OASIS SCA-C-C++ Technical Committee Publishes Two Public Review Drafts

Bryan Aupperle, David Haney, Pete Robbins (eds), OASIS Review DraftsMembers of the OASIS Service Component Architecture / C and C++(SCA-C-C++) Technical Committee have released two Committee Drafts forpublic review through March 25, 2010. This TC is part of the OASISOpen Composite Services Architecture (Open CSA) Member Section advancesopen standards that simplify SOA application development. Open CSAbrings together vendors and users from around the world to collaborateon standard ways to unify services regardless of programming languageor deployment platform. Open CSA promotes the further development andadoption of the Service Component Architecture (SCA) and Service DataObjects (SDO) families of specifications. SCA helps organizations moreeasily design and transform IT assets into reusable services that canbe rapidly assembled to meet changing business requirements. SDO letsapplication programmers uniformly access and manipulate data fromheterogeneous sources, including relational databases, XML data sources,Web services, and enterprise information systems."Service Component Architecture Client and Implementation Model for C++Specification Version 1.1" describes "the SCA Client and ImplementationModel for the C++ programming language. The SCA C++ implementationmodel describes how to implement SCA components in C++. A componentimplementation itself can also be a client to other services providedby other components or external services. The document describes howa C++ implemented component gets access to services and calls theiroperations. Thisdocument also explains how non-SCA C++ components canbe clients to services provided by other components or external services.The document shows how those non-SCA C++ component implementationsaccess services and call their operations.""Service Component Architecture Client and Implementation Model for CSpecification Version 1.1" describes "the SCA Client and ImplementationModel for the C programming language.

SCA defines a model for the creation of businesssolutions using a Service-Oriented Architecture, based on the conceptof Service Components which offer services and which make referencesto other services. SCA models business solutions as compositions ofgroups of service components, wired together in a configuration thatsatisfies the business goals. SCA applies aspects such as communicationmethods and policies for infrastructure capabilities such as securityand transactions through metadata attached to the compositions."http://docs.oasis-open.org/opencsa/sca-c-cpp/sca-cppcni-1.1-spec-cd05.htmlSee also the Model for C specification: http://docs.oasis-open.org/opencsa/sca-c-cpp/sca-ccni-1.1-spec-cd05.html
