SOAPissa

SOAPissa is a fictional protocol specification that extends the Simple Object Access Protocol (SOAP) to address modern web service requirements. In this concept, SOAPissa maintains the XML-based message envelope of SOAP but introduces modularity and pluggable encodings to support efficient inter-service communication across heterogeneous networks. The design emphasizes contract-first development, using a WSDL-like interface description that can be bound to multiple transport protocols. It supports a pluggable security model inspired by WS-Security and modern authentication schemes, enabling message-level security, replay protection, and granular access control without mandating a particular transport.

Architecture and components include a message envelope, an optional encoding layer, a binding description, and a policy framework for security, reliability, and transactions. The envelope carries headers for routing, quality of service, and metadata, while the body contains the operation payload. Bindings can be HTTP/2, messaging systems, or alternative transports, allowing SOAPissa to function in service-oriented architectures and hybrid cloud environments. The project is used in academic and industry demonstrations to compare SOAP-based approaches with newer protocols and to illustrate potential gains in extensibility.

Note: SOAPissa is a fictional concept used for illustrative purposes in discussions of web service protocols and is not part of the standard SOAP specifications.
