`dct:title, dct:description, dct:rights, adms:versionNotes`: string or langString?

[VladimirAlexiev]

dct:description is defined to have range xsd:string.
I'm not sure where, I guess in one of the Header ontologies.

But it is often used as langString, et

urn:uuid:972cd4cd-25b0-4b70-96f9-eab4bfd32907 "This is the assessed element dataset for Espheim part of ReliCapGrid."@en

I don't think the original DCTERMS defines a range for it.
If you need a range, use rdf:PlainLiteral.

Same for dct:rights used as "Copyright"@en which is not xsd:string.

Hi Svein,

Can you see this?
perhaps not for immediate change in ReliCap, but a IOP topic as this will have the impact on the RDFS of the header and we need to come with with a group decision before changing in the ReliCap

[VladimirAlexiev]

DCT doesn't define any range for it, which allows using either string or langString:

dct:description
    dct:description "Description may include but is not limited to: an abstract, a table of contents, a graphical representation, or a free-text account of the resource."@en ;
    dct:hasVersion dchist:descriptionT-001 ;
    dct:issued "2008-01-14"^^xsd:date ;
    dct:modified "2008-01-14"^^xsd:date ;
    a rdf:Property ;
    rdfs:comment "An account of the resource."@en ;
    rdfs:isDefinedBy dct: ;
    rdfs:label "Description"@en ;
    rdfs:subPropertyOf dc:description .

So this problem falls under the wider "namespace hijacking"

• namespace hijacking; CGMES-NC Header-AP-Voc-RDFS2020 wrong terms Sveino/Inst4CIM-KG#8
• hijacked rdfs:domain in Header (MAJOR breakage) Sveino/Inst4CIM-KG#178

Meeting 2026-05-19:
Follow the example defined here for all the attribute: https://github.com/entsoe/relicapgrid/blob/cgmes-3.0_ncp-2.4_tc-1.1/docs/HeaderExample.xml
The constrains should be done in the SHACL and not in the RDFS. Long term goal it to reuse the DCAT ontology.
