This paper explains the features of SCA 1.0 and its applications. SCA 1.0 is a new technology for service componentization which has many unique features such as "Language Neutral", and "Recursive Composition". By leveraging uniqueness, SOA developers can use SCA 1.0 from high level design to low level implementation without a semantic gap and it also enables the reuse of existing assets for next generation applications.

Key Words & Phrases :
SOA, SCA, OSOA, component, BPEL, XML
