Once again, and as always, much depends on who the receiver is and what
the receiver expects. If the receiver expects an ordered list, then an
ordered list is all that is needed. If the receiver is a person, then
consider the case of outline editors. The whole purpose of an outline
editor is to make it easy to move parts of the outline into new orders,
and no person wants to have to track the order explicitly beyond the
visual ordering. Let the editing program handle the numbering or the
links, but behind the scenes.
Personally, I have set my text editor to display line numbers, for easy
reference, and that might sound like I contradict myself. But if I were
to output my text file in some simple xml format, one sentence after
another, I wouldn't bother to number them. Let the receiving program do
that, if needed.
Or consider what an awkward nuisance it is to order items in RDF. Of
course, a processor can always choose to ignore order, where present.
The "best" way may vary with receiver and application, but I would
rarely want to bother with having numbered annotation where order were
already built in.
Or concisely, DRY: Don't Repeat Yourself.
