I was of course excited by the appearance of the news article about
OpenCalais in the esw wiki.
So like many of us, I hope, I trundled over there to see if I could do some
linkage to it from my LD.
Having failed, I guess my question is, how do I find the URIs in Calais so I
can link to them?

A more detailed account:
I hope I am doing something wrong, as I found it quite hard.
Well actually impossible.
Here are some of my difficulties:
I started by following the given IBM link.
This indeed does 303 to either html or rdf+xml.
But what is returned is not really very linked.
I could find no interesting URIs - both versions of the page are almost
entirely made up of strings for the resources I might have cared about.
And the URIs that are there for the headings seem to get me to a "Requested
URI not found".
So I tried another tack and went searching on Calais itself (for
"Berners-Lee" of course), but this did not reveal anything that could be
described as a page or other identifier that I could use to get to
information about him. But then I realise that neither does searching for
"IBM".
I then found the release notes at
http://www.opencalais.com/files/RelNotes_09Jan14_0.pdf
which do have another URI for Paris, and this has some sameAs links
eventually, but I still can't move around the Calais space.
So I am sitting looking at the example IBM and Paris pages, without a clue
how to get any further.
(Well I have one clue, which is to register, learn the whole API and start
making calls, but I am sure there must be a better way.)
Anyone got any further?
And while we are at it, does anyone have any idea why they don't use URIs
for the entities on the pages?
The IBM page has a reference to Microsoft - they must have a URI for it, but
they just give the string.
This must be a brilliant resource if I can only link to it!
Best
Hugh
