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 ;
].
