Linked Data Project - Introduction

The Mimas Linked Data Project is a JISC funded project which was part of the jiscEXPO programme.

“jiscEXPO” represents two things: (1) the “Joint Information Systems Committee” (JISC) which is the funding organisation behind this set of projects, and (2) “EXPOsing” of content as linked data. The funding has been used to expose a subset of data for:

  • Landmap Service
  • Economic and Social Data Service (ESDS)

Project updates and further information about the team can be found in The Mimas Linked Data Project Blog

The following sections focus on the work the Landmap Service has achieved.

Landmap Aims and Objectives

A key aim was to create awareness and understanding of Linked Data within the Landmap team and to explore the wider benefits Linked Spatial Metadata will have for the service and its’ end users. The objectives are:

  • To create capacity and to up-skill staff within Landmap on Linked Data
  • Create linked spatial metadata for a subset of the Landmap datasets
    • Building Class
    • Building Heights
    • Thermal Images
  • Have an understanding of future resources requirements for developing Linked spatial metadata within Landmap

Landmap Achievements

  • Knowledge gained regarding developing linked data
  • Vocabularies identified
  • In the early stages of the project a few sample RDF files were created from Landmap spatial metadata using JAXP and XSL. However due to the spatial metadata XML's being deeply nested, it was necessary to use the extensive and rich Java based JENA framework for the RDF conversion; this technique was applied to the Building Class, Building Heights and Thermal metadata with the resultant RDF files now available for download.
  • Explained within the wider academic community the significance of the information rich Landmap spatial metadata being provided as Linked Data e.g. at the 2011 INSPIRE Conference
  • Formed networks and key contacts within the wider academic community, to gain more knowledge on creating the ISO standard metadata into RDF
  • Aware of potential opportunities for future collaborations between the Landmap service and other organizations/data providers working on linked data
  • Data model defined

Next Steps

The next steps for future work depending on funding will be:
  • To publish the RDF which requires:
    • Mimas linked data triple store database
    • SPARQL endpoint
    • Establish synergies and relationships between Landmap linked data and other services/data providers
    • Extend knowledge in Landmap of describing relationships technically for the linked data by attending Web Ontology Language (OWL) training
