real oversight or reporting requirements should be shocking, but it isn't. The courts ruled in 2005 that law enforcement doesn't need to show probable cause to obtain your physical location
via the cell phone grid. All of the aforementioned metadata can be accessed with an easy-to-obtain pen register/trap & trace order. But given the volume of requests, it's hard to imagine that
the courts are involved in all of these.'

I'm a big fan of the concept of registerProtocolHandler in HTML 5 and in FireFox 3, but not quite the implementation. From a high level, it allows web apps to register themselves as
handlers of an URL scheme so for (the canonical) example, GMail can register for the mailto URL scheme. I like the concept:
- Better integration of web apps with your system.
- Its easy for web apps to do.
- Links to URNs can now take the user to the sites the user prefers for the sort of thing identified by the URN. For example, if I have a physical address in HTML, instead of making that an http
link to Yahoo Maps, I can make the link a geo scheme URI and those who follow the link will get their preferred mapping site that
has registered for that scheme. Actually, looking at the geo scheme's RFC, maybe I'd rather use some other URN scheme to represent the physical location, but you get the point.
However, the way its currently spec'ed out I don't like the following:
- There's no way to know if you are the handler for a particular URL scheme which is an important question for web app URL protocol handler authors.
- There's no way to fallback to an http URL in the case that a particular URL scheme isn't registered. A suggested solution to testing the registration of a scheme is for browsers to provide an additional script method
to check if a scheme is registered. I don't like the idea of writing script that walks over all my page's links and rewrites them based on that method. I'd much rather see a declarative and
backwards compatible fallback mechanism, although I don't know what that would look like.
- There's no way to register for a namespace within the urn scheme URI, the info scheme URI, or the tag scheme URI. I want to register
info:lccn/... (Library of Congress Card Number identifiers) to LibraryThing or Amazon and I want to register urn:duri:... (dated URIs) to the Web Archive, among other things.
- Will this result in a proliferation of unregistered URL schemes with clashing namespaces? The ESW Wiki notes why this would be bad.
- And last, although this is nitpickier than the rest, I don't like the '%s' syntax used in the registration method. I'd much rather pass in an URL template, like the URL template used
in OpenSearch. If an URL template is used for matching rather than registering against a particular URL scheme, this could also allow for registering a namespace within a URN. For example
something along the lines of:
registerProtocolHandler("info:lccn/{lccnID}", "htttp://www.librarything.com/search_works.php?q={lccnID}", "LibraryThing LCCN")
