Not sure if this is off topic, but I was wondering whether it might be
useful to flip this around and look at things from the opposite
perspective of treating xhtml pages as remote data sources.

This is where Rails could potentially provide one hell of a jump start
for building distributed apps and microformats mashups.


Entry = MicroformatResource.new do |m|
    m.uri = "http://microformats.org/"
    m.schema = :hentry

entry = Entry.find_by_title("Steve Martin has an hCard")
entry.bookmark # >

Note, that if the schema symbol in this example was delegating to a
parser strategy (what's a better way to do this?), there would have to
be some kind of dependency chain that implicitly allowed for multiple
embedded microformats...

eg: :hentry => :hcard

In the hAtom case, the .author field must return an embedded struct of
hCard properties, or something similar (analogous to the
has_one/belongs_to relationship):

from the above example:

entry.author.fn # > Ryan
entry.author.url # > http://theryanking.com

Admittedly, this somewhat simple example raises a lot of weird
classname=>property mapping issues (eg: is it Entry.find_by_title or

Thoughts? Anyone keen to dive in and get this working? I haven't
looked at the source code for ActiveResource yet, but I'm sure it's
possible to figure out a much better design for doing pretty much what
I just described.
