The Current State of the International Standard for Exchange of Optical Data in Electronic Form

摘要

The International Organization for Standardization (ISO) is developing a standard for the exchange of optical data in electronic form between different design programs. In order that the data be completely unambiguous an on-line Properties Dictionary is also being established, when finished this should be available to subscribers to ISO and will enable optical designers and manufacturing industry to access information accurately and transfer this information without manual intervention, across many boundaries. The Neutral Optical Data Interchange Format (NODIF) will use this dictionary to define the optical data that can be passed between to any CAD programs that are STEP compliant. NODIF is of concern to software developers, the Properties Dictionary is of concern to manufacturers.
