Key Points

• XML is gaining acceptance as a data interchange
  format for simulation data
• SBA is a multi-faceted problem. To address it,
  we need a structure to breakout its components
  and identify the enablers needed.
• Data exchange is a key problem that SBA must
  address.
• Multiple SAFs exist, each with their own
  capabilities. Using key features of one in
  another has become a common practice.

XML is gaining acceptance as a data interchange
format for simulation data

• Explanation XML is a set of rules, guidelines,
  and conventions for designing text formats for
  data. It produces data files that are easy for
  computers to read.
• Recommendation VWS will continue to monitor
  successful uses of XML. XML could become a
  standard format for interchange of certain types
  of simulation data (behaviors, equipment and
  performance characteristics, etc.).

SBA is a multi-faceted problem

• Explanation SBA encompasses many key elements.
  To address it, it must be decomposed and the
  focus must be put on the key enablers.
• Recommendation VWS will continue to support the
  SBA movement. We would like to consider a joint
  study group with SAPD to investigate further what
  areas of SBA SISO can help with. We will
  continue this study group discussion on the VWS
  (SAPD) reflector(s).

Data exchange is a key problem that SBA must
address

• Explanation MS is used today to support system
  acquisition. However, many different types of
  tools are used, and there are no standard formats
  or data interchange mechanisms for them (i.e.
  CAD, mission simulation, virtual simulator). XML
  is one candidate to facilitate data transport
  between tools.
• Recommendation VWS will continue to look for
  SBA concepts in future Call for Papers. Data
  exchange may be one possible topic for a SISO
  study group on SBA.

Multiple SAFs exist, each with their own
capabilities.

• Explanation There are many SAF simulations
  available today (ModSAF, OneSAF Testbed,
  JointSAF, etc.). Each of these simulations has
  their own capabilities. Some SAF users routinely
  mix good features of different SAFs to meet their
  needs.
• Recommendation SISO should continue to invite
  papers on SAF simulations to provide data on
  capabilities and uses of current SAFs. The
  emerging OneSAF Objective System should provide
  an integrating framework for the best features of
  current SAFs.
