Re: resources

the descriptions are intended to be machine readable in the simplest possible
form, parsed trivially, and that form works well.  internally it's held as list of (string, string)
in an adt so there's not much point in adding extra punctuation.
originally i'd suggested using ndb's format (and indeed we can load ndb format directly
into the registry to bootstrap it as required) but roger argued otherwise and i think he was right.
it's easy to extract data using grep and the shell.  (roger originally allowed newlines
in it but that messes up most tools, so there i think he was wrong, and we don't put them in.)
there are some Tk applications that display and edit it in various ways.

it's worth noting that a given value can be structured, using any suitable notation you like,
including sexpressions if you need them.  i'm interested in examples.
