Eliminate the redefinition of properties of common vocabularies

[cristianvasquez]

Some values of properties from external vocabularies are being rewritten, and need to be removed.

Examples of such properties are: rdfs:range or rdfs:domain

This can pose difficulties in the case of using the vocabularies together as one graph

I'm linking a list of triples that were redefined in this gist, it might serve as a reference for this task. Also the original values

The list was extracted from a set of vocabularies in a triplestore using this query:

SELECT distinct ?graph ?s ?p ?o
WHERE {
  graph ?graph {
    ?s a ?type .
    ?s ?p ?o .
    FILTER (isIRI(?o)) .
  }
}

The list of vocabularies taken into account:

There was a discussion about how to reuse the external vocabularies. While I believe that lexical adaptations should be discouraged, I have discovered that this is a practice in the semantic standardisation community, including the ePO working group.

How the lexical adaptations can be implemented is described in the SEMIC style guide: for classes, for properties.

Hi, thank you for noticing.

Lexical adaptations are useful indeed. I've relaxed the list of elements to remove, and I'll update the issue description

[cristianvasquez]

One option to implement this is a CONSTRUCT over the dataset that filters out things with Subject from known vocabularies.

This can be applied as post-processing
