How does the OSPO Network share best practices on open source under CADA?

Under the proposed Cloud and AI Development Act (CADA), the Network of Open Source Programme Offices (OSPO Network) serves as the central coordination hub

Summary Under the proposed Cloud and AI Development Act (CADA), the Network of Open Source Programme Offices (OSPO Network) serves as the central coordination hub for harmonizing open-source strategies across the EU public sector. As explicitly mandated in Article 44(3)(a), its primary mechanism for sharing knowledge is "facilitating the exchange of information, experience and best practices between Member States and the Commission." This structured dialogue targets common technical, legal, and organisational challenges—specifically licensing, security, maintenance, and procurement—to prevent fragmentation and promote the reuse of software. As proposed, this network would operate under Commission coordination, convening at least twice a year to ensure consistent implementation of open-source obligations across the Union.

Detail

The Cloud and AI Development Act (CADA), as proposed in COM(2026) 502 final, introduces a comprehensive framework to enhance transparency, security, and technological sovereignty through open source. A critical component of this framework is the establishment of the OSPO Network, designed to bridge the gap between local, regional, national, and Union-level entities. Unlike previous voluntary initiatives, this network would be a statutory body with a specific mandate to coordinate the implementation of open-source obligations.

The Legal Mandate for Exchange

The specific authority for the OSPO Network to act as a conduit for best practices is grounded in Article 44(3)(a) of the proposed Regulation. This provision explicitly tasks the network with:

"facilitating the exchange of information, experience and best practices between Member States and the Commission, in particular by discussing common technical, legal and organisational challenges, including those related to licensing, security, maintenance and procurement of open-source software;"

This legal framing is significant because it moves beyond passive information storage to active, structured dialogue. By enumerating "licensing, security, maintenance and procurement," the legislation identifies the four critical friction points where public sector bodies typically encounter barriers to open-source adoption. The network would serve as the formal mechanism to resolve these issues collectively rather than in isolation.

Context from Recital 84

The rationale for this structured exchange is further elaborated in Recital 84, which states that the OSPO Network is necessary to "facilitate the exchange of information and best practices." The recital emphasizes that the network should bring together relevant structures within Union entities and Member States to promote coordination. The ultimate goal, as described in the recital, is to ensure that the obligations to conduct open-source assessments and make software available for reuse (as outlined in Articles 41 and 42) are implemented "effectively and consistently across the Union."

Without such a network, the recital notes that software made available for reuse might be scattered across different repositories, "hampering searchability, discoverability and, ultimately, reuse." The OSPO Network would therefore act as the connective tissue ensuring that the EU Open Source Solutions Catalogue (Article 43) remains a functional, high-quality resource.

Key Areas of Best Practice Exchange

Based on the text of Article 44(3)(a) and the broader context of Chapter V (Open Source), the OSPO Network's best-practice sharing would likely focus on several high-impact areas:

Licensing Compliance and Strategy: Public sector bodies often lack specialized legal expertise to navigate the complexities of various open-source licenses (e.g., GPL, Apache, MIT). The OSPO Network would facilitate discussions on how to manage license compliance at scale, how to select appropriate licenses for publicly funded software, and how to handle license conflicts in complex dependency trees. This aligns with the need to address "common legal... challenges" cited in the Article.
Security and Maintenance: Security is a primary concern for CTOs and architects. The network would serve as a forum for sharing experiences on vulnerability management, patching strategies, and the long-term maintenance of open-source components. This includes discussing how to integrate open-source security standards into public procurement processes, addressing the "common technical... challenges" mentioned in the text.
Procurement and Contracting: Traditional public procurement frameworks are often ill-equipped for open-source software, which may be free but requires paid support or maintenance. The OSPO Network would help standardize procurement clauses that favor open-source solutions, ensuring that contracts address service-level agreements (SLAs), support obligations, and intellectual property rights effectively. This directly addresses the "procurement of open-source software" challenge highlighted in Article 44(3)(a).
Reuse and Interoperability: A major objective of CADA is to avoid duplication of effort. By sharing best practices on how to make software discoverable and reusable (via the EU Open Source Solutions Catalogue, as per Article 43), the OSPO Network would help public bodies identify existing solutions before building new ones. This promotes interoperability and reduces total cost of ownership, fulfilling the recital's goal of maximizing the value of public expenditure.

Governance and Coordination

The OSPO Network is not a regulatory enforcement body but a coordination mechanism. According to Article 44(4), the Commission would support and coordinate the network. This includes convening and chairing meetings "at least twice a year," which "may be organised online." This regular cadence ensures that the exchange of best practices is continuous and responsive to emerging technological and legal developments.

The network would be open to Open Source Programme Offices established by public sector bodies at local, regional, or national level in a Member State, as well as those established by Union entities (Article 44(2)). This inclusive structure ensures that best practices flow from both top-down (Union) and bottom-up (local) perspectives, preventing the fragmentation that currently hinders the EU's digital single market.

Impact on the EU Open Source Solutions Catalogue

While Article 44 focuses on the network, it works in tandem with Article 43, which establishes the EU Open Source Solutions Catalogue. The best practices shared via the OSPO Network would likely inform the criteria for listing software in this catalogue. For instance, the network might develop guidelines on what constitutes "high-quality" documentation or "secure" code, which would then be used to evaluate submissions to the catalogue. This synergy ensures that the catalogue is not just a repository, but a curated resource reflecting the collective expertise of the EU public sector.

What this means for you

For CTOs, architects, and SMEs operating in or supplying to the EU public sector, the OSPO Network represents a significant shift toward standardized open-source governance.

For Public Sector CTOs and Architects: You would have a direct channel to access proven strategies for managing open-source risks. Instead of developing internal policies from scratch, you could leverage the shared experiences of other Member States on licensing compliance and security maintenance. This would reduce the administrative burden and accelerate the adoption of open-source technologies. You should prepare to engage with your national OSPO to contribute to and benefit from this network.
For SMEs and Open-Source Providers: The standardization of procurement and licensing best practices through the OSPO Network could level the playing field. As public bodies adopt clearer, more open-source-friendly procurement clauses (discussed and refined within the network), it would become easier for SMEs to bid for contracts. Understanding the best practices emerging from this network could help you tailor your offerings to meet the evolving expectations of public sector buyers regarding security, maintenance, and license clarity.
For Legal and Compliance Teams: The focus on "common technical, legal and organisational challenges" means that legal interpretations of open-source licenses in a public sector context would likely become more harmonized. Staying informed about the outputs of the OSPO Network could help you anticipate shifts in regulatory expectations and compliance requirements.

Common misconceptions

Misconception 1: The OSPO Network is a regulatory enforcement body. The OSPO Network does not have enforcement powers. It is a coordination and exchange platform. Enforcement of open-source obligations remains with national competent authorities and the Commission, as outlined in other parts of CADA. The network's role is supportive and advisory, focused on "facilitating the exchange" rather than imposing sanctions.
Misconception 2: Only large Union entities will participate. Article 44(2) explicitly allows Open Source Programme Offices established by public sector bodies at local, regional, or national level in a Member State, as well as those by Union entities, to request membership. This ensures that best practices flow from both top-down (Union) and bottom-up (local) perspectives, preventing a disconnect between national strategies and local implementation.
Misconception 3: The network will mandate specific open-source licenses. The legislation does not mandate specific licenses. Instead, it facilitates the exchange of best practices on how to manage licensing. The choice of license remains with the public sector body, guided by objective criteria such as security, total cost, and functionality, as noted in Article 41. The network would help clarify the implications of these choices, not dictate them.
