Tuscany is based on specifications defined by the OASIS Open CSAMember Section and the Open SOACollaboration:

• Service Component Architecture (SCA) - An essential characteristic of SOA is the ability to assemble new and existing services to create brand new applications that may consist of different technologies. Service Component Architecture defines a simple, service-based model for construction, assembly and deployment of a network of services (existing and new ones) that are defined in a language-neutral way. Tuscany implements the SCA Version 1.0specifications. Learn more about SCA

• Service Data Objects (SDO) provides a uniform interface for handling different forms of data, including XML documents, that can exist in a network of services and provides the mechanism for tracking changes. Tuscany implements the SDO Version 2.1specifications. Learn more about SDO

• Data Access Service (DAS) provides a simple SDO interface to relational databases. Learn more about DAS
