Re: [Locators] Re: While it is still fresh in our minds: '!' is not just a funny fragment identifier...

I share Ivan's responsibility, as I was the one who made the (obviously) unclear comment during the call in the first place :-)

But I agree with Nick, this thread was useful to clarify some technical bits, even if it's too early to discuss technical solutions to a problem that is not well-defined yet.

I was unaware of ! and I think it would be useful for PWP as it maintains the idea of a package, and things following the ! are part of the package.  Hope others are more clear on this as well.  Creating confusion is also the best way to gain clarity.

I've never actually seen ! used in a URL or URI so I'm having some difficulty understanding it's current use.

The meaning of these 2 sub-components and what the server is supposed to do with them is not generically defined, but one can reasonably expect that the fact that the path has been divided into sub-components make this URI different than say http://example.org/myRoot/A-B <http://example.org/myRoot/A-B> where the path has not been divided into sub-components (because '-' is an allowed but not reserved character in URL syntax. Certainly if you wanted to referred to the font file of a PWP resource held somewhere separate from the rest of the PWD, using the base locator of the PWP, it could make sense to do so by appending its name as a path sub-component, though of course this would have to be clearly spelled out and uptake would be uncertain, and there are other approaches as well.  But starting with a reserved character does seem like a good idea.
