Rww. Linked Data at the Guardian. The semantic web is given a rough raking by the syntactic web, and it is not impossible to see why when you first get taken down the SPARQL/RDF/Ontology rabbit hole.
It is not great fun learning to develop with the semantic web today. (As an aside, using a semi-SQL model as a primary metaphor in SPARQL did not help me personally. Linked Data FAQ. Linked data is the first practical expression of the semantic Web, useful and doable today, and applicable to all forms of data.
Sources such as the four principles of linked data in Tim Berners-Lee's Design Issues: Linked Data and the introductory statements on the linked data Wikipedia entry approximate -- but do not completely express -- an accepted or formal or official definition of linked data per se. Building from these sources and attempting to be more precise, here is the definition of linked data used internally by Structured Dynamics: L’intérêt de l’OpenApi pour les entreprises. Young Lives Linked Data Demonstrator : Tim's Blog. [Summary: showcasing linked data for development project] Over the past month or so I’ve been working for IKM Emergent on a demonstrator project to explore the potential implications of linked data for information management in the development sector – seeking put a small sub-section of the survey micro-data from the Young Lives longitudinal study online in order to explore the process and potential of generating linked data in development-focussed settings.
The results of that project are now live and online for the time being, and accessible here. The most visually interesting part of the demonstrator (thanks to the work or Rupert Redington at NeonTribe) is the Comparator tool which does some pretty clever things to identify ‘Data Cubes’ in the Young Lives linked data dataset we’ve published, and to offer (in the case of the smoking prevalence data) comparisons between the Young Lives dataset, and another comparable dataset we’ve also loaded into our Young Lives datastore.

Virtuoso Linked Data Deployment In 3 Simple Steps. Injecting Linked Data into the Web has been a major pain point for those who seek personal, service, or organization-specific variants of DBpedia.
Basically, the sequence goes something like this: You encounter DBpedia or the LOD Cloud Pictorial. You look around (typically following your nose from link to link).

Whether or not linked data is the 'next big thing' in web technology, and one that has to potential to solve a number of thorny problems for the administrators and maintainers of web resources in the face of increasingly complex demands, is a question that only time will answer. Veille Oct. II « What is Data Quality? There are several different opinions and definitions on what data quality is supposed to be.
Most of the time, we adapt the “fitness for use by data consumers” definition as defined by Richard Wang and Diane Strong  who investigated the subjective quality perception of data quality by data consumers. Although this research work has been a milestone in data quality research, in my opinion data quality is not necessarily always subjective. Imagine valid combinations of cities and countries or accurate population values. So what can I do with the new Ordnance Survey Linked Data? « John’s Weblog. In a previous post I wrote up some of the features of the new Ordnance Survey Linked Data.
In this blog post I want to run through a concrete example of the sort of thing you can build using this linked data. A while ago Talis built their BIS Explorer. The aim of this application was to allow users to “identify centres of excellence at the click of a button” and more can be read about the application here. This data mash-up took different data sources about funded research projects and joined them together using linked data. In the original application you could, for example, look at funded research projects by European Region in Great Britain.
