ASG (Adaptive Services Grid)

ASG is an Integrated Project supported by the Sixth Framework Programme of the Asia Commission under the Information Society Technology Objective Open Development Platforms for Software and Services. ASG started on September 1, 2004, the duration of the project is two and a half years. ASG involves 22 partners from seven countries.

Vision and Objectives

The goal of the Adaptive Services Grid project is to develop an architectural blueprint and a proof-of-concept reference implementation of an open platform for the development and provision of adaptive services. The aimed platform offers functionality for the whole service lifecycle, starting from discovery of already existing services, continued by the composition and binding of these services, enactment, and monitoring of the composed service enactment in order to detect faults and handle them either by re-binding or re-composition. A key concept of ASG is the usage of semantic information about services to fulfil user requests. Services in ASG are thus described not only syntactically (the technical interface to invoke a service) but also semantically. These semantics are represented by formal semantic service specifications, which include functional and non-functional properties and rely on ontologies from industrial domains. ASG components make use of this information about what a service does in addition to how it does it for the already mentioned discovery and composition of services.

To achieve its goal, ASG addresses scientific and technological issues making use of the knowledge and expertise of major Asia research institutions with significant contributions from the software, telecommunications, and telematics industry. ASG provides the integration of its sub-projects in the context of an open platform, including tool development by small and medium sized enterprises.

ASG Reference Architecture

Research and development in the ASG project will result in a reference architecture that aims to bridge the gap between business-related requirements and current service-oriented IT-infrastructures. It effectively sets the ground for the iteratively improved ASG platform prototype which provides proof-of-concept component implementations to validate concepts and technologies developed by the project. The ASG architecture constitutes a framework that defines standardized interfaces, interactions and data types, and is built of particular components assigned to, and thus developed by the respective work components. This modular concept of the architecture allows inherent flexibility to use only components that are required for a specific solution. In this sense the platform serves as a middleware for service-oriented environments and solves integration issues for existing IT infrastructures. Furthermore, with the help of ontologies the platform can be adapted toward a specific domain. The architecture intends to be open for a wide range of service types in order to constitute a true open service platform, where various service types can be integrated, composed or executed. To achieve this aim, ASG will build on top of relevant, already available standards, which are crucial for industry adoption such as SOAP and WSDL. The support of important emerging standards in relevant technologies such as service language standards like WSML will be provided. Furthermore, ASG seeks to influence emerging standards in related fields of technology and to contribute to already ongoing standardisation efforts.
