Call for Exclusions: SKOS Simple Knowledge Organization System Reference

Dear Advisory Committee representative,

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

- SKOS Simple Knowledge Organization System Reference
  (http://www.w3.org/TR/skos-reference),
  exclusion opportunity ending on 23 June 2008 23:59 UTC

This specification was produced by the Semantic Web Deployment 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 23 June
2008 23:59 UTC 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
http://www.w3.org/Consortium/Patent-Policy-20040205/#sec-Exclusion

To make exclusions, please use the following form:
 http://www.w3.org/2004/01/pp-impl/39408/exclude

The Patent Policy anticipates that the document will evolve during the
90 days following the first publication.  Per section 4.1 of the Patent
Policy [1], whatever draft is available on 24 April 2008 establishes the
reference material [3] for the purposes of this exclusion opportunity.
Just after 24 April 2008, we will send a reminder and identify the
reference draft. Due to the anticipated instability of the document
prior to 24 April 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 24 April 2008 and be excused from all licensing
commitments arising out of Working Group participation.

To resign from the Working Group before 24 April 2008, please use the
following form:
