A simple (possibly dumb) question. Is there a standard mechanism for
linking an HTML page to the non-information resource that it
describes?
Um. OK, I have an equally dumb question in response. What does it
(what can it possibly) mean to *link* to a non-information resource? I
have been understanding the usage of "link" to mean that a link is a
URI which both refers to the thing being linked to (the linkee) and
also provides access to it when used in an HTTP GET. But this latter,
of course, exactly what is impossible to do when the linkee is a non-
information resource, pretty much by definition.
Do you mean, a standard mechanism to *refer to* the resource? Because
surely that is done simply by *using* the URI which names it. It
requires no other 'mechanism'; indeed, I don't think that there
possibly could be a mechanism for reference.
For example, in the page
<http://dbpedia.org/page/Mogwai_(band)>
I see a number of <link> elements in the header that point me to
alternate representations (rdf, json etc). There's nothing in the
header that points me to *<http://dbpedia.org/resource/
Mogwai_(band)>* (as far as I can tell) though.
But there is an owl:sameAs which links to http://mpii.de/yago/resource/Mogwai_(band)
, which appears to be a use of a URI referring to the non-information
resource. Is this an example of the kind of link you are looking for?

There is an "about" attribute on the body that does so:
<body onload="init();" about="http://dbpedia.org/resource/Mogwai_(band)
">
...
In contrast, if I look at the page for the band on the BBC, i.e.
<http://www.bbc.co.uk/music/artists/d700b3f5-45af-4d02-95ed-57d301bda93e
>
there seems to be no reference at all to the non-information resource
<http://www.bbc.co.uk/music/artists/d700b3f5-45af-4d02-95ed-57d301bda93e#artist
>
which is the "subject" of the page.
Any conventions in operation here?
Thanks,
Sean
