These specifications are to enable language-independent components in an SOA. the Tuscany project provides implementations for various programming languages , such as C , Java and PHP, ready.
The SCA specification is supported by a body of OASIS ( Organization for the Advancement of Structured Information Standards) standardized, SDO and DAS specification of the OSOA (Open Service Oriented Architecture - an association of software manufacturers ) developed.
