OCOM Core Vocabulary

Contract

The OCOM Specification defines Contract as

A Contract is a governed agreement between two or more Objects.

Definition

A Contract is a governed agreement between two or more Objects. A Contract specifies the conditions under which participating Objects interact, exchange information, perform activities, or provide Capabilities. A Contract represents the rules governing an interaction rather than the interaction itself.

Purpose

This document defines Contract within the OCOM Specification.

A Contract establishes the governed agreement that defines expectations, responsibilities, obligations, and interaction rules between participating Objects.

Contracts provide a consistent mechanism for governing operational interactions across the OCOM ecosystem.

Business meaning

Contracts establish clear operational expectations between participating Objects.

They improve consistency, accountability, interoperability, and governance by making interaction rules explicit.
