Abstract: OGSA-DAI is a widely used middleware infrastructure, aligned with the Global Grid Forum’s (GGF) OGSA vision, to facilitate uniform access to data resources using a service-oriented architecture (SOA). It is intended to provide a reference implementation of WS-DAI. Initially OGSA-DAI was based on the OGSI infrastructure but recent releases support WS-I, WS-I+, and WSRF. The change to these new specifications raised new issues and requirements. It has been taken as an opportunity to review all aspects of OGSA-DAI. This paper describes the new architecture for future releases and its rationale.
