Figure 1 The architecture of IBHIS
The IBHIS system performs by supplying information services for the end-users. It delivers integrated data that
are gathered from distributed, heterogeneous and autonomous data sources. However, there is potential to extend it for
various aspects of service-based software, for instance data access control (Budgen et al., 2007). In addition, the service
negotiation function of IBHIS is only employed in establishing end-user access authorizations. To incorporate service
negotiation into IBHIS, therefore, it needs a negotiation framework which consists of three
fundamental elements:
message, protocol and decision model. Accordingly, the extension of the role of a
service negotiation function provides a
full range of service characteristics of service-based software.
Methodology
Research objective
The objective of this project is to develop and investigate a service-oriented broker system, called CAPTAIN
(Care Planning Through Auction-based Information Negotiation). CAPTAIN extends the concepts and role of the broker
used in IBHIS. In addition, it extends the service negotiation function used in IBHIS in order to demonstrate a full range of
service-based software characteristics: description, discovery, negotiation, delivery and composition. A service-oriented
broker architecture for CAPTAIN has been developed based on a case study by identifying the specific issues and
problems of the case study within healthcare context.
Research method
CAPTAIN use an integrated care plan within the healthcare sector to provide a research case study. The
clinician, who acts on behalf of the patient, finds and negotiates with
a number of service providers in order to satisfy the
form of a patient’s needs. The negotiation is employed for the service requestor and providers to agree on the terms of any
