<p>An object-oriented method of using a computer to store a model of an imprecise structure of a product. The product's components are modeled as items and item revisions. Each item and item revision has a view, which may have view revisions. Views and view revisions of an item or item revision are related to other with occurrences, as are views and view revisions of different items and item revisions. Context-specific view revisions are modeled as appearances. A user's request for a display of a product is received and used to invoke configuration rules that determine which view revision(s) are part of the product. The correct view revisions are assembled with their occurrences and appearances.</p> |
