Abstract

Methods and apparatus for information modeling, such as product modeling, are described. In one specific embodiment, a system for capturing product information includes a plurality of product trees and a plurality of configuration trees. Each configuration tree is associated with one of the plurality of product trees. At least two of the configuration trees share at least one usage configuration node, and the at least two configuration trees are associated with a same product tree. The at least two configuration trees share at least one occurrence configuration node.

at least two of said configuration trees sharing at least one said usage configuration node for sharing content between said plurality of configuration trees and thereby minimizing a number of usage configuration nodes used to capture the product information, said at least two configuration trees associated with a same product tree; and

said at least two configuration trees sharing at least one occurrence configuration node, for sharing content between said plurality of usage configuration nodes, to thereby minimize a number of occurrence configuration nodes used to capture the product information, said at least two configuration trees associated with a same product tree.

3. A system in accordance with claim 1 wherein each said usage configuration node may only be a child of said root definition configuration nodes that have an implement link to a common said root definition node, and the common said root definition node being a parent of a subset of said usage nodes, each said usage configuration node having an implement link to one of said usage nodes in the subset of said usage nodes.

5. A system in accordance with claim 1 wherein each said occurrence configuration node may only be a child of said occurrence configuration nodes that have an implement link to a common said occurrence node, and the common said occurrence node being a parent of a subset of said occurrence nodes, each said occurrence configuration node having an implement link to one of said occurrence nodes in the subset of said occurrence nodes.

2. A system for capturing product information, comprising at least one of a programmable computer and a server having a memory, said system further comprising within said memory:
