I don't know what is going on anymore =(
First, It is important to note that I am reading the rule content from a
file that I already tested using "ja:rulesFrom", thus I believe the
syntax inside is ok. I mean, there are no problems like you mentioned about
the columns (it was a copy and paste problem).
Now I am using """ to enclose the rules. So my code is as follows:
:model_inf a ja:InfModel ;
ja:baseModel :tdbGraph ;
ja:reasoner [
ja:reasonerURL <${reasonerURL}> ;
ja:rule """
${rules}
""" ;
]
.
And ${rules} has the file content (that has more than one rules):
#-*-mode: conf-unix-*-
@prefix time: <http://www.w3.org/2006/time#>
@include <owlmicro>
-> table(owl:sameAs).
#---------------------------------------------------------------------------
# Equality
#---------------------------------------------------------------------------
sameAs_symmetry:
(?x owl:sameAs ?y)
-> (?y owl:sameAs ?x).
sameAs_transitivity:
(?x owl:sameAs ?y)
(?y owl:sameAs ?z)
-> (?x owl:sameAs ?x).
sameAs_Thing1:
-> [(?x rdf:type owl:Thing) <- (?x owl:sameAs ?y)].
sameAs_Thing2:
-> [(?x owl:sameAs ?x) <- (?x rdf:type owl:Thing)].
The error persists expecting '(':
06:23:01 WARN Admin :: [4] RC = 500 : caught: Expected '(' at
start of clause, found @prefix
At '#-*-mode: conf-unix-*- @prefix '
org.apache.jena.assembler.exceptions.AssemblerException: caught: Expected
