Re: [HTTP-range-14] Hyperthing: Semantic Web URI Validator (303, 301, 302, 307 and hash URIs)

Hi Yang et al,

Nice work :)

I really like the diagrams lower down the page showing the
relationships between the different resources. Contrary to Rob's
experience in another thread, I've never found people to have a
problem understanding the rationale for 303 redirects, in all the
"Intro to Linked Data" type talks I've done (for geeks and non-geeks
alike). Either way, this kind of visual explanation does bring a lot
of extra clarity, IMHO. Question: is there a better term than
"identifies" to label the arc between "Returned Document URI" and
"Number of Triples" at the bottom of the page.

On a practical note, your tool has helped me spot a bug with URIs such
as <http://rdfize.com/geo/point/52.47/-1.72/>, which returns only a
relative URI in the Location header. Perhaps you modify the tool to
catch this error condition and return a more meaningful response (I
currently get "Exception! IOError(2, 'No such file or directory')")?

Cheers,

Tom.
