WG3/WG12 Saturday Modules Meeting 3 Levels of
Modules

• Level 0 Foundation Modules
• WG12 owner
• Level 0 will define entities, types, extensible
  selects,
• Global Rules allowed under special circumstances
• Level 1 Unit of Functionality Module
• WG3, JWG8 or JWG9 owner
• A module or an aggregation of a set of modules
  (Level 0 or 1) to provide a common set of
  functionality that will be reused in other
  modules.
• Level 1 (UoF) module will define entities, types,
  selects, etc. and may extend selects but will
  typically not define global rules

13
WG3/WG12 Saturday Modules Meeting - 3 Levels of
Modules

• Level 2 Implementation Modules (formally
  Conformance Class)
• WG3, JWG8, or JWG9 Owner
• A collection of modules (Level 0, 1 or 2) that
  define a capability that can be implemented and
  against which conformance classes may be defined
• Requires a long form (ARM and MIM) generated from
  short forms of child modules
• Level 2 modules will define entities, types,
  selects, etc., may extend selects in other
  modules, and will define subtype constraints,
  global rules, and complete selects (no empty
  selects allowed)
• Each AP shall have a Level 2 module which
  provides a root to its complete scope. This is
  known as the AP module
• Recommended practice that no new entities are
  created for Level 2 modules
