Hi!
as long as I haven't mixed something up wrt. the proposed feature of
sh:NodeConstraints + under the assumption that sh:valueshape can be used
in sh:nodeconstraints too, following shapes expressed in SHACL should be
equivalent to your ShEx shapes ->
ex:PersonShape
a sh:Shape ;
sh:constraint [
a sh:NodeConstraint ;
sh:valueShape [
sh:constraint [
a sh:OrConstraint ;
sh:shapes (
[
sh:property [
sh:predicate ex:name ;
sh:datatype xsd:string ;
]
]
[
sh:property [
sh:predicate ex:firstname ;
sh:minCount 1 ;
sh:datatype xsd:string ;
] ;
sh:property [
sh:predicate ex:lastname ;
sh:datatype xsd:string ;
]
]
)
]
] ;
sh:maxCount 1 ;
] ;
.
ex:ClosedIssueShape
a sh:Shape ;
sh:constraint [
a sh:NodeConstraint ;
sh:valueShape [
sh:constraint [
a sh:OrConstraint ;
sh:shapes (
[
sh:property [
sh:predicate ex:resolution ;
sh:valueShape ex:RejectionShape ;
]
]
sh:property [
sh:predicate ex:rejection ;
sh:valueShape ex:RejectionShape ;
]
]
)
]
] ;
sh:minCount 1 ;
] ;
.

> When combining Shapes with and and or operators, it is natural to
> group those shapes. In compact syntax, grouping is represented by
> parenthesis.
>
> For example:
>
> <PersonShape> {
> foaf:name xsd:string
> | ( foaf:firstName xsd:string +
> , foaf:lastName xsd:String
> )
> }
>
> A natural extension is to add cardinalities on those groups. SHACL
> spec should define if groupings and cardinalities over groupings are
> possible.
