		     BoF (Birds-of-a-Feather) BoFs are an opportunity for informal, relaxing discussions on topics
		      of interest in the patterns community. Anyone can propose a BoF
upon arrival at PLoP. These are the ones that are happening so far: Patterns and Symmetry: The Role of Symmetry in Architecture and ProgramsThere is a lot of talk about this, but what is it all about? Dick Gabriel
		      and Ali Arsanjani will lead a discussion that promises to be very thought-provoking!  Pattern FormatsWhat formats are pattern writers using? Do we have too many? Is there
		      one format that is “best”?  Rules versus Patterns What is the difference between a
		        Rule and a Pattern?  What role(s) do Rules play in Pattern Mining?
		      Can Rules indicate Patterns?  Can Patterns indicate Rules?  Are both
		      Rules and Paterns structured? Is there agreement within the Pattern community
		        on the differences between Rules and Patterns ( No ).  Can the
		      Pattern community arrive at a consensus position on the differences between
		      Rules and Patterns that can be succinctly documented and communicated?
		       David Hecksel will lead this interesting discussion.    If you wish to get your BoF idea on
		        the web page before PLoP, email a title and short description to
