Subject Re: Share database connections between annotators
Date Wed, 17 Sep 2014 11:54:25 GMT
My annotators aren't encompassed within an aggregate AE, but are chained
together in a CPE descriptor. Is it possible to define the external
resource in the CPE descriptor for the annotators to access, rather than
having bundle them into an aggregate in order to share the resource?
