software application and the file system where application states and state
changes are recorded in log files.
Chapter 19 (Multi-modal interaction framework) presents a middleware
framework that supports the development of large concurrent and distri-
buted systems. This case study abstracts the common features that charac-
terize distributed systems developed in Part III of this topic with the aim of
building a software infrastructure that provides mechanisms and abstract
classes for remote service creation, allocation and execution.
Chapter 20 (Negotiation-based service configuration) exemplifies the
development of an agent-based service framework that enables automated
negotiation of service execution contracts between service providers and
service customers. The framework extends the multi-modal interaction
framework presented in Chapter 19.
Chapter 21 (Workflow management system) deals with the development
of a workflow management system (WMS). A WMS is an example of grey-box
enterprise framework that enacts application-specific business processes.
Customization is performed using a suitable process definition language.
Enactment consists of assigning the right task to the right person at the
right time and ensuring that it is carried out within the required deadline.
A standard interface for monitoring and controlling processes is adopted. A
proof-of-concept interface is developed making use of web-based techniques.
