 # Introduction
 
 ## Who should read this Rulebook?
 
-It is all about data. If you are using data-driven ecosystems or
-data-driven business models, you should build or join a data space --
-and therefore read this Rulebook. And if you are not yet, think about
-it!
-
-Data sharing is becoming a critical success factor for all businesses
-and organizations in all national and international economies. Data
-access and sharing also helps in meeting specific societal, policy, and
-legal objectives that are in the public interest. This Rulebook covers
-several types of data sharing: data sharing ecosystems, peer-to-peer
-data sharing, data marketplaces and data-driven platforms.
+This Rulebook is addressed to the broad community of actors who design, build, operate, regulate, or participate in data spaces. That includes private enterprises, public sector organisations, research institutions, standards bodies, service providers, and individuals who are responsible for data stewardship, compliance, or innovation. As data sharing assumes an ever more central role in economic activity and public policy, a clear understanding of the principles, requirements and governance models set out here is essential.
 
-The data space approach described in this Rulebook is for anybody
-interested in trusted and secure data access and sharing. It is relevant
-to businesses, organizations and individuals wanting to learn how their
-data rights can be handled in these data spaces.
+The Rulebook offers practical guidance for those working with diverse forms of data sharing — from peer-to-peer sharing and federated ecosystems to data marketplaces and platform-based services. It is especially useful for readers who seek to promote trustworthy, sovereign, and legally compliant data sharing; to manage business risk and contractual governance; and to implement technical architectures that preserve participant autonomy and agency.
 
 ## Goals and scope of the IDSA Rulebook
 
 ### Goals of the IDSA

-The International Data Spaces Association (IDSA) has defined a data sharing
-scheme (IDS), including a reference architecture, open source building
-blocks, and a certification process for creating and operating data
-spaces. IDS is based on commonly accepted data governance models
-facilitating secure sharing and easy linking of data within business
-ecosystems. The goal of IDSA is to make IDS a global standard for
-sovereign data sharing.
-
-The most important design principle for data spaces is to ensure data
-sovereignty for all data. This even enables the sharing of sensitive and
-most valuable data assets between selected participants. The IDS scheme
-guarantees data sovereignty for data owners who provide the shared data.
-This is the basis for offering smart services and for establishing
-innovative business processes.
-
-IDSA defines the technical foundation and a set of agreements for secure
-and trusted data spaces, where companies of all sizes and industries can
-manage their data assets. The association already counts over one
-hundred and thirty member organizations from twenty countries. The
-interplay of all these organizations as data space participants and
-service providers will deliver on the shared value proposition of
-generating business value from data.
-
-### The purpose and scope of the Rulebook
+The International Data Spaces Association (IDSA) aims to cultivate a vibrant practitioner community and to provide concrete guidance that enables the realisation of data spaces across a range of capabilities and organisational models.
 
-The IDSA Rulebook serves several purposes regarding the development and
-operation of data spaces. The aim is to describe clearly which rules are
-mandatory and which are optional guidelines. This governance framework
-includes functional, technical, operational, and legal dimensions:
+To that end, IDSA develops the Data Space Requirements (the Rulebook), the Reference Architecture Models (RAMs), and complementary implementation and operations guidance. IDSA also engages with international standardisation bodies and open-source initiatives to harmonise and share the knowledge contributed by its members, thereby supporting the global adoption and interoperability of data space technologies and business models.
+
+The central objectives for data spaces is the protection of the autonomy of participants, and to enable their agency over data sharing and use. This leads to the establishment of trustworthiness in data sharing. The IDSA Manifesto articulates the fundamental principles that underpin these objectives:
 
-- Guidelines for the functionality of common services are presented as
-    well as the definition, processes, and services of specific roles.
+<span style="color: red;">insert link and/or screenshot to the Manifesto here</span>
 
-- Guidelines how to implement or use a technical artefact of the IDSA.
+These principles provide the foundation for trusted data sharing and for the consequent development of data-driven services and business models.
 
-- Guidelines for the work and collaboration within data services.
+IDSA specifies foundational requirements and implementable reference architectures that enable organisations of all sizes and sectors to offer, discover, negotiate, and consume data-sharing arrangements for their digital assets.
 
-- Guidelines for the legal basis in compliance with the regulatory
-    environment to ensure trust and security.
+### The purpose and scope of the Rulebook
 
-This framework applies to all IDS-related roles and their interaction in
-the specific environment:
+The IDSA Rulebook supports the creation, operation, and growth of data spaces by distinguishing mandatory requirements from optional, value-adding practices. Its scope spans technical, commercial, and legal dimensions:
 
-1. The IDSA support organization is responsible for maintaining this
-Rulebook and supports its application. It enables the orchestration of
-processes and the realization of interfaces to other parties.
+- Common technical guidance, including functional requirements and the specification of value-adding services.
+- Recommendations for applying IDSA technical artefacts and for alignment with partner frameworks.
+- Operational guidance for collaboration, roles, and processes that enable data space ecosystems.
+- Perspectives on implementing and complying with international legal and regulatory obligations to facilitate trusted, cross-border data sharing.
 
-2. The essential service providers make these services available to the
-participants. They are the source of common agreements.
+The Rulebook describes how technical roles (for example, Participant and Data Space Governance Authority — DSGA) relate to economic and legal responsibilities, and how these roles may map to obligations under instruments such as the EU Data Governance Act and the EU Data Act. <span style="color: red;">insert link to the acts</span>
 
-3. All IDS users are getting guidance on how to proceed in realizing
-use cases based on a trustworthy infrastructure and governance.

+### Eclipse Foundation
 
-Four key European organizations (IDSA, Gaia-X, FIWARE, BDVA/DAIRO) have
-formed an alliance creating one voice and a common framework to make
-data spaces happen. Together, the DSBA represents 1,000+ leading
-industry players, associations, research organizations, innovators, and
-policymakers worldwide. With its combined cross-industry expertise,
-resources, and know-how, the DSBA drives awareness and technology
-adoption, shapes standards and enables integration of data spaces across
-industries.
