Ok, clear
I note that it doesn’t help here when the better subClassOf iso
equivalentClass is used.
Wrt to the simple restriction: it does not seem to convert either in
5.3.2. So I’ll wait for the release of 5.4 for that.
Below you see the result after conversion (this time without deleting
the original owl/rdfs restrictions):
:BigSpace
rdf:type owl:Class ;
rdf:type sh:NodeShape ;
rdfs:subClassOf :Space ;
rdfs:subClassOf [
rdf:type owl:Restriction ;
owl:allValuesFrom :BigPump ;
owl:onProperty :hasPump ;
] ;
owl:disjointWith :SmallSpace ;
owl:equivalentClass [
rdf:type owl:Restriction ;
owl:allValuesFrom [
rdf:type rdfs:Datatype ;
owl:onDatatype xsd:float ;
owl:withRestrictions (
[
xsd:minExclusive "150.0"^^xsd:float ;
]
) ;
] ;
owl:onProperty :area ;
] ;
.
As you can see only
rdf:type sh:NodeShape ;
has been added.

Michel,
I have not tried the OWL to SHACL converter in 5.3, only in the
5.4 which is not yet generally available.
The converter is “work in progress” and I know that it was
extended for 5.4. However, it will not convert all possible
combinations of OWL axioms. Only the most common ones. To decide
what constitute a common pattern, we looked at several well known
ontologies such as FIBO and picked patterns that cover 80-90% of
the modeling axioms.
Based on my 5.4 experience:
rdfs:subClassOf [
rdf:type owl:Restriction ;
owl:allValuesFrom :BigPump ;
owl:onProperty :hasPump ;
] ;
Should be converted
You should see something like
:BigSpace
sh:property [
sh:path :hasPump ;
sh:class :BigPump ;
]
owl:equivalentClass [
rdf:type owl:Restriction ;
owl:allValuesFrom [
rdf:type rdfs:Datatype ;
owl:onDatatype xsd:float ;
owl:withRestrictions (
[
xsd:minExclusive "150.0"^^xsd:float ;
]
) ;
] ;
owl:onProperty :area ;
] ;
Will not be converted. It is not one of the patterns we currently
support in the conversion.
Yes, this is because owl:equivalentClass axioms really do carry
different meaning, and we don't want to pretend that they can be
converted automatically. Some manual post-processing will be needed
in these cases, e.g. converting them to SHACL-AF rules.

Hi Irene,
When converting the owl restrictions to SHACL within tbc, the
2 restrictions from:
:BigSpace
rdf:type owl:Class ;
rdfs:subClassOf :Space ;
rdfs:subClassOf [
rdf:type owl:Restriction ;
owl:allValuesFrom :BigPump ;
owl:onProperty :hasPump ;
] ;
owl:disjointWith :SmallSpace ;
owl:equivalentClass [
rdf:type owl:Restriction ;
owl:allValuesFrom [
rdf:type rdfs:Datatype ;
owl:onDatatype xsd:float ;
owl:withRestrictions (
[
xsd:minExclusive "150.0"^^xsd:float ;
]
) ;
] ;
owl:onProperty :area ;
] ;
.
Seem not converted.
Was this to be expected?
What IS generated, I do not understand:
[
rdf:type rdfs:Datatype ;
owl:onDatatype :area ;
].
[
rdf:type rdfs:Datatype ;
owl:onDatatype :area ;
].
[
sh:class :BigPump ;
].
[
sh:class :SmallPump ;
].
