Unique identifier for licenses

Many thanks for the reply. That's an interesting suggestion.
On the other hand, I'm a bit worried that these short form names don't
appear anywhere on opensource.org.
Any chances OSI could add them to
http://www.opensource.org/licenses/alphabetical ? i.e. after the license
name, have "(short-form = XXX)"
That would eliminate the reliance on another party that might diverge or
just not be updated when there is a license added by OSI.
I know this creates an admin burden, but given these guys seems to have done
most of the legwork, I think it would actually be a worthy addition to OSI's
offering (small, but with value).
(should I send this request to another particular group? I'm hoping OSI
folks are reading this list...)

Thanks,
