Abstract: Customer specific catalogs based on a set of standard catalogs are described. In one aspect, a computer-readable medium includes computer-program-instructions executable by a processor. The computer-program instructions are for implementing an application programming interface (API) to design and/or maintain an electronic catalog that is based on one or more base catalogs. the API includes a create catalog interface comprising a parameter to indicate that a catalog to be created is to be the electronic catalog, the electronic catalog being a virtual catalog.

Abstract: Generating and/or managing customer specific catalogs based on a set of standard catalogs are described. In one aspect, a catalog is generated or managed in view of a catalog schema data structure. The catalog schema data structure includes a first table The first table includes first, second, and third data fields. the first data field indicates a product, category, or variant of a base catalog to include or exclude from a virtual catalog that is derived at least in part from the base catalog. The second data field specifies an inclusion or exclusion rule to apply to the base catalog, product, category, or variant identified in the first data field. The third date if field provides an object ID of the product, category or variant.

Abstract: The described implementations generate a virtual catalog from one or more standard or base catalogs. To accomplish this, one or more virtual catalog customizing rules are presented and applied to content of one or more base catalogs. The applied rules incorporate by reference at least a subset of content specified by the one or more base catalogs into the virtual catalog.
