In order to interchange rules between different rule languages and platforms, Working Group I1 has developed a rule interchange format R2ML. This format can be used to make translations from/to F-Logic, RuleML, Jess, Jena2 and partially JBoss Rules. The demo shows a service, which implements transformations and allows different clients to connect and interchange rules from/to R2ML. The current demo shows a web-client, implemented in PHP, for translation from the F-Logic XML to Jena via R2ML. The transformation consists of two steps: from F-Logic XML to R2ML and then from R2ML to Jess.
