bringing Mark up to speed on the @prefix discussion from last week
scribe: no need to confuse things with prefix="=u1"
Mark: agree on this need not to confuse things
with prefix="=u1"
... agree on concept of prefix="p1=u1 p2=u2", but may argue about specific
attribute name, a bit uncomfortable with = inside attr
Ben: colon instead?
Shane: hah!
... don't know that anyone's had this particular assignment problem before.
... XSLT?
Mark: they don't use "="
... schemaLocation? space-separated values
... haven't finished the "bundle idea" writeup. Not until new year.

Ben: talked last time about using RDF to map tokens to full URLs
Mark: yes, see example above
... critics will say that this looks too complicated.
... so take xmlns declarations out into different document.
Ben: worried about how existing RDFa might generate new triples later.
Mark: don't have a problem with a different
syntax, as long as we have this tokenization approach.
... could be a feature of only @prefix or @token
Shane: is there a follow-your-nose story here?
Mark: still working on that.
... trying to make it as close to microformats as possible, but they're not
completely consistent.
... trying to leverage existing microformat work + XDMP
Shane: description of a way to do this with
extended XMDP mechanism
... on wiki
Mark: would be good to have a full follow your nose
Ben: I like the idea that a single attribute would provide both the ability to define prefixes without xmlns *and* the new token feature for bundles of terms
<markbirbeck> a:b a x:y .
Mark: if you know the context of something,
then why bother with a:b.
... letter a is fine if you've got context.
... it's good to move away from the qname world to a token-mapping world.
... maybe a good reason to call it @token rather than @prefix.
recursion when datatype is xmlliteral
CONSENSUS: we agree that when datatype is plain, recursion continues, when datatype is xmlliteral, recursion stops.
@about on head
problematic example:
<html about="#foo">
<head> <link rel=...></head>
</html>
<ShaneM> http://www.w3.org/TR/rdfa-syntax/#sec_5.5.
<markbirbeck> "If no URI is provided by a resource attribute, then the first match from the following rules will apply:
<markbirbeck> if the element is the head or body element then act as if there is an empty @about present, and process it according to the rule for @about, above;"
<markbirbeck> In 5.5
<markbirbeck> step 4
