Alan,

Thanks for that summary.

SWAN is not a software project - it is a project for a technology- 
mediated social infrastructure. Those fancy words mean we are trying  
to get the working scientists themselves to curate the material for  
their own benefit, self-understanding & "karma points".  We think it  
is the only sustainable & scalableway to represent hypotheses.

Nothing in principle - and I hope we can test this out - should  
prevent people who want to link very deep annotation of various kinds  
to SWAN hypotheses, from doing so.  But that is not our project. We  
are "just" providing the framework.  An essential criterion is that  
whatever we do is doable by working scientists and helps them to work.

Best

Tim
