PLM Data Model

PLM Data Model is the logical data object that defines the canonical entities of product data — Item, Revision, BOM, Document, Change, Workflow, User, Project — and the relationships between them. It is the schema on top of which every PLM workflow, integration, and report is built.

What it covers

  • Item / Revision / View as the foundational entities.
  • Structures and relationships (occurrences, has-document, has-change, alternate-of).
  • Lifecycle state machines governing transitions and approvals.
  • Effectivity — date, unit, serial, and configuration-rule effectivity.
  • Extensibility — custom subclasses, custom relationships, and metadata.
