NPDI SCIM

• NPDI (Navy Product Data Initiative)
• To specify the requirements for and drive the
  implementation of product data systems based on
  an open architecture having suitable
  functionality and enterprise-wide
  interoperability to support affordable Navy ship
  design, construction and service life support
• Initial version of the IPDE Specification
  provided to the Navy represents the naval
  shipbuilders best efforts to build consensus
  among the various shipyards
• SCIM (Ship Common Information Model)
• Core data model for NPDI IPDE Specification
• Separate document from the IPDE Specification
  being produced by the NPDI Project, but is
  referenced by that IPDE Specification
• SCIM codifies the models developed and prototyped
  by the ISE Project under NSRP over the past nine
  years

Initial validation work from 2009 Panel Project

• Purpose
• To determine the feasibility of using existing
  AP214 translators with NPDI SCIM schema to
  improve the exchange of early and detail design
  data, and perform an initial validation of the
  SCIM
• Scope
• Develop linkage between AP 214 and SCIM file
• Ship and Moulded Form test cases
• Structural test cases
• Piping test cases
• Deliverables
• Test Cases
• SPS Paper technical approach
• Final Report includes SCIM recommendations

Panel ProjectLessons Learned

• Technical approach which links AP 214 geometry
  and SCIM ship design data is viable for CAD
  translators which generate XML attribute file
• SCIM schemas were sufficiently defined for NPDI
  specification, but additional work was required
  for translator usage
• SCIM model is missing STEP geometry definitions
• Determined use of SCIM still requires access to
  ISO STEP documentation
• STEP expertise required to implement SCIM schema
• STEP geometry viewer required to hand populate
  SCIM files

8
Panel ProjectRecommendations

• Incorporate external reference mechanism into
  SCIM
• Include documentation for STEP geometry model
  with the SCIM
• Define mandatory attributes in SCIM documentation
• Validate SCIM schema against STEP schema to
  identify any missing attributes or relationships
• Provide a SCIM Users Guide with examples
• Include fully expanded XML schemas with SCIM
  documents
• Reference required ISO STEP documentation where
  required
