Hi all,
I am trying the SHACL rule example from
https://www.w3.org/TR/shacl-af/#rules-examples
with the SHACL API from
https://github.com/TopQuadrant/shacl
Version 1.3.2.
With the attached file, I get the following error message:
"Exception in thread "main" org.apache.jena.query.QueryParseException:
Line 3, column 39: Unresolved prefixed name: ex:area"
Is this a bug in the SPARQL implementation, or is the example from the
spec wrong?
The example as printed in the spec is incomplete, because it does not
sh:declare the prefix.
To make it complete, either
add
ex:
sh:declare [
sh:prefix "ex" ;
sh:namespace "http://example.com/ns#"^^xsd:anyURI ;
] .
or put the prefix into the beginning of the query string and delete the
sh:prefixes link:
sh:construct """
PREFIX ex: "http://example.com/ns#";
CONSTRUCT ...
See https://www.w3.org/TR/shacl/#sparql-prefixes for the general topic.
Unrelated to this specific feature: I tried to install the latest
version of the SHACL API and then get an error
"org/topbraid/shacl/tools/Infer has been compiled by a more recent
version of the Java Runtime (class file version 55.0), this version of
the Java Runtime only recognizes class file versions up to 52.0"
I am using on mac os x the latest JRE from Oracle
Java(TM) SE Runtime Environment (build 1.8.0_311-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.311-b11, mixed mode)
Is there a way to work with the latest SHACL API, maybe by working
with a different JRE?
Yes, you need to upgrade your Java version because the Jena API that we
use requires Java 11.
