Introduction

Purpose and Background

This protocol specification document (Open Dataspaces Protocol: ODP) aims to provide an abstract specification of interoperable communication procedures (Protocol) that references the Open Data Spaces Reference Architecture Model (ODS-RAM) and aligns with its design principles. It translates the functions of each layer and perspective described in ODS-RAM into an abstract protocol specification, providing implementers with technical development guidelines grounded in its design philosophy. Furthermore, it seeks to deliver an abstract specification with extensibility and generality that, while presenting reference implementation examples, offers implementers flexibility in their choice of technology stack.

Status of the Protocol Specification

This protocol specification is established as the official normative protocol specification within the ODS ecosystem and will be continuously updated in accordance with revisions to the ODS-RAM and related documents.
