Based on the discussion during the DCAT-AP workshop in Rome (13/05/2016), we extracted the following key points:
Transformation tools for mapping: There should be a transformation tool for mapping INSPIRE to DCAT-AP. A tool for serving the need of the public administrations has been developed by GeoDCAT-AP.
Eliminating transformation errors: If developers/users use DCAT-AP from the very beginning, they facilitate the transformation process and eliminates the mapping problems.
DCAT-AP conformance and validation: In Sweden, every public organisation is responsible for providing its metadata in DCAT-AP. The central portal is using unique identifiers for every dataset for the validation. The datasets are validated, and if needed, support is provided to the public organisations to get aligned with the conformance statement.
Validating the validators: DCAT-AP validators are crucial to ensure that the input provided by publishers is correct. However, the participants agreed that the validators themselves should be validated. The input provided by the publishers is crucial, and it should be validated. For the moment, the development of a validator for RDF is in progress.
Training: In order to create well formed, compliant metadata following the DCAT-AP specification, there is the need for providing clear guidelines. E.g. in Sweden, they provide an explanatory editable online form.
Tools repository: For better organising and sharing the available tools, the participants are invited to share their tools, and reuse ones that are available on Joinup. It would be useful to document the tools under specific groups (e.g. authoring environment, validators, harvesting solutions, mapping, transformation and portals).
