| Title: | A Conceptual Data Model of Datum Systems |
| Published: | September 23, 1999 |
| Abstract: | A new conceptual data model that addresses the geometric dimensioning and tolerancing concepts of datum systems, datums, datum features, datum targets, and the relationship among these concepts, is presented. Additionally, a portion of a related data model, Part 47 of STEP (ISO 10303-47), is reviewed and a comparison is made between it and the new conceptual data model. |
