Motivation

To establish common approaches across JISC eLearning projects for


The documentation of user requirements
The definition of web services
UML –Unified Modelling Language
Provides a standard vehicle for representing various
views of a system –




How it will be used
System Structure
The interfaces it provides
Its implementation
Used for


Motivation
Overall


The documentation of user requirements
The definition of web services
Using Web services
Facilitates co-operating between autonomous components


Spontaneously appear (and disappear)
– Require discovery mechanism
Autonomous evolution of a component
– Provided it supports the original definition
– Need a definition language
Therefore Must use WSDL –
Web Services Definition Language
Definitive, programming-oriented, documentation of the
service definition
