This page belongs to the PDM Usage Guide.

The STEP PDM Schema is a core set of entities in STEP that support the mapping of concepts for Product Data Management (PDM). This document and the PDM Schema are the result of a cooperative development process between ProSTEP and PDES, Inc. The PDM Schema has been established to promote interoperability between STEP APs in the area of product data management.

This document introduces a set of functional areas that together describe the scope of functionality of the 1.2 release of the PDM Schema. These units of functionality suggest a modular structure for the PDM Schema.

Units of Functionality

The product data management requirements addressed by the PDM Schema are organized into groupings of related concepts. These groups provide a logical grouping of AIM entities for the purpose of a clear structure within the PDM Schema. These groups suggest a modular structure for the PDM Schema in line with the current direction towards modularization of the technical contents of STEP integrated resources and Application Protocols.

The modular semantic units of functionality are listed below:

  • Part Identification,
  • Part Classification,
  • Part Properties,
  • Part Structure and Relationships,
  • Document Identification,
  • Document Classification,
  • External Files,
  • Relationships Between Documents and Constituent Files
  • Document and File Properties,
  • Document and File Association to Product Data,
  • Document and File Relationships,
  • Alias Identification,
  • Authorization,
  • Configuration and Effectivity Information,
  • Work Management Data.
