Are you talking about listing each property seperately in their
own link statement? Or a link to a file describing the URI schema
in use for the properties of that page?
The former, I think; otherwise, it becomes difficult to "identify
each individually update-able resource with its own URI."
Clarified at: http://microformats.org/wiki/rest/property#
The reason I ask is this then sounds suspiciously like the meta tag
with some server updating code tacked on.
Ah, here's the difference. "relProperty" is a *pointer* to a value,
which lives in a different resource. The meta tag is an "immediate"
variable (if I have my terms right): the value is embedded within the
document, and thus can't be updated independently. This harkens back
to our extrinsic vs. intrinsic metadata issue.
I've tried to make that clearer at: http://microformats.org/wiki/rest/
property#relProperty
I'm not clear why ";" creates hierarchy problems? My gut-level
interpretation would be:
;prop1;prop2 are chained properties
;prop1/subprop1 is a "hierarchical" property
That is, we just reuse the existing HTML hierarchy separator.
What would be the problem with that?
Ambiguity
http://example.org/test/books;citation/author=Breton;title=example
is author a subproperty of citation, or a subdirectory of books?
Is title a child of citation, or a child of books?
I think we may be talking past each other. I fully agree that just
saying "; is a separator" is ambiguous. That is *why* this is an
open issue -- we need to fully specify exactly how those corner cases
need to be handled. To be sure, that is a lot of work -- but
(assuming we accept the need for hierarchical properties) *that* work
has to be done, regardless of the encoding used.
Rather than argue in the abstract, let me suggest some _possible_
rules for how chaining and hierarchies could work:
http://microformats.org/wiki/rest/property#.3Bproperty
I'm not happy with them, but its just a starting point -- alternate
suggestions are welcome! Again, if you think about this as replacing
WebDAV, not "meta" tags, the usage scenarios might make more sense.
Any thoughts about how to make that distinction clearer would be
greatly appreciated.
Thanks for the feedback!
