VoID Dataset
Extractor, provides a form to fill in VoID Dataset metadata properties.
- Get distribution IRI from input
- Gets distribution IRI from input, output of DCAT-AP Distribution is expected.
- Distribution IRI
- When used independently, distribution IRI can be set here.
- Example resource URLs
- URLs of example resources.
- SPARQL Endpoint URL
- URL of a SPARQL endpoint through which the data is accessible.
- Copy download URLs to
void:dataDump - In DCAT, the link to download a file is
dcat:downloadURL. This copies it also tovoid:dataDumpfor VoID enabled applications.

The VoID Dataset component provides a form to fill in VoID Dataset metadata. The typical usage is in each data preparation pipeline to store and produce distribution related metadata. Though the exact relation of DCAT-AP Distribution and VoID Dataset is not defined, for our purposes we say that for RDF distributions of datasets, they are the same. Therefore, the expected usage is that the IRI of the DCAT-AP distribution describing RDF data is the same as the IRI of the VoID dataset. So far, we support only limited number of VoID properties wiht focus on catalogization in CKAN. It can use the output of the DCAT-AP Distribution component to reuse the Distribution IRI and download URLs. Its output can be used by the DCAT-AP to CKAN component for loading the metadata into CKAN.
