Abbreviated as RIF, the
Rule Interchange Format is a
W3C recommended effort to develop a format for interchange of rules in
rule-based systems on the
Semantic Web. The
overall RIF design takes the form of a layered
architecture organized around the notion of a dialect. RIF has a number of
extensions to support features such as objects and frames,
URIs as identifiers for concepts, and
XML
schema data types. While this makes RIF a
Web language, RIF is designed to enable
interoperability among rule languages in general, and is not limited to the Web.
