SHACL: Require sh:property to be a URI - sparql

Question

I was wondering if there's a way to specify that a given sh:property is expected to have a value of a URI without any particular class.
In the example SHACL below, the property meta:value would only allow URIs, although I don't know of a way to represent it in SHACL.
Example SHACL
#prefix sh: <http://www.w3.org/ns/shacl#> .
#prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
#prefix meta: <metadata#> .
#prefix meta_sh: <metadata/shacl#> .
meta_sh:Entry
a sh:NodeShape;
sh:targetClass meta:Entry;
sh:property [
sh:path meta:value;
# Value expected to be a URI
sh:minCount 1; # Required; 1 or more
];
sh:property [
sh:path meta:time;
sh:datatype xsd:dateTime;
sh:minCount 1; sh:maxCount 1; # Required; 1
];
.
Example Data
#prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
#prefix meta: <metadata#> .
#prefix data: <data#> .
data:Entry_001
a meta:Entry;
meta:value data:ProductListing_459; # URI
meta:value data:RentalListing_934; # URI
meta:time "2022-06-15T06:20:31Z"^^xsd:dateTime;
.

Answer 1

this should work:
#prefix sh: <http://www.w3.org/ns/shacl#> .
#prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
#prefix meta: <metadata#> .
#prefix meta_sh: <metadata/shacl#> .
meta_sh:Entry
a sh:NodeShape;
sh:targetClass meta:Entry;
sh:nodeKind sh:IRI ;
sh:property [
sh:path meta:value;
# Value expected to be a URI
sh:minCount 1; # Required; 1 or more
];
sh:property [
sh:path meta:time;
sh:datatype xsd:dateTime;
sh:minCount 1; sh:maxCount 1; # Required; 1
];
.

Answer 2

Yes, you are right, the sh:nodeKind has to be part of the property shape.
The reason why it still not worked: the way you defined the prefixes. They were no full URIs so the SHACL processor added some parts (maybe the disk location of the file, depends). The result: the meta in the shapes never matched the meta in the data.
This works:
SHACL
#prefix sh: <http://www.w3.org/ns/shacl#> .
#prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
#prefix meta: <https://example.org/#> .
#prefix meta_sh: <metadata/shacl#> .
meta_sh:Entry
a sh:NodeShape;
sh:targetClass meta:Entry;
sh:property [
sh:path meta:value;
sh:nodeKind sh:IRI ;
sh:minCount 1; # Required; 1 or more
];
.
Data
#prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
#prefix meta: <https://example.org/#> .
#prefix data: <data#> .
data:Entry_001
a meta:Entry;
meta:value data:RentalListing_934 ; # URI
meta:time "2022-06-15T06:20:31Z"^^xsd:dateTime;
.
data:Entry_002
a meta:Entry;
meta:value "this is not an uri" ; # No Uri
meta:time "2022-06-15T06:20:31Z"^^xsd:dateTime;
