CIM WG Maintenance Request - Support DCAT3 about energy-reference-data HOT 4 OPEN

Must update the Header and metadata list.xlsx (entsoe.eu)

from energy-reference-data.

For the item:

Should consider changing the following from String to stringIRI and it shall be serialized as literal.
dcterms:license
dcterms:rights
dcterms:rightHolder

DIGIN is proposing the following:

    "dcterms:rights": "© 2023 Copyright",
    "dcterms:rightsHolder": "DIGIN",
    "dcterms:license": {
        "@id": "https://creativecommons.org/licenses/by-nc-sa/4.0/",
        "dcterms:title": "CC BY-NC-SA 4.0"
    },

Since JSON-LD support compound we can include both the "dcterms:title": "CC BY-NC-SA 4.0" and "@id": "https://creativecommons.org/licenses/by-nc-sa/4.0/"

dcterms:license could be exchange as:

    <dcterms:license>
      <rdf:Description rdf:about="https://creativecommons.org/licenses/by-nc-sa/4.0/">
        <dcterms:title rdf:datatype="http://www.w3.org/2001/XMLSchema#string">CC BY-NC-SA 4.0</dcterms:title>
      </rdf:Description>
    </dcterms:license>

I propose that we have String for rights and rightsHolder and stringIRII for License and we only include the URI.

from energy-reference-data.

DCAT3 recommendation is to use IRI, witch can tehn be URN or URL. This would mean:

1. In case of open licence, use URL defined here https://creativecommons.org/about/cclicenses/
2. In case custom/internal licence/contract, create a unique URN on internal URL

Resolvability:
In case of IRI, the resource is not expected to be available within the same resource, will be dangling reference in most cases
In case it is URL, it does not need to resolvable

Serialization:
Shall be IRI. Meaning in case of RDF/XML it is in the xml object with tag rdf:resource and in case of JSONLD @id

from energy-reference-data.

Comment on using Compounds:

1. Help users to get access to most relevant information of a resource without resolving it
2. The main source is still available at the source ID
3. Compound may not be up to date
4. Compound may contain only some of the original resource attributes (usually only the ones that are most relevant to receiver)
