Naming convention: Policy / Policy Item?

[zyzzyxdonta]

Since documents that describe all the rules are usually called "policy", I think we should make the distinction between "policy" and "policy item". A policy would be comprised of one or more policy items. E.g.:

• Policy: HZDR Software Policy
• Policy Item: Only Apache 2.0 license may be used

This means a policy would likely be a file like this (i.e. an owl:Ontology, because that's how the import mechanism works in SHACL):

@prefix owl: <http://www.w3.org/2002/07/owl#> .

<> a owl:Ontology .
<> owl:imports <../policy-items/license.ttl> .

Whereas a policy item would look like this (one or more SHACL things such as shapes, constraint components, ...):

@prefix codemeta: <https://doi.org/10.5063/schema/codemeta-2.0#> .
@prefix scex: <https://schema.software-metadata.pub/software-card/2025-01-01/examples/#> .
@prefix schema: <https://schema.org/> .
@prefix sh: <http://www.w3.org/ns/shacl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

scex:licenseRequirements a sh:NodeShape ;
    sh:targetClass schema:SoftwareSourceCode ;

    sh:property [
        sh:name "Apache-2.0 license" ;
        sh:description "Apache-2.0 license must be used" ;

        sh:path schema:license ;
        sh:datatype xsd:string ;
        sh:hasValue "https://spdx.org/licenses/Apache-2.0" ;
    ] ;
