DARPA sponsored CoSAR-TS
project is used as a testbed for experiments with semantic services
and inspiration for new technology development in this area:
Two tools integrating semantic services with the KAoS
Services, especially its policy part, are currently under initial investigation
and design:
I-K-C is a prototype tool in the initial stage of development
enabling composition of Semantic Web Services into workflow taking into
account policies constraining usage of these services and their composition.
The tool is developed in collaboration with AIAI
and integrates the I-X
technology. At first, this tool is going to build a workflow from the
client perspective taking into account only its policies, constraining
usage of different services and their composition, when building the
workflow.
Semantic Firewall is developed in collaboration with IT
Innovation Centre of University of Southampton and SRI.
The planned tool will take as an input a desired client workflow and
starts negotiation with the policy services associated with semantic
service provider intended to be used in the proposed workflow. In effect,
the initial workflow can be modified and amended with the agreed policy
contract. This contract will be then enforced by the system.
An Integration of these two complementary tools is envisioned
for the next phase. The resulted combination can use I-K-C to produced
initial workflow and then negotiated a policy contract and enforced
it by the Semantic Firewall. Further development may combine these two
tool even closer by interleaving workflow planning and policy negotiation
phases.
KAoS is also proposed to be used in the currently being designed Trust
Infrastructure for Semantic Web Services (restricted
access).
