Background
2.1

• ITUs Constitution/Convention asks that ITU-T
  cooperate with other world and regional
  intergovernmental organizations, and those
  non-governmental organizations concerned with
  telecommunications".
• ITU-T has a wealth of instruments in place to
  collaborate with others

10
ITU-T Rec. A.4 Communication process between
ITU-T and Forums and Consortia
2.2

• Goal to facilitate documentation exchange
• Criteria pretty straightforward and common sense
• Evident ones subject area should be of relevance
  to the work done in ITU-T
• Documents submitted to ITU-T should not contain
  proprietary information (no restriction for
  distribution)
• Forum membership should not preclude ITU MS or SM
• Patent policy must be consistent with ITU-T
  patent policy
• A formal communication process can initiated
  either by the forum or by ITU-T (e.g., Study
  Group or Director of TSB)
• Can be initiated at any time

11
ITU-T Rec. A.5 Generic procedures for including
references to documents of other organizations in
ITU-T Recommendations
2.3

• Rules for referencing standards from other
  qualified organizations (with the exception of
  ISO and IEC)
• Apply to those standards used as normative
  references (integral part of the Recommendations)
• The normative references from qualified
  organizations need to be justified (status of
  approval, rational for the referencing, degree of
  stability, IPR isues,)
• Instead of referencing, it may be decided (by the
  SG) to incorporate the text of another
  organization into the text of a Recommendation
  (in part or in full) with th e permission of the
  organization

12
ITU-T Rec. A.6 Cooperation and exchange of
information between ITU-T and national and
regional standards development organizations
2.4

• Similar in spirit to A.4
• Global Standards Collaboration (GSC) exchange
  information between participating standards
  organizations to facilitate collaboration and
  enhance the process of global telecommunication
  standardization in the ITU
• Annual meetings of 9 leading national and
  regional standards organizations and ITU (ACIF,
  ARIB, ATIS, CCSA, ETSI, ISACC, TIA, TTA, TTC,
  ITU)(15 Observers at GSC-11 ANSI, CEPT, CITEL,
  GSMA, IEEE, IETF, OMA, SCTE,)

13
ITU-T Rec. A.7 Focus Groups Working methods and
procedures
2.5

• Focus Groups are an instrument providing an
  additional working environment for the quick
  development of standards in specific areas
• Focus Groups have freedom to organize and finance
  themselves. Focus Groups can be created very
  quickly, are usually short-lived and can choose
  their own working methods, leadership, financing,
  and types of deliverables
• Focus Groups report to a parent Study Group
• The Focus Group deliverables may be further
  progressed as ITU-T Recommendations
• The establishment of a Focus Group can be
  considered to start work in new areas with joint
  membership (ITU-T / SDO) participation in the
  development of specifications
• The establishment of a Focus Group is an option
  considered for resolving any technical divergence
  between ITU-T and OASIS when updating X.1141
  (SAML 2.0) and XACML (2.0)

Summary on issues
3.4

• OASIS is qualified under ITU-T A.4 A.5
• ITU-T SG 17 agreed to convert SAML and XACML
  instead of a simple referencing
• Editing necessary (multipart standard / 1-Part
  Rec., normative/informative references)
• IPR
• Ongoing maintenance
• PR

19
Ongoing maintenance
3.5

• Maintain the communication channel with OASIS
• OASIS plans further revisions of SAML and XACML
  that will be resubmitted to ITU-T
• Sharing of defect reports and proposals for
  improvements
• Appointment of liaison officers
• Relevant OASIS TCs will continue to collect and
  respond to change proposals
• In case of substantial different conclusions
  about some technical issues, a Focus Group may be
  established for harmonization and resolution of
  divergent conclusions

20
Conclusion
4.

• Well established collaboration between ITU-T and
  OASIS
• MoU on E-business (with ISO, IEC and UN/ECE)
• Joint Workshop on Public Warning, Geneva, 19-20
  October 2006 (started during WSIS, Phase II,
  Tunis, November 2005)
• OASIS standards accepted as ITU-T
  Recommendations(13 June 2006) X.1141 (SAML 2.0)
  and X.1142 (XACML 2.0)
• Future cooperation areas
• OASIS Common Alerting Protocol (CAP) standard to
  be progressed as an ITU-T Recommendation
• Accepted as work item at Rapporteur Meeting in
  September 2006
• Expect formal work item adoption in December 2006
  ? X.CAP, consent foreseen by September 2007
• Web Services Security SOAP Message Security (WSS
  v1.1)
• Other cooperation mechanisms could be explored
  workshops, Focus Groups, etc
