An open proprietary architectural standard is PROMOTED by Morris and Ferguson who MAKE CASE for open systems where the “complex of STANDARDS and rules” would be freely published. This open standard would allow anyone to see how the system was designed and constructed. This open-ended architecture would allow the software to evolve, because any enhancements to the software would have to adhere to a DEFINED architectural, and freely available, standard. An example of an open proprietary product is the CCITT fax standard and the NTSC television standard. An example of a closed proprietary product is Adobe’s PDF file format and Windows 2000 OS, as no one but the company can make changes to the architecture.
