Hello,

Hope the following helps. It is from the applescript list. I included 3
answers
and you may have to glean bits from each answer. It is somewhat related to
all
the threads about launch services, plists, protocols,.......

Nothing so complicated.  "applescript:" is just another URL scheme;
Script Editor registers itself as the default handler for that
scheme, and voila!  You can read about it at <http://www.apple.com/
applescript/scripteditor/12.html>.

The com.apple.scripteditor bit is mostly filler.  Exactly who gets
the URL request is actually determined by Launch Services based on
which applications say they can handle "applescript:" URLs.  You
specify that in your application plist; see <http://
developer.apple.com/documentation/MacOSX/Conceptual/BPRuntimeConfig/
Concepts/PListKeys.html#//apple_ref/doc/uid/20001431/TPXREF115> for
details.

As it happens, I just answered your question on-list.  (That's what I
get for reading my list mail first.)  Registering for a scheme is
simply a matter of adding it to your plist and then getting yourself
registered with Launch Services, which should happen automatically
when you launch the application.  See < http://developer.apple.com/
documentation/MacOSX/Conceptual/BPRuntimeConfig/Concepts/
PListKeys.html> under CFBundleURLTypes for details.  In your case, it
would look something like this:

CFBundleURLTypes = (
     {
         CFBundleURLName = "SimVRML";
         CFBundleURLSchemes = ( "simvrml" );
         CFBundleTypeRole = "Viewer";
     }
)
