I should clarify my intention here, which is that each DOI is mapped behind the scenes by Perl to a standalone absolute filesystem url, and when you define one DOI in terms of another, their definitions are *not* bound together. For example, if you define DOI "b" as subdir "foo" of DOI "a", and then you later redefine what "a" is, then "b" does *not* automatically update to be the "foo" subdir of the altered "a", but rather keeps its original meaning. So this keeps things simpler and avoids action at a distance. Well the only "action at a distance" is that any subsequently executed code with a p{a/bar/baz} will use the new meaning of "a". -- Darren Duncan
