Abstract:
This document is intended to help clarify the relationship of the JISC
IE architecture to 'service oriented' architectures such as those
adopted by the
DLF Abstract Services Taskforce
and the
e-Framework for Education and Research.
It starts from the
set of 'service components' shown in the JISC IE architecture diagram, extrapolating
a list of the 'abstract services' that are expected to be offered
and then listing a set of candidate 'service bindings' (that correspond with the
protocols and standards listed in the
JISC IE technical standards document.
This document builds on an earlier attempt to develop a
tentative
'reference model' for the discovery to delivery
space occupied by the JISC IE.
The previous document took a functional approach, using UML use cases to document
the anticipated behaviour of end-users of the JISC IE, then building up
a set of 'business processes', 'abstract services' and 'service bindings'.
However, the list of abstract services provided in the older document
is too simplistic and incomplete to be useful.
