Managing technical illustrations in digital formats

The CALS Engineering Information Management Office at Fort Meade, Maryland—a division of the Information Systems Security Organization (ISSO) of the National Security Agency (NSA)—has developed a centralized digital library to replace the physical library. Now, customers have instantaneous desktop access to any document stored in the digital library. Graphical documents are stored in a variety of formats. An important component of the digital library is the capability of online evaluation of engineering change proposals (ECPs), which are prepared by agency contractors. The new digital library makes all of these change proposals immediately available to qualified users throughout the Information Systems Security Organization (ISSO). Physical location and storage of documents are now transparent. Allowing many different types of graphic formats made it necessary to identify a viewing tool that would be capable of handling all of the required formats. The CADleaf package met the basic requirement of supporting all graphic formats contained in the digital library.
