I don't know your full query restrictions, but without given properties
it would be a "simple" property path, no? Something like
owl:someValuesFrom/((owl:intersectionOf|owl:unionOf)/list:member)?
where the list closure is optional and if you want to make it nestested
(owl:someValuesFrom/((owl:intersectionOf|owl:unionOf)/list:member)?)*
So a query like
prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>
prefix owl: <http://www.w3.org/2002/07/owl#>
prefix list: <http://jena.apache.org/ARQ/list#>
select * {
?subclass rdfs:subClassOf|owl:equivalentClass
[(owl:intersectionOf|owl:unionOf)/list:member/(owl:someValuesFrom/((owl:intersectionOf|owl:unionOf)/list:member)?)*
?m]
FILTER(isIRI(?m))
}
could work. You could even try to make it more generic.
But maybe you have different requirements, in that case it would be
easier to help with sample data. My sample data now was
@prefix :
<http://www.semanticweb.org/user/ontologies/2022/11/untitled-ontology-100#>
.
@prefix owl: <http://www.w3.org/2002/07/owl#> .

Is there a shortcut for making queries where a data value can be
single item or list of items?
For example this is how I do a query now using UNION. Both parts are
identical except for the single/list section in owl:someValuesFrom [].
This is still somewhat readable but if there are multiple occurences,
query lenght and complexity grows exponentially.

The data is not ours so we can't make everything lists.
