2. OGF IPR Policies Apply
• “I acknowledge that participation in this meeting is subject to the OGF Intellectual Property Policy.”
• Intellectual Property Notices Note Well: All statements related to the activities of the OGF and addressed
to the OGF are subject to all provisions of Appendix B of GFD-C.1, which grants to the OGF and its
participants certain licenses and rights in such statements. Such statements include verbal statements in OGF
meetings, as well as written and electronic communications made at any time or place, which are addressed to:
• the OGF plenary session,
• any OGF working group or portion thereof,
• the OGF Board of Directors, the GFSG, or any member thereof on behalf of the OGF,
• the ADCOM, or any member thereof on behalf of the ADCOM,
• any OGF mailing list, including any group list, or any other list functioning under OGF auspices,
• the OGF Editor or the document authoring and review process
• Statements made outside of a OGF meeting, mailing list or other function, that are clearly not intended to be
input to an OGF activity, group or function, are not subject to these provisions.
• Excerpt from Appendix B of GFD-C.1: ”Where the OGF knows of rights, or claimed rights, the OGF secretariat
shall attempt to obtain from the claimant of such rights, a written assurance that upon approval by the GFSG
of the relevant OGF document(s), any party will be able to obtain the right to implement, use and distribute
the technology or works when implementing, using or distributing technology based upon the specific
specification(s) under openly specified, reasonable, non-discriminatory terms. The working group or research
group proposing the use of the technology with respect to which the proprietary rights are claimed may assist
the OGF secretariat in this effort. The results of this procedure shall not affect advancement of document,
except that the GFSG may defer approval where a delay may facilitate the obtaining of such assurances. The
results will, however, be recorded by the OGF Secretariat, and made available. The GFSG may also direct that
a summary of the results be included in any GFD published containing the specification.”
• OGF Intellectual Property Policies are adapted from the IETF Intellectual Property Policies that support the
Internet Standards Process.

12. Press, Blogs, Twitter
The Open Cloud Computing Interface (OCCI) is an
example of an attempt to deal with a large part of
this challenge (Interop). However, differentiation
will still be possible through extensions, quality
of features and--yes--some custom interfaces...
(news.cnet.com)
[…] OCCI email thread is also interesting from a human
and organizational perspective (stage.vambenepe.com)
Cloud Central's implementation of this open
interface would in fact make it "a
differentiator to other clouds at the
market (itnews.com.au)
[…] team will evaluate and consider
existing similar mechanisms including OVF,
the OCCI, and the Libvirt XML Format.
