David,

My understanding of an "open architecture" is one whose design specifications
and standards are publicly available, allowing many vendors to implement
systems compatible with the specification.  The opposite of an "open
architecture" is a "proprietary architecture."

Could you be more specific?  Are you interested in network architectures,
operating system architectures...

In the networks space, OSI (Open System Interconnection) is an example of an
open architecture.  It was (is being) developed by committees consisting of
many vendors.  The end result is an open networks architecture and protocol
suite that many vendors can implement, and (theoretically) have their systems
communicate with one another.

For networks one book to read is: "The Open Book: A Practical Perspective on
OSI" by Marshall T. Rose, Prentice Hall, Englewood Cliffs, NJ, 07632.  (c)
1990.
