Write some Web Services. Then describe them. Terse, but true :)

I don't know what web service kits are available on the palm. If 
there's an HTTP server, you could write a very simple "document" 
oriented web service (call it RESTy if you want to be buzzful), and use 
the WSDL2.0 HTTP binding to describe it.

Remember that OWL-S is a *description* language...what is described can 
be very different.

If you want to execute *compositions* of web services "directly" by 
examining an OWL-S composite process description...ok, then you have a 
bunch of issues :)

Despite my growing reputation on this group as a relentless shill for 
Evren's code, I still recommend the OWL-S API 
(http://www.mindswap.org/2004/owl-s/api/) if you do Java. The composer 
is a better "non coding" intro 
(http://www.mindswap.org/~evren/composer/) but it's a bit bit-rotted at 
the moment. I'm hoping a new grad student will be able to release a 
new, happier version before next term.
