Yes, I think proposals are non-conflicting, essentially my proposal
just adds whole lot of bells and whistles. I feel that Suzan's leaves
too many things open, and non RDF-guru developers have to figure out
on their own and we may end up with non-compatible implementations.

Couple of questions they might have:

1. How one specify alternative formats? This is the most frequently
asked feature.
2. How one specify multiple enclosures?
3. How one provide information about which of alternative formats are
most preferable?

I can put forward sample use-cases where all these features are
needed.

Current version of Suzan's proposal does not address #2 and #3.

I also disagree with her approach on BitTorrent. Looking at her
example, you will notice that BitTorent version of enclosure does not
provide any information about content type of an object. Imagine you
have audio file in several formats, all distributed with BitTorent.
Following Suzan's proposal they will differ only by URL. So you need
to actually download them first to figure out which one you want.

Then come "nice to have" things, like "rel", "location", "ContentID".
 Yes, they are obvious and RDF allows to attach these and countless
other things to enclosure anyway. But I think these are some people
will need in first order, and offering to them a standard way of
representing them will simplify their life a lot. Imagine yourself in
the shoes of developer of RSS-based application: he might not even
know much about RDF and would not have motivation and time to figure
out how to define say, "location" property, that it is good idea to
make it sub-property of dc:coverage and what are RDF formats for
spatial information representation are out there he can use. We did
this job for him.

I really do not want to sound like I criticizing Suzan's proposal in
order to push mine, but as developer who have need to use something
like this right away, I just need to see proposal which provides
certain level of functionality right now.

Sincerely,
Vadim
