Welcome to Inspire2RDF: A suite of tools for exposing INSPIRE metadata and data as linked data¶
Introduction¶
- Introductory slides: https://web.imis.athena-innovation.gr/redmine/attachments/download/2218/GeoKnow_AthenaRC_INSPIRE2015.pdf
as presented at the INSPIRE Conference - Geospatial World Forum 2015: http://geospatialworldforum.org/workshop.asp?Sp_Department=INSPIRE%20Linked%20Data
Software Resources for testing¶
- HUMBOLDT Alignments to INSPIRE for datasets from geodata.gov.gr: https://web.imis.athena-innovation.gr/redmine/attachments/download/1858/HUMBOLDT_Alignments_GR.zip
- XSL stylesheets for converting INSPIRE-aligned GML DATA into RDF/XML (conforming to GeoSPARQL specifications for geometries) for seven INSPIRE Data Themes (Annex I):
https://web.imis.athena-innovation.gr/redmine/attachments/download/1882/INSPIRE2RDF_Data_Annex_I_XSLT.zip
You can edit any of these files in order to prepare suitable configuration settings for converting another geospatial dataset into its GeoSPARQL-compliant RDF representation.

- Transforming INSPIRE-aligned data and metadata into RDF can be performed through TripleGeo utility, using suitably configured XSL stylesheets. The Java source code for TripleGeo is freely available from https://github.com/GeoKnow/TripleGeo.
- Querying INSPIRE-compliant Catalogue Services for the Web (CSW) using SPARQL can be performed with the TripleGeo-CSW utility. The python source code for TripleGeo-CSW is freely available from https://github.com/GeoKnow/TripleGeo-CSW.
