It has been my experience that a lot of Domino shops want to enable some sort of coding standards, but they do not know where to start creating them. Also there are not any good examples that I have found available.
Over the years I have come up with a template I use when implementing coding standards in my organization. You can get them here.
This document is a good example of what you can do to create such a document. Use it as you see fit. If you do use it drop me a line and let me know how it worked for you. As always I will answer any questions you may have.
