Organisations are increasingly using the Web to provide their services to businesses and individual customers. Thus, it is becoming increasingly important that Basic Services (BSs) offered by individual organisations be available, scalableand adaptive. And the presence of numerous BSs over the Internet is creating a new business opportunity for providing value added, inter-organisational services by composing multiple BSs into Composite Services (CSs). What is needed to enable this goal is an 'Internet Middleware' that establishes a common standard between organisations for composing services. ADAPT will develop the technology and software infrastructure necessary for defining, enacting, and monitoring interenterprise business processes that are implemented as CSs with guarantees of availability, scalability, security and adaptability not only to changing network conditions and user requirements but also to reconfigurations and repairs.
Objectives:
ADAPT will develop the technology and software infrastructure necessary for defining, enacting, and monitoring inter-enterprise business processes that are implemented as composite services with guarantees of availability, scalability and adaptability not only to changing network conditions and user requirements but also to reconfigurations and repairs. ADAPT will also provide middleware support for available, secure and dynamically adaptive basic services that will be used to build higher level composite services.
Work description:
The presence of numerous basic services over the Internet is creating a new business opportunity for providing value added, inter-organisational services by composing multiple basic services into composite services. ADAPT will develop the technology, software infrastructure and a working system capable of defining, enacting, and monitoring inter-organisational business processes and supporting related coordination activities.
The results of ADAPT will be open source and of interest to wide scientific and industrial communities, and will include:
1) Tools for creation of self-descriptive basic services built over commonly-used middleware;
2) an inter-organisation middleware platform for composite service creation and management, allowing enterprises to publish the services they provide, use services available globally in a secure manner as components of a composite service, specify its structure in a graphical programming language, automatically compile the description into an executable process, and deploy and monitor the execution of such composite processes. The middleware platform will contain re-configuration and self-repairing features to enable a composite service to adapt itself to changes caused by insertion or withdrawal of services, changes in network conditions and changes in user requirements.
The project will develop demonstrator applications; the main demonstrator being a long running one (such as a travel planning e-service) through which the project will demonstrate composition, monitoring, management and dynamic adaptability to various changes both in the execution environment and in the system configuration. The migration of ADAPT results and technologies to industry as well as into standards will be supported by active contribution to the standardisation efforts within OMG, J2EE related Java Community Process and Web services activities of W3C.
