Adaptive Services Grid
Adaptive Services Grid (ASG) is a reference architecture for the provision and orchestration of semantically described IT services ( Semantic Web Services ). The ASG was developed in an integrated EU project of the same name between September 2004 and February 2007, which was supported by the Sixth Framework Program of the European Commission .

Key results
- ASG reference architecture
- Proof of concept through a prototype for service integration and its methods
- Business scenarios for semantically described IT services
Service delivery lifecycle
The IT services registered with the ASG platform - in contrast to UDDI - do not represent a static set, but are constantly re-evaluated and, if necessary, supplemented by new services that are better suited to specific requests. These new services can come directly from known providers and only be used in new contexts, and they can also be automatically re-planned, generated, integrated and put into effect by the ASG platform. Both classic and dynamically generated IT services are recorded in the ASG registry. The service system runs through this service delivery lifecycle as soon as inquiries are made to the service platform that the platform cannot serve with the services that have been registered to date or are currently available. For this it is essential that all services provided by service providers have a suitable semantic description.
Domain ontology
The semantic description of the services at ASG is based on an ontology that is uniform within the domain . This domain ontology creates a kind of local standard for data exchange between IT services. This enables the ASG platform to capture the functionality and importance of an IT service within limits. At ASG, the domain ontology is written in the Web Service Modeling Language (WSML).
