[Esip-discovery] associating datasets with services in casts

[Ken Keiser]

One concern with these approaches would be that the information is probably not all-inclusive - in other word you are only getting a snapshot of data or services that some individual or entity knows about.  Isn't this really a classic semantic inferencing problem?  The final destination of the results might be the various casts, but the service to derive the information would seemingly need to be more dynamic.
