OK I'd have expected to see the following after thie CONFIG-END block:

ACTIVITIES
END
dataResourceClass=DATA-RESOURCE-CLASS

where DATA-RESOURCE-CLASS is the name of the OGSA-DAI data resource
plugin class that you have written that handles communications with your
OWL resource.

(see 17.2.4.2 and 17.2.4.4 - and, yes, sorry, these sections could be
clearer in their explanations.

On a separate note all the entries in the PROPERTIES-END block are exposed
to clients as resource properties so you'd be better declaring these in
the CONFIG-END block as resource configuration properties.

Cheers,

mike
