Hi New York Semantic Web community,

The session with Chris Welty from IBM on September 17 is already fully
booked and we still have 10 days to go. In case you are not already on
the RSVP 'Yes' list please indicate your interest to attend the RIF
session by joining the waiting list. Also if you can provide a larger
meeting space please get in touch with me directly. We will consider
free and fee based locations for this event.

I understand the importance of rules to help us introduce Semantic Web
technologies in high volume transaction environments where most
tableaux reasoners will most likely fail. To help you decide whether
or not this session is for you I have tagged the event with
"Session-Level: Intermediate-Advanced". I emphasize the advanced part
of the label here.

Michael Kifer, State University of New York at Stony Brook, did a good
job in describing the efforts of the Rule Interchange Format (RIF)
Working Group as follows:

"The Rule Interchange Format (RIF) is an activity within the World
Wide Web Consortium aimed at developing a Web standard for exchanging
rules. The need for rule-based information processing on the Semantic
Web has been felt ever since RDF was introduced in the late 90’s. As
ontology development picked up pace this decade and as the limitations
of OWL became apparent, rules were firmly put back on the agenda. RIF
is therefore a major opportunity for the introduction of rule based
technologies into the main stream of knowledge representation and
information processing on the Web.

Despite its humble name, RIF is not just a format and is not primarily
about syntax. It is an extensible framework for rule-based languages,
called RIF dialects, which includes precise and formal specification
of the syntax, semantics, and XML serialization. In this paper we will
discuss the main principles behind RIF, introduce the RIF
extensibility framework, and outline the Basic Logic Dialect—the only
fully developed RIF dialect so far."
