Re: RDFa reliance on namespace declaration

Hello,

Another issue with copy-paste (not the authoring ease described by Ian
Davis), would be what happens when the user aggregates by copy-paste
chunks from several pages.

Google Notebook and Flock (in web snippets) discards RDFa, but other
tools may not (and probably they should not).

Flock and probably other "blog this" extensions will link back with
blockquote/@cite, other will just not provide the source; but for the
case the source is provided either by the copy-paste procedure, either
by a purple number, should a RDFa parser follow it and retrieve
namespace declarations?

Example:

<blockquote cite="http://benlog.com/">
If you quote content from this site, you should cite <a
rel="cc:citeURL" property="dc:title"
href="http://benlog.com">Benlog</a> by <span
property="cc:attributedTo">Ben Adida</span>
</blockquote>

Should a such extractor use the @cite as a breadcrumb and fetch the
original resource in the search of cc namespace? What if we already
have another cc namespace declared?

Cheers,
