What Landmap set out to achieve?
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 resource requirements for developing Linked spatial metadata within Landmap
What Landmap achieved?
- Knowledge gained regarding developing linked data
- Vocabularies identified:
- Sample RDF files created for Building Class data and Thermal data using JAXP (Java API for XML Processing) and XSL. Also Java based Jena framework has been considered for creating linked data.
- Explained within the wider academic community the significance of the information rich Landmap spatial metadata being provided as Linked Data.
- 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.
Final Work Plan is
|Task Number||Task||Dependency/Constraint||Proposed Start Date||Proposed End Date|
|1||URI Creation||Might take extra time||06/10/11||07/10/11|
|RDF Creation||– Data issues
– Code optimization
|Interface Creation||Code compatibility||26/10/11||28/10/11|
Beyond RDF Creation
On completion of this project a sample of RDF files will have been created. 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 OWL training
