Jena and the OWLAPI have classes to translate from their native
representations to DIG.  Presumably anything that implements a DIG
client will have similar functionality.

Please be aware that the KR supported by DIG 1.1 is less expressive than
OWL DL, so the translation offered by Protege 3, or any other tool, is
likely to lose some information.  The expressivity of DIG 2 will match
OWL 2 DL, but at present there aren't DIG 2 tools.

Without knowing the cause of your OWL API / Jena prohibition, its
difficult for me to suggest other alternatives.

If the problem is a platform one (i.e., you're not using Jena and OWLAPI
because you're not in Java), perhaps you can consider using a bridge
from whatever your language is to Java.
