Many interdisciplinary research projects lie at the basis of valuable information resources in the form of measured and calculated data, reports, publication, etc. These resources, however, can usually not be used over extended periods of time as they are bound to specific software, or because specific information, such as data sources or calculation principles, is missing. A partial solution to this problem could come in the form of a platform-independent archiving of scientific information. The XML format, which was originally developed for internet data, including the extensions for the scientific area, could be useful here. The second part of the problem can be solved by the integration and networking of information resources. This can be achieved in various ways, some of which are described here to provide a framework for the documentation of interdisciplinary research projects.
