SISO-REF-028-2011:  Distributed Debrief Control Protocol (DDCP) Study Group Final Report
The results of the 2008 DDCP Study Group survey reflected a positive reaction towards developing a DDCP standard.  The opinion was shared across a large cross section of distributed simulation practitioners including U.S. and international responses.  The original recommendation of the report was to stand up a Product Development Group (PDG) for the purposes of creating a distributed debrief interoperability standard.  Subsequent diminishing Study Group meeting attendance resulted in a delay.  Renewed interest in 2011 has resulted in the creation of the Distributed Debrief Control Architecture (DDCA) PDG. A multi-revision approach is recommended for developing the standard so that benefits can be quickly realized.  Ideally the initial standard would focus on the record and playback capabilities, which provide the backbone for the distributed debrief capability.  Additional standard revisions would roll out with enhancements organized through the PDG.  The experiences and lessons learned from other SISO product standardization groups would be leveraged in order to maximize benefit and minimize side effects caused by a multi-revision process.

SISO-REF-034-2010: Environmental Data Representation Standards (EDRS) PSG Annual Report
The Environmental Data Representation Standards PSG is required to support the SEDRIS family of
standards under the auspices of the SISO SAC. The PSG offers continuity and a place for developers and
users of the standards to:
- Establish and maintain a process to respond to questions concerning the language used in the standard,
the intention or result meant by a particular action, or an explanation of the reasons behind what the
standard says.
- Establish and maintain a Help Desk function using the SISO provided discussion board to answer
questions and provide support to the community.
- Establish and maintain a Problem/Change Request (PCR) process to collect problems and change
requests from the community. Conduct analysis and refinement of submitted problems and change
requests.
- When the PSG is operating in parallel with a PDG developing a revision to a product, forward refined PCRs
to the PDG for use in revision development.
-Maintain liaison with related Conference Forums, related PDGs, related PSGs, and related SGs.
- Identify, create, and maintain SISO reference products relating to the balloted products being supported.
- Identify and create Product Nominations for additional parts or supplements.
