Dear Advisory Committee representative,

This is a W3C Patent Policy Call for Exclusions for the following
Recommendation Track documents:

- RIF Basic Logic Dialect
  exclusion opportunity ending on 28 March 2008
- RIF RDF and OWL Compatibility
  exclusion opportunity ending on 28 March 2008

These specifications were produced by the Rule Interchange Format
Working Group.

If you do not wish to exclude patent claims during this exclusion
opportunity, no further action is required.

Participants made a Royalty-Free licensing commitment upon joining this
Working Group. With the publication of this document, per section 4.1 of
the Patent Policy [1] Participants have an opportunity until 28 March
2008 to exclude patent claims reading on this Recommendation track
document. Excluded claims are not subject to the licensing requirements
of the W3C Patent Policy for this document. For more information about
exclusions, please see

To make exclusions, please use the following form:

The Patent Policy anticipates that the documents will evolve during the
90 days following the first publication.  Per section 4.1 of the Patent
Policy [1], whatever draft is available on 28 January 2008 establishes
the reference material [3] for the purposes of this exclusion
opportunity. Just after 28 January 2008, we will send a reminder and
identify the reference draft. Due to the anticipated instability of the
documents prior to 28 January 2008, Participants may wish to exclude any
claims only after publication of the reference draft (and no later than
the end of the exclusion opportunity).

Per section 4.2 of the Patent Policy [2], a Participant may resign from
the Working Group before 28 January 2008 and be excused from all
licensing commitments arising out of Working Group participation.

To resign from the Working Group before 28 January 2008, please use the
following form:

Summary information for this group related to the W3C Patent Policy is
