Ahhh, semantics. Don't you just love it?
I vote to have this particular discussion

proposed for data types-$data
My counter proposal is that everything you say is good
except that I think it should be on $data not on $type. It seems to me if we
aren't going to coin a phrase that is explicitly $datatype that what we are
talking about is specifying a constraint, or rule, about the $data. Rules about
$type are defined in the dictionary.

RE: [xdi] Dollar word proposed for data

Cool
idea. $type is already one of our "default dollar words" by virtue of
being one of the XDI schema elements. And at first
blush this seems like a
good use of it. I also like the idea of making the
fragment identifiers in
the W3C Schema Datatypes spec the default.
I also suggest we go with true hierarchy, i.e.,
slash. This is what we did
with $l in the XRI Metadata spec - slash
delineates the instances of the
type, whereas * delegates to subtypes. For example
with $l, the immediate
children (i.e., if there is no delegated *name
after $l) are defined to be
two-letter language tags from (I forget the name
of the RFC - see the spec
at
http://www.oasis-open.org/committees/download.php/11854/xri-metadata-V2.0-cd
-01.pdf). For example:
$l/en
for English
$l/fr
for French
So with the $type space, we would specify (in the
Service Dictionary spec)
that the default child namespace under $type is
the set of fragment
identifier in the W3C Schema datatypes spec.
$type/string
$type/float
Then you could extend type definition to any other
namespace as follows:
$type*(=foo/mytypes)/custom.type
Sure meets the simplicity test. Thoughts?

or $type-yyy-xxx where yyy is the ident for a type
