I've been watching the RDDL development with interest and optimism,
and finally had a look at the current draft of your (joint) work .
Although I think it's basically great, and I think definitely worth
pursuing, there's one aspect of this which has crept in un-noticed at
least by me, and I've been reading the threads pretty carefully:
The value of this attribute must be supplied and must a URI
reference. It provides a machine-readable identifier for the
type of the related resource. Software perfoming resource
resolution may dispatch on the this value."
so far so good
"When the related resource is an XML namespace compliant
document and when the resource can be distinguished by the
namespace of the root element, this namespace URI can be used
as the value of the xlink:arcrole attribute."
right, except replace 'can' by 'must' (see below)
"It is anticipated that many related-resource types will be
well known. A list of well-known resource types may be found
at http://www.rddl.org/arcrole.htm (which itself is an RDDL
OK, but why doesn't this file include the relevant namespace URIs, for
use as the value of 'arcrole' as the first two paragraphs suggest?
"The well known names defined in arcrole.htm are specifications
which they name."
Hunh? I can't make _any_ sense of this sentence. When I go to
arcroles.htm , I find statements such as
"The URI http://www.rddl.org/arcrole.htm#RELAX can be used as a
well-known URI for RELAX."
Why are you proliferating names which are _not_ well known, when
perfectly good ones exist, e.g. "http://www.xml.gr.jp/xmlns/relaxCore"?
The whole point of the RDDL exercise is lost if software has to keep
up with an arbitrary set of made-up URIs to identify resource types:
please identify _existing_ namespace URIs whenever possible, and open
discussion on this list for alternatives when no obvious candidate
exists (e.g. for CSS).
