(context: this was from the new rss-dev@egroups.com group where we're
discussing a proposal for an RDF/namespaces friendly v1.0 of RSS.
See http://purl.org/rss/1.0/ and the egroups.com for full'n'frank
debate... I was discussing some bookmark-sharing work happening at the
institute in which I work in Bristol.)

Seth: yes and no! This was initially at least an in-house experiment and
we don't have privacy clearance to flow the data more widely than within
the group of volunteers (who all know each other etc etc). Ultimately I'm
convinced that the future of bookmarks is in this kind of data flow, and
that it'll become a part of good webbery to allow non-private
comments/annotations/ratings to be exposed to the web at large. But that's
my personal hobbyhorse... (or one of them...)

The actual model for representing the bookmarks as RDF models is something
we're discussing. Libby Miller is doing the real work (and might 
be encouragable into summarising here) - I just scribble things on
whiteboards and handwave about it being in-essence the
same kind of data as sitemaps, channels and rating server data. I know
the issue of representing sequences and taxonomies came up, but we have 
a number of possible ways of projecting the browser-exported data into
a server-side RDFdb. Once it's there, idea is to encourage (through
collaboration tools, autoclassification, location-independence etc) people
to manage bookmarks/ratings/annotations serverside. The exact RDF model is
something that'll settle down over time. My inclination is to stash it all
as date-stamped events, eg 'on this data person foo recommended resouce
bar with comment blah etc etc', but other models are of course possible.

hope this helps,

ps. in a similar vein I started an installation of the http://crit.org/
toolsuite at W3C. Dysfunctional installation at http://crit.w3.org/ (my
fault -- I don't think the server has write access to disk so ratings get
lost). I want to testbed that as a public rating/comments server, eg. to see if we
can integrate it with the Amaya annotations work. Anyone interested in
helping with that? or with scoping where ratings/annotations stop and
shared bookmarks start... (all looks the same to me!)
