An Onion of Documents and Metadata

When a product cannot be tested as a finished unit, its warranty, as it were, depends on extensive testing of its component parts and assemblies. The record for products of the Y-12 National Security Complex has for many years been in the form of lengthy paper documents. Recently we have begun a process to capture some of this information in XML documents. However, this is not simply another XML publishing project. Because our products have a potentially very long shelf life and we cannot foresee the computing environment in their distant future existence, we must take extraordinary measures to document not only the products themselves but also the environment in which the documentation has been prepared. Adding complexity to this documentation challenge is a parallel effort to capture the output data of test equipment and wrap it in XML. While this project is very much a work in progress, we can see that one major component of its possible success will be the coordination of complex metadata.
