[Xml1-wire-devel] Requirements

[Sean K. <ke...@ad...>]

Folks:

I'd like to firm up what the requirements are for
tagging.  I've got my own ideas of what I'd like to see
out of a tagging API, and those are probably different
from others' (I came into the 1-wire world for home
automation).

For example, what exactly constitutes a tag?  Is it
merely a binding between a 1-wire address and an
arbitrary object?  Or are the contraints on the tag?
If so, what's the metadata of the object?  What's the
lifetime of the binding?  What constitutes a cluster?
Is there a relationship between stems, branches,
trunks, and busses to clusters, and should that
information be captured and managed?

Answering these questions can help lead to a set of use
cases, nonfunctional requirements, and the XML DTD.
And, groan if you must, that's something that's
important to document.  (Don't worry: I enjoy
documentation.)  I think Byron's got some interesting
ideas captured in his initial DTD, and that's got my
wheels turning (I'm normally asleep at this time after
all), but creating an information schema without
understanding its requirements means you can paint
yourself into a corner later.
