Next up was Guy Rixon who talked about the AstroGrid architecture. He pointed us to the architecture document which describes the architecture of the current iteration 6 release.
This was followed by a break away session where we sat down and talked about what we wanted out of AstroGrid-2 and what bits of the architecture needed tweaking. There was general agreement that, amongst other things, the portal is perhaps the real weakness of the current infrastructre and lets down an otherwise fairly good workflow system. A workbench system with an interface similar to Triana, or AVS, was suggested as a portal replacement.
