Systems based on the Service-Oriented Architecture (SOA) paradigm need to be able to bind to arbitrary (Web) services at run-time. However, current service frameworks are predominantly used through pre-compiled service access components, which are invariably hardwired to a specific service provider. We therefore implemented DAIOS – a message-based service framework that supports the implementation of SOAs, enabling dynamic invocation of SOAP/WSDL-based and RESTful services. It abstracts from all internals of the target service, allowing clients to be decoupled from services they use. DAIOS’ runtime performance is on par with the current state of the art and is therefore, a feasible solution for developers striving to implement dynamic SOAs.

DAIOS is implemented in Java (>5), and is the result of a research project of TU Wien.

Details on the implementation / usage of DAIOS can be found in the technical report.
