Specification

Apache Tuscany simplifies the task of developing SOA solutions by providing a comprehensive infrastructure for SOA development and management that is based on Service Component Architecture (SCA) standard. With SCA as it's foundation, Tuscany offers solution developers the following advantages:

• Provides a model for creating composite applications by defining the services in the fabric and their relationships with one another. The services can be implemented in any technology.
• Enables service developers to create reusable services that only contain business logic. Protocols are pushed out of business logic and are handled through pluggable bindings. This lowers development cost.
• Applications can easily adapt to infrastructure changes without recoding since protocols are handled via pluggable bindings and quality of services (transaction, security) are handled declaratively.
• Existing applications can work with new SCA compositions. This allows for incremental growth towards a more flexible architecture, outsourcing or providing services to others.

In addition, Tuscany is integrated with various technologies and offers:

• a wide range of bindings (pluggable protocols)
• various component types including and not limited to Java, C++, BPEL, Spring and scripting
• an end to end service and data solution which includes support for Jaxb.
• a lightweight runtime that works standalone or with other application servers
• a modular architecture that makes it easy to integrate with different technologies and to extend
• Integration with web20 technologies

Apache Tuscany SCA is implemented in Java and C++ (referred to as Native).

Apache Tuscany also implements Service Data Objects (SDO) which 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 supports the SCO and the SDO (2.01 for C++ / 2.1 for Java) specification.
