Abstract · 摘要

Against the backdrop of deep integration between the digital economy and global trade, cross-border product circulation is evolving from physical flow to trusted flow. Digital Product Passports (DPPs), as an emerging digital trust infrastructure, have achieved significant progress in the environmental data domain for industrial products, yet notable gaps remain in their coverage of cultural products, specialty agricultural goods, geographical indication products, and other categories.

This document systematically presents the overall architecture, core specifications, governance mechanisms, and implementation roadmap of the DPP-CQ Digital Product Passport for Cultural & Quality Goods standards framework. Built upon mature technologies such as W3C DIDs, Verifiable Credentials (VCs), and Zero-Knowledge Proofs (ZKPs), this framework focuses on establishing digital trust in the cultural value and quality dimensions, addressing the inclusivity gap in existing DPP standards ecosystems.

The core standard, ICO Std 2001 (DPP-CQ), is a digital passport specification for cultural and quality products. It supports dual carriers of QR codes and NFC, provides a three-tier verification mechanism, and protects sensitive craftsmanship and commercial data through zero-knowledge proofs. The standards framework employs a multi-stakeholder governance model to ensure openness, neutrality, and inclusivity.

This document is issued as a Public Review Draft. We sincerely invite governments, enterprises, academic institutions, and non-governmental organizations worldwide to participate in building a more inclusive global digital trust ecosystem.

1. Introduction · 前言

In an era of deep integration between the digital economy and global trade, cross-border product circulation is transitioning from physical flow to trusted flow. However, significant inclusivity gaps exist in the current global digital product verification ecosystem:

  • Existing Digital Product Passport (DPP) standards primarily focus on environmental and circular economy data for industrial products, and do not adequately cover categories such as cultural products, specialty agricultural goods, and geographical indication products.
  • A vast number of products with unique cultural value and quality advantages lack digital trust-transmission tools, making it difficult for them to fully realize their value in global markets. According to a joint OECD/EUIPO study, global trade in counterfeit goods reached USD 467 billion in 2021, accounting for 2.3% of global imports. Among these, geographical indication products and specialty cultural products, with their high recognizability and premium pricing potential, have become prime targets for counterfeiting. Specialty products from developing countries are severely undervalued due to lack of trust.
  • Developing economies face multiple challenges in digital trust infrastructure development, including technological, standardization, and capacity gaps. The UN Global Digital Compact (GDC) explicitly calls for increased support for digital capacity building in developing countries to ensure that digital technologies benefit all people.

The International Communication Organization (ICO), as a multi-stakeholder international cooperation platform, is committed to advancing Global Digital Inclusion and Cross-Cultural Digital Trust. This document presents the overall architecture, core standards, governance mechanisms, and implementation roadmap of the ICO standards framework, and invites global stakeholders to join us in building a more inclusive global digital trust ecosystem.


2. Mission & Vision · 使命与愿景

2.1 Mission

To empower the digital preservation and value transmission of global cultural and quality assets through open standards.

以开放标准赋能全球文化与品质资产的数字化保护与价值传递。

2.2 Vision

To build a globally applicable, technology-neutral, and culturally inclusive digital trust standards framework, ensuring that every product carrying cultural value and quality commitment possesses a verifiable, traceable, and mutually recognizable digital identity. By 2030, achieve 100,000+ cultural and quality products with globally mutually recognizable digital identities, driving global trade from price competition to value competition.

2.3 Core Principles

Principle Description Practical Manifestation
Open Standards are open to all stakeholders, regardless of country, region, or ownership structure Free adoption with no membership fee barriers
Neutral Technology-agnostic architecture, not tied to any specific vendor or technology stack Supports multiple blockchain and cloud platforms
Inclusive Fully considers the needs of different cultural backgrounds and development stages Supports lightweight implementations for low-resource environments
Interoperable Based on international technical standards, ensuring connectivity with existing and future systems Compatible with W3C, ISO, GS1, UNECE, and other standards
Trustworthy Verifiable data, traceable processes, and adjudicatable disputes Three-tier verification + Root Resolver Network + ZKP privacy protection
Privacy by Design Privacy protection embedded in architectural design; data minimization Zero-Knowledge Proofs + Selective Disclosure

3. Background & Rationale · 背景与必要性

3.1 The Trust Deficit in Global Trade

In current cross-border global trade, categories such as specialty agricultural goods, cultural products, and handicrafts face pervasive trust challenges: consumers struggle to verify the true origin, quality grade, and cultural background of products; purchasers lack efficient and reliable supply chain traceability tools; authentication of geographical indication products is costly; and cultural value and craft heritage cannot be effectively transmitted through traditional channels.

A direct consequence of this trust deficit is the “bad money drives out good money” effect — genuinely superior products and producers who uphold traditional craftsmanship are unable to obtain returns commensurate with their value in the global market.

3.2 Coverage Gaps in Existing Standards

Existing DPP standards are primarily led by advanced economies, focusing on environmental footprints and circular economy data for industrial products, compliance-driven mandatory information disclosure, and serving the market access requirements of developed economies. Significant standard gaps remain in the following areas:

Gap Area Current State ICO Positioning
Digital confirmation of cultural product rights No unified cultural value data standard Establish cultural data models and verification specifications
Cross-border mutual recognition of Geographical Indications WIPO has legal framework but no technical standards Develop GI digital mutual recognition technical specifications
Quality grading for specialty agricultural goods Individual national standards, no global unified digital framework Establish cross-cultural quality assessment methodology
Digital capacity in developing economies High technical barriers, high costs, low participation Provide lightweight, low-threshold solutions

3.3 Interoperability with Existing Standards

ICO standards adopt a strategy of “compatibility first, supplementation and extension”:

  • W3C DID/VC: Used as the underlying identity and credential technology foundation, fully compatible
  • GS1 Identification System: Supports mapping and interoperability with GS1 product coding systems
  • UNECE Global DPP Interoperability Initiative: Participates in the global DPP interoperability framework led by the United Nations Economic Commission for Europe
  • EU DPP/ESPR: Designs data mapping pathways for cross-system information sharing
  • ISO-related standards: Compatible with standards such as ISO 22000 (food safety) and ISO 26000 (social responsibility)

3.4 Technology Maturity Window

Technologies such as W3C DIDs (Decentralized Identifiers), Verifiable Credentials, blockchain-based evidence anchoring, and Zero-Knowledge Proofs (ZKPs) have entered mature application phases, providing the technical foundation for building a globally applicable open standard for the cultural and quality dimensions.

Meanwhile, international documents and data such as UNESCO’s Operational Directives for the Implementation of the Convention for the Safeguarding of the Intangible Cultural Heritage (2016/2018 edition) and WIPO’s World Intellectual Property Indicators 2024 all indicate the urgency and necessity of leveraging digital technology to protect cultural assets and geographical indications. The timing is opportune for establishing open standards oriented toward the cultural and quality dimensions.

  • Selective Disclosure: Data holders may choose the scope of disclosure based on the verification scenario

Applicable Categories: Geographical indication agricultural products (tea, grains & oils, fruits, medicinal herbs, spices), Intangible Cultural Heritage products (ceramics, embroidery, lacquerware, woodwork), haute couture and cultural attire, premium food and beverages, handicrafts and cultural creative products.

5.2 ICO Std 1001: Global Information Integrity & Data Provenance

Defines the credibility assessment framework and provenance methodology for digital content and data assets, with particular emphasis on provenance identification specifications for AI-generated content. Covers data integrity verification, provenance chain construction methods, credibility grading assessment, timestamps, and evidence anchoring interfaces.

5.3 ICO Std 3001: Global Digital Credibility Certification (GDCC)

A digital credibility assessment and certification standard for institutions (enterprises, media, NGOs, etc.), constructing an assessment system across multiple dimensions including information transparency, data credibility, governance compliance, and cultural responsibility, with support for cross-cultural scenario adaptation.


6. Governance · 治理架构

6.1 Multi-Stakeholder Governance Model

The ICO standards framework employs a multi-stakeholder governance model to ensure the openness, representativeness, and credibility of standards. Important decisions follow a consensus-first principle; where consensus cannot be reached, decisions are adopted by a two-thirds majority.

Governance design references best practices from international standards bodies such as W3C and IETF, ensuring:

  • Balanced representation of economies at different development stages
  • Diverse participation from government, industry, academia, and civil society
  • Effective separation of technical decision-making from commercial interests

6.2 Governance Structure

General Assembly (supreme decision-making body): Convened annually to deliberate on strategic direction, budget, and Council elections.

Standards Council (decision-making body): Responsible for strategic decisions, standard approval, budget approval, and final dispute adjudication. Seats are allocated by category: Government Representatives 25% / Industry 25% / Academia 20% / Civil Society 20% / Technical Secretariat 10% (non-voting).

Specialized Committees:

  • Technical Committee: Responsible for standard technical review and technical roadmap planning
  • Strategy Committee: Responsible for strategic planning and external cooperation
  • Compliance & Dispute Committee: Responsible for compliance review and dispute adjudication

Standards Working Groups:

  • WG-DPP: Digital Product Passport Working Group
  • WG-GI: Geographical Indication Mutual Recognition Working Group
  • WG-DID: Decentralized Identifiers and Credentials Working Group
  • WG-GDCC: Institutional Credibility Assessment Working Group
  • WG-Governance: Governance Rules Working Group

6.3 Technical Secretariat

The Technical Secretariat is the neutral executive body of the standards framework, undertaken by a designated entity authorized by the Standards Council. Its core responsibilities:

  • Maintain reference implementations and open-source code repositories for the standards
  • Provide technical support and conformance testing platforms
  • Operate the root resolution infrastructure and trusted registries
  • Support the technical work of working groups
  • Organize technical training and developer community building

Key Principle: The Technical Secretariat does not participate in standard voting, ensuring the separation of technical execution from standards development.

6.4 Infrastructure and Root Resolution Mechanism

To ensure high security and continuous availability of data resolution in global cross-border circulation, the ICO Council authorizes the Technical Secretariat to build and operate:

  • ICO Root Resolver Network: A globally distributed DID resolution infrastructure providing highly available, low-latency identifier resolution and credential status query services
  • Tianji Credibility Registry (TCR): A unified credential hash registration and anchoring database

Operating Mechanism: When any third-party certification body or service provider issues Digital Product Passports under ICO Std 2001/2003, the credential hash fingerprints and identifiers (DIDs) generated must be registered and consensus-anchored at the root nodes, ensuring traceability and judicial-grade authenticity verification across networks and geographical regions worldwide.

Security Assurance:

  • Multi-region redundant deployment with 99.99% availability target
  • At least one independent third-party security audit per year, with audit reports made public
  • Major technical upgrades require review by the Technical Committee and approval by the Standards Council

7. Technical Approach · 技术路线

7.1 Technology Selection Principles

  • International Standards First: Prioritize adoption of published international standards (W3C, IETF, ISO)
  • Open Source & Open: Core technology stack based on open-source licenses
  • Extensible Architecture: Modular design supporting future standard extensions
  • Privacy by Design: Data minimization principle, supporting selective disclosure and Zero-Knowledge Proofs

7.2 Core Technology Stack

Layer Technical Standard Reference / Compatible Specification
Decentralized Identifiers W3C DID Core 1.0 W3C Recommendation (Jul 2022)
Verifiable Credentials W3C Verifiable Credentials Data Model v2.0 W3C Recommendation
Data Semantics JSON-LD 1.1 W3C Recommendation / IETF BCP 19
Cryptographic Signatures BBS+ Signatures / Ed25519 IETF RFC / RFC 8032
Data Anchoring Cryptographic Hash Anchoring Blockchain-agnostic, multi-chain support
Physical Verification NFC Forum Type 2/4 · QR Code ISO 18004 NFC Forum / ISO Standard
Interface Specification RESTful API / OpenAPI 3.0 OpenAPI Initiative

7.3 Multi-Chain and Multi-Cloud Architecture

ICO standards are not bound to any specific blockchain or cloud platform. Through a unified hash anchoring abstraction layer, multiple underlying storage solutions are supported (public chains, consortium chains, distributed hash tables, trusted cloud storage, etc.). Different jurisdictions may select anchoring solutions compliant with local regulations while maintaining cross-chain verification consistency.

7.4 Open Source Strategy

Component Open Source License Description
Standards documentation CC BY 4.0 Free to use, reproduce, and adapt; attribution required
Base protocol reference implementations Apache 2.0 Fully open, business-friendly
SDKs and development tools Apache 2.0 Multi-language SDKs, encouraging ecosystem participation
Contribution mechanism CLA Contributor License Agreement ensuring clear intellectual property rights

7.5 Intellectual Property Policy

The ICO standards framework adopts an intellectual property policy of “openness first, reasonable protection”:

Standard-Essential Patent (SEP) Policy:

  • Encourages patent holders to license their essential patents on FRAND (Fair, Reasonable, and Non-Discriminatory) terms
  • Core standards (DIDs, credential formats, and other base layers) prioritize open-source technology solutions free of patent encumbrances
  • Patent searches and disclosures are conducted prior to standard publication to minimize potential patent risks
  • An Intellectual Property Working Group is established to oversee patent policy development and dispute resolution

Trademark and Logo Policy:

  • “ICO Certified” mark, “DPP-CQ” mark, and others are registered trademarks of ICO
  • Certified products and services may use official marks subject to compliance requirements
  • Logo usage specifications and supervision mechanisms are established to prevent abuse and misleading
  • Logo usage by regional nodes and partners requires authorization and review

Copyright Policy:

  • Copyright in standard texts is held by ICO and made available under the CC BY 4.0 license
  • Copyright in reference implementations and tool code is held by contributors and open-sourced under the Apache 2.0 license
  • Third-party derivative works must comply with the corresponding open-source licenses and indicate source

7.6 Standards Version Management

Version Numbering Scheme: Uses the format “major.minor.patch” (e.g., v1.2.3)

  • Major version: Incompatible architectural changes
  • Minor version: Backward-compatible functional additions
  • Patch version: Backward-compatible bug fixes

Backward Compatibility Commitments:

  • Minor version updates maintain backward compatibility of data formats and interfaces
  • Major version updates provide at least 12 months of transition period and migration tools
  • The validity of issued credentials is not affected by standard version updates

Standards Lifecycle:

  • Working Draft (WD) → Committee Draft (CD) → Public Review Draft (PR) → International Standard (IS)
  • International standards are reviewed every 5 years to ensure continued validity
  • Obsolete standards initiate revocation procedures with advance notice to all adopters

8.1 Data Sovereignty and Cross-Border Compliance Architecture

ICO standards employ an architectural design of “data localization, hash cross-border”, fundamentally reducing cross-border data compliance risks:

  • Raw data stored locally: Detailed product quality, craftsmanship, and supply chain data are stored locally by the issuer or certification body, with no mandatory cross-border transmission
  • Hash fingerprint anchoring: Only hash fingerprints of data (one-way irreversible) are registered and anchored at root nodes; hashes themselves contain no identifiable original information
  • Zero-Knowledge Proof verification: Sensitive data is verified via ZKP technology; verifiers receive only compliance conclusions without access to raw data

This architecture is compatible with China’s Data Security Law and Personal Information Protection Law, the EU’s General Data Protection Regulation (GDPR), and the data sovereignty principles of most countries.

8.2 Compliance Adaptation by Major Jurisdictions

Jurisdiction Core Compliance Requirements ICO Standard Adaptation
China Data classification and grading, security assessment for outbound transfer of important data, critical information infrastructure protection Localized data storage, hash cross-border, independent deployment of domestic root nodes
European Union GDPR data protection, Digital Markets Act (DMA), ESPR environmental disclosure ZKP selective disclosure, data minimization, data mapping with EU DPP
Southeast Asia Significant variation in national data protection laws, differing localization requirements Flexible regional node deployment, configurable data storage strategies
Global South Relatively weak data regulations, insufficient digital capacity Lightweight solutions, capacity building support, technology transfer

ICO standards are themselves technical and industry standards, without legal force (consistent with the nature of international standards such as those from ISO). However, their design fully considers judicial evidence requirements:

  • Hash integrity proof: Cryptography-based data integrity verification can serve as electronic evidence in most jurisdictions
  • Trusted timestamps: Integration with authoritative timestamp services meets the temporal certainty requirements for electronic evidence
  • Complete evidence chain: Issuance chains, change records, and revocation logs constitute a complete evidence chain
  • Third-party audits: Root nodes and core services undergo regular independent third-party audits to enhance evidentiary credibility

Specific legal effect varies by jurisdiction. ICO encourages regional nodes to collaborate with local legal institutions to promote recognition of the evidentiary weight of DPP-CQ credentials in their respective jurisdictions.

8.4 Dispute Resolution Mechanism

Referencing UNCITRAL (United Nations Commission on International Trade Law) arbitration rules and international commercial arbitration practices, ICO establishes a three-tier dispute resolution mechanism:

  1. Self-Help Mediation: Parties negotiate independently through platform tools
  2. Expert Review: A review panel composed of industry and technical experts issues a ruling
  3. Arbitration (Final): Submission to international commercial arbitration, with arbitral awards enforceable globally under the New York Convention

12. Conclusion · 结语

In the digital age, trust is the most precious public good.

From the Industrial Revolution to the Information Revolution, every leap in human society has been accompanied by iterations in trust mechanisms. Today, as digital technology reshapes global trade and cultural exchange at an unprecedented pace, we need a more inclusive and pluralistic digital trust infrastructure — one that not only serves efficiency optimization for industrial products but also safeguards the diversity of human culture, ensuring that the unique value of every civilization can be seen, recognized, and respected in the digital world.

The ICO standards framework is committed to providing open, neutral, and inclusive digital trust infrastructure for global cultural and quality assets. We are not building a closed standards system; rather, we are contributing to the global digital trust edifice — using W3C’s technical language to write chapters of cultural value; using multi-stakeholder governance wisdom to build cross-cultural bridges of trust.

We look forward to a future where every product carrying human wisdom and cultural value possesses a trustworthy digital identity — making global trade fairer, cultural heritage more vibrant, and the digital economy more human-centered.

We invite stakeholders worldwide to submit revision proposals by August 20, 2026 (Accelerated Procedure · 45-day review period), and to join us in building a more inclusive global digital trust future.

Annex E (Informative): Frequently Asked Questions

附录E(资料性)常见问题

Q1: What is ICO? What qualifications does it have to develop international standards?

ICO (International Communication Organization) is a multi-stakeholder international cooperation platform dedicated to advancing global digital inclusion and cross-cultural digital trust.

The ICO standards framework employs an open community-driven development model, following best practices in international standard-setting (openness, transparency, consensus, balanced representation). The vitality of standards lies in adoption and ecosystem, not administrative mandate — the core Internet protocols (TCP/IP, HTTP, etc.) were not promulgated by governments or official bodies, but became de facto standards through joint advancement by open-source communities and standards organizations and widespread market adoption. ICO is committed to becoming the de facto standard-setter in the field of cultural and quality digital trust.

Q2: What is the relationship between ICO standards and the EU DPP? Will they conflict?

A complementary relationship, not a competitive one.

The EU DPP (under the ESPR framework) focuses primarily on environmental and circular economy data for industrial products — a “green dimension” Digital Product Passport. ICO DPP-CQ focuses on the cultural value and quality dimensions of cultural products and specialty agricultural goods — a “cultural dimension” Digital Product Passport. The two cover different product categories and data dimensions; they are complementary rather than substitutive.

At the technical level, DPP-CQ is fully compatible with W3C DID/VC standards, sharing the same technical foundation as the EU DPP, enabling data interoperability. We welcome standard coordination and mutual recognition dialogue with relevant EU institutions.

Q3: Why is a Root Resolver Network needed? Will it create a monopoly?

The core function of the Root Resolver Network is to ensure consistency of DID resolution and queryability of credential status in global cross-border circulation. This is analogous to the root servers of the Domain Name System (DNS) — not for the purpose of monopolization, but for the purpose of interoperability.

The design of the root resolution mechanism follows the following principles:

  • Technology-neutral: Root nodes only provide resolution and anchoring services; they do not participate in standard-setting and do not engage in commercial competition;
  • Governance constraints: Root node operation is overseen by the Technical Committee and authorized by the Standards Council; major changes require approval through governance processes;
  • Gradual decentralization: The long-term goal is to establish a distributed root node network with multiple regions and multiple operators, avoiding single-point dependencies;
  • Open source and open: The reference implementation of root nodes is fully open-source, and any institution may deploy a compatible node.

Q4: How are data security and privacy ensured? Will data exit issues arise?

ICO standards employ an architectural design of “data localization, hash cross-border”:

  • Raw data stored locally: Detailed product quality, craftsmanship, and supply chain data are stored locally by the issuer or certification body, with no mandatory cross-border transmission;
  • Hash fingerprint anchoring: Only hash fingerprints of data (one-way irreversible) are registered and anchored at root nodes; hashes themselves contain no identifiable original information;
  • Zero-Knowledge Proofs: Sensitive data is verified via ZKP technology; verifiers receive only compliance conclusions without access to raw data;
  • Compliance adaptation: Regional nodes may conduct localized deployment and compliance adjustments in accordance with local data regulations.

This architecture fundamentally reduces the risk of cross-border flow of raw data and complies with regulatory requirements for data sovereignty and data security in all countries.

Q5: What is the relationship between the Tianji system and ICO?

The Tianji system (天机体系) is one of the institutions undertaking the role of Technical Secretariat for the ICO standards framework, responsible for reference implementation of standards, root node operation and maintenance, and technical support.

This arrangement is analogous to the relationship between W3C and host institutions such as MIT/ERCIM — standards are developed jointly by the community, and the Technical Secretariat is responsible for execution and implementation. The Tianji system, as a technical service provider, does not participate in standard voting, ensuring separation of standard-setting from technical execution.

Q6: Is there a fee to adopt ICO standards?

The standards themselves are completely free.

  • Standards documentation: Free to download and use (CC BY 4.0 / Apache 2.0)
  • Reference implementations: Open-source and free, freely modifiable and commercially usable
  • Basic verification: Basic functions such as scan-to-verify are freely available

Value-added services (such as custom development, advanced certification, technical support, etc.) may be provided by service providers in the ecosystem; ICO itself does not directly operate commercial services.

Q7: What is the relationship with GS1 and ISO? Is this a separate stovepipe effort?

No, it is not a separate stovepipe effort. ICO standards are built upon existing international standards such as W3C, ISO, and GS1, serving as a supplement and extension of the existing standards ecosystem in the cultural and quality dimensions.

W3C DID is the “technical standard for ID cards” (telling us how to make the card), ISO/GS1 is the “industry coding specification” (telling us how to number things), and ICO DPP-CQ is the “content specification for cultural product passports” (telling us what content goes in the passport and how to verify cultural value). We use W3C’s card technology, are compatible with GS1’s coding system, and focus on content standards for the vertical domain of culture and quality.

We actively seek cooperation and mutual recognition with standards organizations such as ISO, W3C, and GS1.

Q8: Can small and medium-sized producers afford it? Will it increase their burden?

This is precisely one of the core concerns of ICO standards.

Our design goal is to enable small and medium-sized producers and ICH transmitters to “afford and benefit from” the system:

  • Low-cost solutions: Support low-cost verification methods such as QR codes, with startup costs as low as a few cents per item;
  • Lightweight onboarding: SaaS-based certification platforms are provided, requiring no technical team — usable upon registration;
  • Volume discounts: Discounts or waivers for small and medium-sized producers and ICH transmitters;
  • Capacity building: Training and technical support provided through regional nodes and partners.

We believe that the “premium for quality” effect brought by digital passports will far exceed their usage cost — helping good products command good prices is the most direct value empowerment for producers.

Q9: What about the legality and evidentiary effect of the standards?

ICO standards are themselves a set of technical and industry standards, without legal force (consistent with the nature of international standards such as those from ISO). However, their design fully considers judicial evidence requirements:

  • Hash anchoring: Cryptography-based data integrity proof can serve as electronic evidence in most jurisdictions;
  • Trusted timestamps: Integration with authoritative timestamp services meets the temporal certainty requirements for electronic evidence;
  • Complete evidence chain: Issuance chains, change records, and revocation logs constitute a complete evidence chain;
  • Third-party audits: Root nodes and core services undergo regular independent third-party audits to enhance evidentiary credibility.

Specific legal effect varies by jurisdiction. ICO encourages regional nodes to collaborate with local legal institutions to promote recognition of the evidentiary weight of DPP-CQ credentials in their respective jurisdictions.

Q10: How is the neutrality of the standards ensured? How can we be certain no single party dominates?

The multi-stakeholder governance mechanism is the institutional guarantee for standard neutrality:

  • Balanced representation: Council seats are allocated by category (government 25%, industry 25%, academia 20%, civil society 20%, Technical Secretariat 10% non-voting), so no single group can dominate decision-making;
  • Consensus-first: Important decisions prioritize seeking consensus rather than simple majority voting;
  • Separation of technology and standards: The Technical Secretariat does not participate in standard voting, separating execution from decision-making;
  • Transparency and openness: Governance processes are open and transparent, subject to community oversight;
  • Open participation: Any institution may apply to join, regardless of nationality, size, or ownership structure.
