OIP protocol lineage
The line
Remote-operation protocols make operations addressable across systems. Each member of the line made one class of operation addressable.
- RPC made procedure calls addressable.
- SOAP made service messages addressable through structured envelopes.
- REST made resources addressable through URLs and methods.
- gRPC made typed service calls addressable.
- MCP (Model Context Protocol) made model-tool sessions addressable within a session.
- OIP (Object Invocation Protocol) makes model-operated work addressable as an object.
What OIP adds to the line
The OIP unit is a work object. The object states its contract, its scope, its invocation route, the receipt it produces, its replay path, and its repair path. The object carries its own proof: an action is established by its receipt at /api/dispatch?receipt=inv_ID.
Placement
SOAP standardized service messages. OIP standardizes executable work objects. A SOAP message describes a service request. An OIP object describes the work, its authority, its invocation route, its proof, its replay path, and its repair path.
