Chapter 1 Introduction

1.1 Purpose

"Open Data Spaces Introductory Guidebook for Developers (this document)" is intended for engineers who are in a position to adopt, implement, or provide services refering to ODS. Its purpose is to provide an initial guide for understanding the overall technical landscape and fundamentals, and for beginning design, implementation, and operations.

Open Data Spaces (ODS)" is an open and scalable foundation for distributed data, built on organizational and national diversity by design. Its adoption requires not merely system construction, but an approach that encompasses technology, compliance, and business considerations. For this reason, enterprises must make decisions — prior to asking "which technology to use" — about what to implement, how much to take on internally, and where to delegate to others. This document is not a technical manual or procedural guide explaining individual specifications or implementation steps; its primary focus is on providing the conceptual understanding and evaluation perspectives needed for making implementation decisions.

Accordingly, this document aims to help enterprises that are adopting or providing ODS-based services understand the overall picture of ODS from their perspective, and to serve as an "entry point for stepping into design and implementation" toward the adoption of Open Dataspaces technologies.

1.2 Intended Readers

The engineers referred to in this document encompass a broad range of personas involved in the adoption, implementation, and planning of technologies related to data management and AI:

  • Architects and technical leads at enterprises responsible for ODS adoption and implementation

  • Architects and technical leads at software companies and their technical departments seeking to implement distributed data management services leveraging ODS

  • Developers, academics, students, and others who wish to explore ODS technology
