From project page:
(...) Our goal within ICENI is to provide high-level abstractions
for e-science (scientific computing) which will allow users
to construct and define their own applications through
a graphical composition tool integrated with distributed
component repositories and to deliver this environment
across a range of platforms and devices.
(...) The distributed component repositories
will allow developers to contribute their software to the wider community
and easily incorporate other work into their own components or applications.
The ICENI middleware federates the underlying resources that enable
the e-scientist to carry out their work by allowing sophisticated
and extensible access and usage policies to be specified.
