The OASIS Open Composite Services Architecture (Open CSA) Member Section advances open standards that simplify SOA application development. Open CSA brings together vendors and users from around the world to collaborate on standard ways to unify services regardless of programming language or deployment platform.

Open CSA promotes the further development and adoption of the Service Component Architecture (SCA) and Service Data Objects (SDO) families of specifications. SCA helps organizations more easily design and transform IT assets into reusable services that can be rapidly assembled to meet changing business requirements. SDO lets application programmers uniformly access and manipulate data from heterogeneous sources, including relational databases, XML data sources, Web services, and enterprise information systems.

Everyone is invited to participate in the work of Open CSA, which is produced under the OASIS open standards process. Open CSA encourages the proliferation of compatible implementations by providing its specifications to the community on a Royalty Free basis.
