I had a few outstanding questions to answer on the ontology.
Hereunder you find the answers. I also include as attachment the
* field Accrual Periodicity
the correct label name on the EU ODP portal.
* temporal granularity:
no RDF field in the ontology
* Catalog record - publication dates
The next fields are publisher controlled:
Publisher controlled means:
* RDF2CKAN can set the value of these fields
* CKAN web interface allows to set these fields
In DCAT-AP, they correspond to the dataset properties having the next
(a) date of formal issuance (e.g. publication) of the dataset
(b) the most recent date on which the dataset was changed, modified
The Catalog record fields, shown as
(c) Added to open-data.europa.eu
(d) Updated on open-data.europa.eu
in the EU ODP portal (see dataset Additional information)
are created by CKAN, the catalog owner. They cannot be set by RDF2CKAN.
In DCAT-AP, they correspond to the catalog record properties having
the next definition:
(c) The date of listing the corresponding dataset into the catalog
(d) Most recent data on which the catalog entru was changed,
updated or modified.
Technical challenge is to do an efficient integration of these catalog
record fields in the RDF created by the RDF2CKAN ingestion.
These fields are, by definition, not part of the RDF provided by the publishers.
