Description

Hi - I've been trying to get the Kiwi reasoner to work with rules where the body section contains a string literal. It was suggested that I raise a jira ticket to report this as a possible bug.

For example:

($s $p "Hello") -> ($s $p "There")

The literal "Hello" will match any triple that has an object that is set to "Hello"@en but not if the triple has an un-tagged literal value of just "Hello".

When it infers/produces triples with a string literal as the object it will add the language decoration too, so the above would infer "There"@en.

How can I turn off the language attribute please?
How can I match other types of literal objects; e.g., numbers or other ^^XML types?

Many thanks

Alan
