merge and fix DatasetMetadata, Header, FileHeader

VladimirAlexiev commented 1 month ago

(started from https://github.com/Sveino/Inst4CIM-KG/issues/13, where I noticed dm used for two different purposes). There are 4 namespaces that are closely related: to my mind "model" is carrier of "header" or "metadata" and "differential model" is closely related to it:

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

Do you really need separate ontologies DatasetMetadata, Header (and there was FileHeader? Several of the ontology terms are defined in 2 of the 3. So I suggest to merge these files, and to reduce to 1-2 namespaces:

In addition:

eumd:DateTimeStamp is wrong
eumd:Model1, eumd:Model2 are junk prop names
These props don't follow the naming convention: md:Model.DependentOn, md:Model.Depending, md:Model.SupersededBy, md:Model.Supersedes

@Sveino agrees to merge them. Furthermore, he wants to replace as much as possible witg DCAT (so cim:Model will become dcat:Dataset).

Closely related to https://github.com/Sveino/Inst4CIM-KG/issues/8
@Sveino sent METADATA FOR DATASET AND DISTRIBUTION SPECIFICATION 2024-09-10 VERSION 2.4.0 FOR CIM WG REVIEW (to go into https://github.com/Sveino/Spec4CIM-KG)
and he noted "describes the requirements for the DCAT-AP-CIM. It explains that two additional attributes that we have extended DCAT-AP with. We should not hijack any namespace dcat-cim shall only refer to the extension"
I like this a lot: DCAT-AP-CIM would follow the tradition of DCAT-AP (EU dataset), DCAT-AP-Stat (statistical), DCAT-AP-Geo (Geographical) etc. It should only describe the use of DCAT terms, but not redefine them.
IMHO no new namespace is needed: there is already md (and eumd that has only 1 term!)
