This talk is about conceptual models for the e-Science infrastructure.  Why we need a conceptual model.  Here are some well known models a.k.a. architecture (each one attributed as appropriate).

This slide is from Keith Jeffery, CLRC, and has been doing the rounds for some time now - in some sense it characterises the UK vision.  Keith will say more in  his presentation.

This is the architecture shown by Bill Johnston at the EPSRC e-Science Town Meeting in July 2001.  Note the services layer. [BTW This is a gif of the actual slide, which takes over a Mb, so that this presentation fits on a  floppy]

The architecture from “Anatomy of the Grid” paper (this actual slide from EuroGlobus presentation)

One of many “wedding cakes” from W3C, a hook to Carole’s presentation (next) – I won’t talk about semantic web today.

The Web Services triangle , this particular picture from IBM.  Note the publish-find-bind model.

This is an IBM picture – note WSFL – Web Services Flow Language.  IMHO Flow is key to Grid.

By way of example, here is some workflow in the Grid context.
