RE: {Disarmed} AW: [geclipse-dev] Gria Information Gathered

Hi, Mathias, Nick,

Maybe I can clarify, there are two distinct pieces of information here
at different levels.

The first piece is an Application description which describes a type of
application that a Job Service offers.
A list of these applications URI's can be got from a Job Service using
the method 

String[] getApplications()

To then get the detailed information as seen below use 

Document getApplicationMetadataDetailed(String applicationURI)

In this case the job type is
'http://it-innovation.soton.ac.uk/grid/imagemagick/swirl'
And it has one input and one output


The second piece of information is from an instance of a data stager
which would have been created when the job was instantiated.
There is not the complete information here from what I can see, the most
important piece missing being the ConversationID which uniquely
identifies the resource on the service.
