But Yelp has to understand the URI scheme.  That means it has
to parse it and do something useful with it.  It can't just
magically guess what each part of the URI means.  Somebody
has to write code to make Yelp do that.

Registering a URI scheme is one thing.  When you register a
URI scheme, you're telling Gnome what program to launch when
a URI of that form is encountered.  And it seems you've done
that successfully.  But you can't just send a URI to a program
that doesn't understand that kind of URI.  That's sort of like
expecting an image viewer to grok some new image format you've
just made up.
