elemenope is an Enterprise Application Integration, Service Oriented Architecture, and general messaging framework. It provides the capability for massive decoupling of an enterprise's components through standardized interfaces for communications. It provides complete abstraction of both transmission protocol and functional components. A project may connect components via a particular protocol standard, and completely change the protocol technology deployed with a simple change to a configuration file, i.e. no code changes. It implements the following connector sets: JMS, SOAP, XML-RPC, direct call, and native IBM MQSeries. It allows an organization to easily create a large scale multi-platform application to conduct messaging or transaction processing. It simplifies architecture of large systems by standardizing functional components and message pathways.
