Abstract:
The National Industrial Infrastructure Protocols (NIIIP) Consortium formed in 1994 to develop protocols to allow for manufacturers and their suppliers to develop products across the internet. The protocols selected and developed by the NIIIP Consortium have been validated in three end-of-cycle demonstrations. In each cycle, a team with expertise in technical product data, object modeling workflow management, security and knowledge representation came together and demonstrated how technical barriers to the dynamic creation, operation and dissolution of "virtual enterprises" are overcome by the NIII Protocols. This paper describes the barriers found by the product data team and the protocols that were selected and developed to overcome these barriers. >From the perspective of the product data team the challenge problem of the three demonstrations focused on multiple organizations supplying technical product data to a virtual enterprise. In Cycle 1 the operation for the demonstrations focused on multiple organizations supplying technical product data to a virtual enterprise. In Cycle 2 the operation was "engineering change"; and in Cycle 3 the operation was "create assembly." To enable these operations, the product data team had to make it possible for client applications to operate across the Internet in order to find, change, and integrate data belonging to a virtual enterprise.
