Hello Andy, I manually escaped \n and " characters and some errors were corrected, thanks. However, consider that I want to use the following string rules ( string_rules_variable):
#-*-mode: conf-unix-*- @prefix time: <http://www.w3.org/2006/time#> @include <owlmicro> -> table(owl:sameAs). #----------------------------- sameAs_symmetry: (?x owl:sameAs ?y) -> (?y owl:sameAs ?x). And as I said before this is how I am using in fuseki: > :model_inf a ja:InfModel ; > ja:baseModel :tdbGraph ; > ja:reasoner [ > ja:reasonerURL <http://jena.hpl.hp.com/2003/GenericRuleReasoner> ; > ja:rule "[string_rules_variable]"`; But Fuseki is not recognizing prefix: org.apache.jena.assembler.exceptions.AssemblerException: caught: Expected '(' at start of clause, found @prefix Do you have any thoughts on how to solve this? Thanks in advance!
