Hi Michael,
that's great! If [2] were to be updated with that [1] (i.e. officially
containing RDFa about these URI:s), and would be 303:d to from [3]
(along with anything under that URL), this would be all we need. I
know it hasn't happened for years, but sometimes a nudge at just the
right time may be all it takes..
If not, would you consider updating your interim solution to describe
URI:s under [1]? I mean, since [2] currently uses the real IANA URI:s
(i.e. the "unsanctioned" ones) and those, as Danny cautioned, could
end up e.g. being resolved to documents, breaking semantics (as well
as not being discoverable).
I did a manual (well, vim-macro:ed) conversion of [3] into RDF/XML,
but had to leave to eat easter eggs at my sister's and entertain her
kids. :) It's located at [4] now, and quite similar to the data in
[1]. Note that I do consider [1] much more interesting.
(That said, if anyone would like me to make e.g. an XSLT for turning
[4] into something like [1], just say the word.)
Best regards and happy easter!
Niklas

Niklas,
Nice!
I would once again suggest adding local "owl:equivalentProperty"
assertions which enables a reasoner to treat the IANA URIs as synonyms.
This is in line with what I like to call the: owl:shameAs pattern :-)

Yes. Use [1] ...
My motto is: acting rather than talking. So, I took [2] as a starting point
- which is already in nice XHTML format - and manually added some RDFa.
After an hour I ended up with [1] (though, to be fair, two Wii games with
the kids and consuming some Easter eggs also took place in that hour).
So, [1] is really a sort of an interim solution (though, in the distributed
data world I do expect much more of such fixes) and I encourage Phil, who is
an editor of [2] to use the template from [1] at the 'official' location.
Happy Easter! (and back to Wii games, for now ;)
Cheers,
Michael

Hi All,
Any guidance on using predicates in linked data / rdf which do not come
from rdfs/owl. Specifically I'm considering the range of:
http://www.iana.org/assignments/relation/*
Can't find a URL that resolves there
snap; but that's what rel="edit" and so forth resolves to.
see example:
http://www.w3.org/2001/tag/doc/selfDescribingDocuments.html#ATOMSection
and quote:
"If the relation-type is a relative URI, its base URI MUST be
considered to be "http://www.iana.org/assignments/relation/";

By using something as a predicate you are making statements about it. But...
If you can find IANA terms like this, please use them - though beware
the page isn't the concept. You might have to map them over to your
own namespace, PURL URIs preferred.
Would it make sense to knock up an ontology for all the standard
link-relations and sameAs them through to the iana uri's?
Best, Nathan
