Michael F. Aube and Susan Post from Booz Allen & Hamilton had written a DAML/XSLT Adapter that allows conversion of an arbitrary DAML document into other formats utilizing an XSLT stylesheet. You can read more about it here. It's rather 'academic'-looking at the moment, but it is a promising project. For one thing, it'd allow conversion of DAML documents into a more simplified XML format which can then be parsed in restricted Java environments like PDAs.

I've been looking for a DAML parser that works on JDK 1.1.8 (which is the JVM version supported on most PDAs), but prolonged searches turned up naught. This seems to be a possible solution to my problems because the heavy-weight peer where the PDA gets the DAML document (wirelessly) from can instead convert it into a simplified XML format suitable for parsing on the PDA. Why parsing? It's to allow editing of DAML ontologies via a GUI. When transferring back, the conversion can be done the other way around, with total transparency to users at both ends. I'll be looking into this and will update on my experiences working with this.
