Notice that those tags are URIs. (At least, that's what the name of the attribute is.) People tend to confuse those things with URLs. A URI is a Uniform Resource Identifier, whereas a URL is a Uniform Resource Locator. As the latter article says, the two concepts are frequently confused.
In short, the URI is a name for a resource. That resource doesn't have to be located at any particular place; if it did, that would make the URI be a URL.

Thanks for your reply. I was ust trying to confirm that no internet connection means no problem, and you've confirmed -- since URI != URL.
subject: Are these tags OK to have with no Internet Connection?
