Re: Use case template -- user needs

I realize that this is not in accord with FRBR, but I happen to favor  
this more complex view of user behaviors:
   http://kcoyle.net/temp/behaviors.jpg

Not all of them are primarily related to library metadata, but most of  
them could use library metadata for tasks that take place outside of  
the catalog. (One of my main criticisms of the FRBR tasks is that it  
assumes library data is in a library system silo, and doesn't  
recognize other uses.)
