OK. This is one view of hypermedia, and I'll get into this later.

In fact, I do not mean these. When I say "query" I mean whatever
follows after the "?", and in particular, the results of a forms

Now, the kind of hypermedia viewpoint you are espousing is that in
fact, everything is a query. I see this as one viable approach. I
gather from your message that you use fragment specifiers a lot, or
perhaps queries (in my sense of the word). However, something like




can, and, I believe, should, be treated differently. In the first case,
you have what is effectively a deterministic address, in the second
case you are dealing with user input. The addressing can be
accomplished in a number of different ways: 


for example. Such addresses can be written down.

In the case of user input, what is being sent to the server is
(and should be) transparent to the user. I argue that user input
should be treated as a seperate chunk of data, and a seperate *type*
of data. It is not an address.

There are cases, obviously, where people might go off, execute a
search, and find something interesting to pass along to a friend. In
such a case, some people would argue that you should be able to write
down the URL *including* the query. I disagree, and think that there
are better ways of accomplishing the same thing. In a reasonable
hypermedia system, you should be able to create, and name, a query link
that people can link to.
