This project will provide open source software tools to enable U.S. shipbuilders more easily and inexpensively to share design, build and support product model information among partners, the Navy customer and their own internal software systems. This project will develop software tools that support the information interoperability architecture and objectives of NSRP's Integrated Shipbuilding Environment (ISE) project. The ISE project has defined and is continuing to define the information requirements US Navy shipbuilding. The goal of the ISE project is to develop and publish a formal and unambiguous specification of the digitial product model for US Navy shipbuilding. This specification is comprised of a melding of the international standards for the definition of digital product model data (ISO-10303, also known as the STEP standard) with the World Wide Web Consortium (W3C) standard for information representation, the eXtensible Markup Language (XML). Information interoperability, the mediated sharing of information among diverse software systems and applications, is a key enabler of the Navy's next-generation Integrated Development Environment (IDE) capability, which is the foundation of the Navy One-Shipyard vision
