General talk about software patterns

[Jacek Sokulski <jaceks AT software.com.pl>]

Hi Michael,
I am sure your patterns are great and maybe have some of QWAN. What I
mean is that the ideas like QWAN that in Alxander's work are central in
most discussion on software patterns are at most treated as something
marginal. In Alexander's pattern language the fundamental criteria if a
pattern is good is if it has the quality.
For example, I have not seen any serious research on what is QWAN in
software. After reading some Alexander's works I have some idea what it
is in architecture, but what it is in software? It took Alexander many
years to clarify his ideas, I am looking if someone has done similar
work in software.

Best wishes
Jacek
