INSPIRE conformant data sharing underpins the implementation of the INSPIRE Directive and is essential for the re-use of INSPIRE data for several purposes and in different policy areas, in accordance to the “once only” principle of the e-Government Action Plan. The validation of INSPIRE data, therefore, plays an essential role in the overall INSPIRE harmonisation process. Most data validation tools provide a mere validation against requirements of the encoding schema, but INSPIRE data validation concept goes far beyond this and shall be based on the Abstract Test Suite (ATS), the set of abstract tests included in the Annex A of the INSPIRE Data Specifications. The eENVplus Validation Service is an online tool for assessing conformance of INSPIRE Annex I, II, III GML datasets, thoroughly used by several EU projects, National public authorities and private organizations. It is based on the OGC ‘GML 3.2 (ISO 19136:2007) Conformance Test Suite’ developed as part of the Open Geospatial Consortium Compliance Program (CITE) and provides: • Schema validation: every dataset is validated against all referenced application schemas requirements. Moreover, the referenced schemas themselves are validated as well. • GML 3.2.1 validation: the dataset is validated against requirements of the ISO 19136 (2007) GML standard, including both the schema requirements and other constraints stemming from standards referenced in the ISO 19136, such as the ISO 19107. • ‘INSPIRE data theme-specific’ validation: validation by means of schematron files of the constraints which cannot be expressed by means of the XML schema grammar (i.e. xsd schemas) such as those concerned with geometries, code lists values and CRS.

In addition, the eENVplus Validation Service empowers validation of any GML data against their application schemas and other specific constraints expressed through schematron files. This feature is particularly beneficial for the thematic communities referencing INSPIRE, such as GeoSciML and AQD, for which the eENVplus Validation service makes available online the official schematrons developed by relevant community experts.

The same benefits are available for the communities developing INSPIRE-extended schemas, who, thanks to the eENVplus Validation Service, can validate the schemas as well as the relevant harmonised datasets.
