In architectural construction documents, elements may appear many times in the drawings but are only specified in one location in the project manual. To assure consistency and to know where to look for information, the American Institute of Architects (AIA) and Engineers Joint Contract Document Committee (EJCDC) established a Uniform Location of Subject Matter published in AIA Document A521/EJCDC 1910-16. Uniform subject matter locations for contracting and building the semantic world needs to be defined also.
What would be the most functional layout to show a full spectrum of information use in semantic space?
Curves and waves on axis like this diagram explaining Remote Sensing of the Global Environment by David J. Schneider in the Department of Geological Engineering and Sciences at Michigan Technological University
But how to accommodate and show various digital materials being transmitted, for example images, text, video, sound recordings etc. It may be better to establish a lay out similar to the electromagnetic spectrum as shown by the Division of Chemistry Education at Purdue University.
What about the pace information is exchanged? Perhaps quantum mechanics diagrams like this one by Alyssa A. Goodman at the Harvard-Smithsonian Center for Astrophysics would work.
