[seek-dev] testing Ecogrid services in Kepler!?

Hi Bertram,

They already are being put into Kepler, but as part of the UI rather 
than as actors.  Adding them as actors too wouldn't be a problem, but it 
hasn't been our emphasis yet.

By selecting the 'Data' tab, typing a phrase, and hitting 'Go' you run 
an ecogrid "query".  Dragging a resulting data object to the canvas 
results in running an EcoGrid "get".  We have not yet exposed the 
"authenticate" or "put" routines, but soon we will.  Bing and Jing are 
working on getting the registry exposed in Kepler so that you can choose 
which EcoGrid nodes are searched and accessible, but for now the nodes 
are in a configuration file.  Eventually I'd like this interface to 
include all of the appropriate data access systems (e.g., JDBC, etc.), 
but for now its just EcoGrid.

Yep, I think that would be very meaningful.  We're close.  Of course, 
some EcoGrid systems support all of those calls (Metacat, SRB) while 
others only support a subset (DiGIR).  So the system needs to fail 
gracefully for those that don't.
