I suggest webmaster aliases for server-wide responsability and
a typed link for authorship of any given document. Many
servers provide stuff from many areas, one person is not
responsible for everything. Our local mainframe doc system
has a function key dedicated to "who is responsible for the runnish
on my screen?!" function. This is important for up-to-date info,
accountability.
I see this as one good use for a link type. Something I have
wondered about a lot is a namespace for people in the URL scheme.
You can even find something about them using SMTP if they
are on the internet.

Following the link would give options of mailing the person.

You mean http2 or html2?

I think we are allowed to let lines cross. Just than minimising the
number of crossings (the "badness") is almose certainly np complete
But in fact a tree will probably be less confusing for people.
I like history trees like
AAAAAAAAAAA
BBBBBBBBBBBBBBB
CCCCCCCCCCCCC CCC C
DDD DDDDDDDD
EEEEEEEEEEEE
AAAAAAAAAAAA *
BBBBBBBBBBBBB *
FFFFFFFFFF FFFFFF
DDDDDD *
GGGGGGGGGGGGGGG
wheer * indicates that the links from that node are listed at a same
or higher level in the tree. (You could give line number
cross-refernece or a link to the listing). This is gives the real
user the comforting illusion that (s)he is playing with a tree, which
people seem to find easier to remember than a web.

Where do we find the HyTime folk's thinking online?
