Mis-defined Prefixes

[VladimirAlexiev]

There are a couple of problems with prefixes:

• dcterms is wrong (has exraneous hash), as you can see at https://prefix.cc/dcterms:

  @prefix dct      : <http://purl.org/dc/terms/> .
  @prefix dcterms  : <http://purl.org/dc/terms/#> .

• For consistency, only dct should be used (which is the more popular spelling), not dcterms

This below is an expected issue, and will cause confusion if all ontologies are used together:

• The CIM and CGMES "business" prefixes are defined twice. This comes from the RDFSEd2Beta style (used for CGMES) vs RDFS2020 style (used for CGMES NC)

  @prefix cim      : <http://iec.ch/TC57/CIM100#> .
  @prefix cim      : <https://cim.ucaiug.io/ns#> .
  @prefix eu       : <http://iec.ch/TC57/CIM100-European#> .
  @prefix eu       : <https://cim.ucaiug.io/ns/eu#> .

• dm is used for two different purposes. And there's also eumd: https://github.com/Sveino/Inst4CIM-KG/issues/69

  dm: <http://iec.ch/TC57/61970-552/DifferenceModel/1#> .
  dm: <https://ap-voc.cim4.eu/DatasetMetadata#> .
  eumd: <https://cim4.eu/ns/Metadata-European#> .

Maybe you wanted to say dct instead of dcterms. We found some references where it was recommended to use dcterms instead of dct

DCAT 3 - recently W3C Recommendation refers it as dcterms https://www.w3.org/TR/vocab-dcat-3/#normative-namespaces

We only had to put # at the end for all namespaces because we have tooling issue. Once we have the spec and align the tooling we will need to use / and # as it comes from the original namespace

I understood that there is a tendency to abandon # but I see in the DCAT they kept it. I guess what we want to achieve here is to be able to do our RDFS using original namespaces by W3C and fix tooling

• yes, I mean dcterms not dcat
• if DCAT uses dcterms then ok, use that, and don't use dct (it's important to be consistent)
• You absolutely must use correct external namespaces: cannot add #
• Hash vs slash: using # for ontology terms is ok. For large collections of things you should use /
