The project dates 2.0 to April 2019 and says it is functionally identical to OpenChain 2.1 and ISO/IEC 5230:2020. ISO lists the 2020 edition as current and says it was reviewed and confirmed in 2026. OpenChain’s version and conformance information and ISO’s record clarify why 2.0 is best understood as the historical text of the current standard, not a separate current ISO edition.
What is OpenChain Specification 2.0?
OpenChain Specification 2.0 sets requirements for a quality open-source license-compliance program. Its aim is to build trust between organizations exchanging software that includes open-source components. ISO’s abstract describes ISO/IEC 5230:2020 as specifying the key requirements of such a program to provide a benchmark for that trust. ISO/IEC 5230:2020 record

The distinction matters: the organization’s program is assessed for conformance. A software package may benefit from being prepared under that program, but the package itself is not “OpenChain conformant.” When evaluating a supplier, ask whether the supplied software was prepared under a conformant program.

The specification sets out areas a compliance program must cover while leaving organizations room to choose processes that fit their operations. Its requirements span the foundations of the program, the work people perform, the review of software, and the way compliance information is delivered and maintained. OpenChain Specification 2.1 text
#1 Best Overall
- Program foundation: policy, competence, awareness, scope, and understanding license obligations.
- Relevant tasks: defining and supporting the work needed to operate the program.
- Review and approval: reviewing open-source content, including a bill of materials and license compliance.
- Compliance artifacts: creating and delivering the materials required for software distribution.
- Community engagement: understanding how the organization interacts with open-source communities, including through contributions.
- Adherence: maintaining the program and the conformance claim over time.
What artifacts might a program deliver?
The exact materials depend on the licenses that govern the software being supplied. Possible outputs include:
- Attribution and copyright notices
- Source code, build scripts, and installation scripts
- Copies of applicable licenses
- Notices describing modifications
- Written offers where applicable
- An open-source component bill of materials
- SPDX documents
This is an illustrative, not exhaustive, list; a program needs to determine the obligations that apply to its software rather than assume every package needs the same set of artifacts. OpenChain FAQ
How does an organization establish conformance?
A program is conformant only if it satisfies all applicable requirements. The organization defines the program’s scope, which may be limited to one product or part of the business or extend more broadly. Scope can shape the scale of implementation, but it does not waive requirements within the chosen program scope. OpenChain license-compliance page

The project identifies two routes for demonstrating conformance:
Rank #3
- Used Book in Good Condition
| Route | What it involves | What to consider |
|---|---|---|
| Self-certification | The organization evaluates its program against the requirements and makes a conformance claim. | Requires internal ownership and careful review. The official pages consulted do not publish a comparative cost or time estimate. |
| Partner-assisted assessment or third-party certification | The organization works with an official partner for independent assessment or certification. | Provides external support or assessment. The official pages consulted do not establish that an external audit is mandatory for every organization or publish comparative costs. |
An organization might begin with a defined product area and expand its scope later, provided its conformance claim accurately describes the program being assessed. OpenChain also publishes self-certification and implementation resources; the specification itself is not an implementation manual. OpenChain conformance information
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What the specification does not do
OpenChain defines program requirements, not a single prescribed implementation method. The project says the document focuses on the “what” and “why” rather than the “how” and “when.” Organizations can therefore select processes suitable for their size, markets, products, and chosen scope; practical playbooks and reference material are separate resources. Specification text
Conformance is also not a legal opinion or a guarantee that every license obligation has been met. The project calls for designated legal expertise and a process that gives appropriate attention to analyzing and fulfilling license obligations. The specification does not replace legal advice or interpret a particular license for an organization. OpenChain FAQ

Quick Recap
Why do organizations use OpenChain?
A shared benchmark can help organizations that exchange software communicate how open-source license compliance is managed. It gives suppliers and customers a common program-level reference without requiring every organization to use identical internal workflows. The OpenChain FAQ reports that 20% of German companies with more than 2,000 employees were using OpenChain ISO/IEC 5230, citing a 2021 Bitkom survey sponsored by PwC. That figure is the FAQ’s report of the survey result, not an independently verified measurement here. OpenChain FAQ
