generating concept URIs, not just for the preferred term, but also for all the non-preferred terms, and using owl:sameAs (or skos:exactMatch ?)

Extensible use of RDF in a Business Context
The next generation of intranets should facilitate the structuring of information as well as the organising of communication in networking organisations. For many organisations, one step in that direction is to structure information by adding metadata. We have encountered problems when applying Dublin Core, a metadata element set developed for discovery of existing information resources on the public Internet, on an extensive intranet. Our conclusion, argued in this paper, is that these problems are a consequence of trying to describe information resources without taking into account the context in which end users create and consume information.
The RDF Database Market—Clark & Parsia: Thinking Clearly
Update: Stardog is our entry into the commercial RDF database market. There’s plenty of talk about the purely technical aspects of RDF databases but considerably less talk about the RDF database market as a commercial software business. As I see it, the commercial RDF database market contains at least seven systems, listed here in random order: There are another 8 to 10 technically viable RDF databases available .

Web standards & guidelines Structuring information on the Web for re-usability: Consultations and Job Vacancies Introduction to linked data The Web, in its most basic sense, is a collection of pages linked together via hyperlinks. These documents can contain any number of paragraphs, headings, lists, images and so on.
The concept of Linked Data has largely been the domain of academics and geeks. But this is a new time and space for the Web and the possible uses of Linked Data are becoming more widely recognized. To illustrate the concept of Linked Data, Richard Cyganiak and Anja Jentzsch created the Linked Data Diagram of the Cloud .
The Growth of Linked Data - ReadWriteCloud
I’ve been doing a few talks recently – most recently at the somewhat confused OKCon (Open Knowledge) Conference. The audience was extremely diverse and so I tried to not only talk about what we’ve done but also introduce the concept of Linked Data and explain what it is. Linked Data is a grassroots project to use web technologies to expose data on the web. It is for many people synonymous with the semantic web – and while this isn’t quite true. It does, as far as I’m concerned, represent a very large subset of the semantic web project. Interestingly, it can also be thought of as the ‘ the web done right ’, the web as it was originally designed to be.

I've been working a lot with our repository and Linked Data teams (thanks to Hugh Glaser, Nick Gibbins and Iain Millard) on the JISC dotAC project. One of the great things about that project has been the opportunity to really get our heads around the role of repositories in the Semantic Web and the Linked data world. Now that the project has finished, I've finally had the opportunity to sit down with Chris Gutteridge and braindump our understanding so far. The following is a description of how EPrints (v3.2 beta) exports its holdings as Linked Data. It all comes down to how it uses and resolves URIs.
How Repositories Can Contribute Linked Data
This document provides a tutorial on how to publish Linked Data on the Web. After a general overview of the concept of Linked Data, we describe several practical recipes for publishing information as Linked Data on the Web. This tutorial has been superseeded by the book Linked Data: Evolving the Web into a Global Data Space written by Tom Heath and Christian Bizer. This tutorial was published in 2007 and is still online for historical reasons.
How to publish Linked Data on the Web
Linked Data is about using the Web to connect related data that wasn't previously linked, or using the Web to lower the barriers to linking data currently linked using other methods. More specifically, Wikipedia defines Linked Data as "a term used to describe a recommended best practice for exposing, sharing, and connecting pieces of data , information , and knowledge on the Semantic Web using URIs and RDF ."
