Jeni's Musings

Something else to be thankful for: Google didn’t give anyone reason to believe that “v:” is a magic prefix, but requires a proper xmlns:v declaration to be parsed properly. Of course this is the right thing to do, but these days I don’t take that for granted.

Lately I’ve been thinking of the difference between URIs and URLs (besides URLs being a subset of URIs, like URNs) being that the former are Identifiers and the latter are Locators. If someone tells me that http://xxx is a locator, I expect to find something at that location; if they tell me that it’s an identifier, I know that it may just be a name used to distinguish that concept.
