CPM2 is a generic, abstract model with generic semantics. CPM2 gives equal status to three aspects of a product or artifact: its function, its form, and its behavior. Thus, CPM2 can support functional reasoning about a product in the conceptual stages of design, the recording and the modeling of its behavior in the postdesign stages as well as the \u201ctraditional\u201d design phases. Three levels of CPM2 models, de-noted as the conceptual, intermediate, and implementation models, are described. Extensions of the initial CPM are briefly pre-sented. The facilities in CPM2 for building experimental intermediate systems are demonstrated and a short illustrative example is given. The full practical evaluation of CPM2 will require the development and use of implementation models.<\/jats:p>","DOI":"10.1115\/1.2830842","type":"journal-article","created":{"date-parts":[[2008,3,3]],"date-time":"2008-03-03T14:38:32Z","timestamp":1204555112000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":95,"title":["CPM2: A Core Model for Product Data"],"prefix":"10.1115","volume":"8","author":[{"given":"Steven J.","family":"Fenves","sequence":"first","affiliation":[{"name":"Carnegie Mellon University, Pittsburgh, PA 15213;  Manufacturing Systems Integration Division, National Institute of Standards and Technology, Gaithersburg, MD 20899-8263"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebti","family":"Foufou","sequence":"additional","affiliation":[{"name":"LE2i Laboratory, University of Burgundy, B.P. 47870, 21078 Dijon, France;  Manufacturing Systems Integration Division, National Institute of Standards and Technology, Gaithersburg, MD 20899-8263"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Conrad","family":"Bock","sequence":"additional","affiliation":[{"name":"Manufacturing Systems Integration Division, National Institute of Standards and Technology, Gaithersburg, MD 20899-8263"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ram D.","family":"Sriram","sequence":"additional","affiliation":[{"name":"Manufacturing Systems Integration Division, National Institute of Standards and Technology, Gaithersburg, MD 20899-8263"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"33","published-online":{"date-parts":[[2008,2,28]]},"reference":[{"key":"2019100512401121600_c1","doi-asserted-by":"publisher","first-page":"178","DOI":"10.1007\/s003660070004","article-title":"A Model for the Flow of Design Information in Product Development","volume":"16","author":"Shooter","journal-title":"Eng.
