<snip> Also please note that if you mint your URIs using a 303-redirect service such as http://thing-described-by.org/ then the extra network hop from the 303 redirect could be optimized away by parsing the URI, as described here: http://thing-described-by.org/#optimizing For example, you would have the relationship:

<http://t-d-b.org/?http://example/toucan-page> :isDescribedBy <http://example/toucan-page> . </snip> So the solution is to introduce a URI convention (assigning meaning to the convention) and use a central service to implement this feature.

It is *a* solution -- not necessarily *the* solution. And if you don't want it centralized, there are ways to get around that also, which I discussed in 2005: http://lists.w3.org/Archives/Public/public-swbp-wg/2005Aug/0057.html

<snip> so if the toucan were denoted by the URI http://t-d-b.org/?http://example/toucan-page the you know that its description is located at http://example/toucan-page and there is no need to actually dereference the other URI. </snip> And to expect consumers of the URI to also understand and honor that convention.

That sure looks|sounds to me like a new URI scheme.

It is not a URI scheme as defined in RFC 3986: http://tools.ietf.org/html/rfc3986 It is conceptually similar in that it can define its own conventions and semantics. However, the key point is that it is *layered* on the good old http scheme. Thus, if you click on this URI:

http://t-d-b.org/?http://dbooth.org/2005/dbooth/

it works, with no changes needed to your browser. In contrast, if you click on this URI:

tdb:http://dbooth.org/2005/dbooth/

You get an error.
