Published on

This talk will describe the RAGLD framework (Rapid Assembly of Geo-centred Linked Data) and examples will be given on how it can be used to make it easier to develop linked data applications.

As more linked data and open data emerges a need was identified to meet a rising demand for a suite of application developers’ tools to make it easier to bring together, use and exploit these diverse data sets. RAGLD aims to create a set of tools, components and services to make it easier to develop linked Data applications. This talk will describe the RAGLD framework and examples will be given on how it can be used.

  1. 1. Dr John Goodwin Principal Scientist RAGLD
  2. 2. About RAGLD • A collaborative project between Ordnance Survey, the University of Southampton and Seme4 • Part-funded by the Technology Strategy Board„s “Harnessing Large and Diverse Sources of Data” programme • 18 month long project. Started Oct 2011. Due to complete March 2013 • Building tools to enable developers to make greater use of linked data

  5. 5. As more and more linked data and open data emerges, RAGLD aims to meet rising demand for a suite of application developers‟ tools to make it easier to bring together, use and exploit this diverse data. This project aims to provide the tools, components and services necessary to build linked data applications, helping to speed up and enhance the use of linked data and realise the potential in linked data for data integration and discovery.
