Publication summary

Author(s): Joshua Lubell

Publication date: February 2000

Citation: Joshua Lubell: "An XML Repository Architecture for STEP Modules," Proceedings of the World Automation Congress, Maui, Hawaii, June 11-16, 2000.

Key words: STEP, XML, module, repository, product data exchange


NIST is developing a web-based repository to serve as the core of a modular environment for developers of STEP, a family of product data exchange standards. Modules are represented in the repository as XML, enabling them to be treated both as documentation and as software components. A prototype implementation of the module repository uses XML and other emerging technologiecontent in a web browser in response to user input. No server-side processing is required.
