ECL-2.0 is Apache-2.0 with a narrower patent grant aimed at universities. Notice and NOTICE-file rules still apply.
On this page
What it does
The Educational Community License 2.0 is Apache-2.0 with the patent grant limited so a university's entire patent portfolio is not licensed by one contributor dropping code in. Keep copyright, license, and NOTICE. State changes. You will meet it on Sakai, Kuali and other higher-ed software. Do not assume the patent grant is as wide as Apache-2.0.
Pros
- Easy to drop into a closed, paid product. Procurement has seen this family many times.
- No copyleft on your own files. You keep your source private.
Cons
- The notice duty is easy to miss in a desktop, mobile, or container build. A web page is not a substitute for notices inside the artifact.
- Transitive copies in the lockfile count. Listing only direct dependencies leaves notices out.
What it allows and requires
Choose a category to see the full grant in one scannable list. Permissions show what the license allows, limits show what it withholds, and obligations show the conditions your release process must satisfy.
Permissions
Commercial use
You may ship the code inside a paid product. The license does not restrict commercial use.
Modify
You may change the code, including keeping those changes private, unless a later obligation says otherwise.
Distribute
You may give copies to others. Distribution is what usually turns notice and source duties into real work.
Sublicense
You may include the code under your own product terms, so long as you still meet this license's conditions.
Private use
Use inside your company, including internal forks, does not by itself trigger distribution duties.
Patent use
The license includes an express patent grant from contributors for the licensed work.
Limits
Hold liable
The authors disclaim warranty. Recipients cannot hold them liable for damages arising from the software, except where law forbids that disclaimer.
Use trademark
The license is not a trademark license. Names, logos and product marks stay with their owners unless a separate grant says otherwise.
Obligations
Include copyright
Keep the copyright line with every copy or substantial portion you distribute.
Include license
Keep the license text with every copy or substantial portion you distribute. A web page is not a substitute for notices inside a shipped artifact.
Include notice
If a NOTICE file travelled with the work, reproduce the attribution notices from it in the form the license describes.
State changes
Mark changed files so they are not misrepresented as the original.
What ECL-2.0 requires when you ship
When a copy that includes ECL-2.0 code leaves your company, the grant is broad and the paperwork is easy to miss. Distribution here means an installer, a mobile binary, a container image, or an SDK another team embeds. Work this list against the artifact you actually hand over, not against a README. A hosted service that never gives out a copy still belongs on the record, but the notice duty does not fire until a copy exists.
You meet the notice condition when each ECL-2.0 component's copyright line and license text appear in the material the recipient actually gets.
You are done for a hosted service that never hands out a copy. Running the software for users over a network does not, by itself, trigger a notice duty.
You are covered for a desktop, mobile or on-premise build when the notices sit inside the artifact. An about screen or a bundled licenses file both work.
The duties named in ECL-2.0
The license text itself is short. These are the named conditions. They follow the code, including files you vendor into your own repository and transitive packages in the lockfile.
Include copyright
Keep the copyright line with every copy or substantial portion you distribute.
Include license
Keep the license text with every copy or substantial portion you distribute. A web page is not a substitute for notices inside a shipped artifact.
Include notice
If a NOTICE file travelled with the work, reproduce the attribution notices from it in the form the license describes.
State changes
Mark changed files so they are not misrepresented as the original.
Things to be aware of
- Reading ECL-2.0 as no obligations at all and shipping a binary with no notices in it. Put the notices in the artifact you hand over.
- Deleting the license header when you copy one or two files into your own repository. The condition follows the code, not the package it came in.
What the Educational Community License v2.0 does not do
Search results often flatten Educational Community License v2.0 into a slogan. These are the usual misreads. ECL-2.0 is a grant with conditions, not a permission to skip the paperwork below.
- ECL-2.0 does not mean no obligations. The copyright line and the license text still have to travel with copies you distribute.
- ECL-2.0 does not force you to open your own source. There is no copyleft here unless a later clause in this text says otherwise.
How ECL-2.0 differs from nearby licenses
These licenses are often confused with ECL-2.0, but their release duties differ. Each row summarizes what the license requires when you ship. Open the linked page for the full checklist.
- ECL-2.0
- ECL-2.0 is Apache-2.0 with a narrower patent grant aimed at universities. Notice and NOTICE-file rules still apply.
- Apache-2.0
- Permissive like MIT, plus an express patent grant. The catch is the NOTICE file: it has to travel inside the binaries you ship.
- AFL-3.0
- AFL-3.0 is a permissive academic grant with an express patent license and a source-attribution duty. OSI-approved. Closest cousin is Apache-2.0, not MIT.
Common questions about Educational Community License v2.0
Answers to common questions about what Educational Community License v2.0 requires, when its duties apply, and what evidence belongs with a release.
What is the Educational Community License v2.0?
The Educational Community License 2.0 is Apache-2.0 with the patent grant limited so a university's entire patent portfolio is not licensed by one contributor dropping code in. Keep copyright, license, and NOTICE. State changes. You will meet it on Sakai, Kuali and other higher-ed software. Do not assume the patent grant is as wide as Apache-2.0.
What does ECL-2.0 require when you ship a product?
You meet the notice condition when each ECL-2.0 component's copyright line and license text appear in the material the recipient actually gets. You are done for a hosted service that never hands out a copy. Running the software for users over a network does not, by itself, trigger a notice duty. You are covered for a desktop, mobile or on-premise build when the notices sit inside the artifact. An about screen or a bundled licenses file both work.
Does ECL-2.0 require me to open my own source?
ECL-2.0 does not force you to open your own source. There is no copyleft here unless a later clause in this text says otherwise.
How do I attribute ECL-2.0 in a product I ship?
Attribution for ECL-2.0 means the copyright line and the license text travel with every copy a recipient actually gets. That can be an about screen, a licenses file inside the installer, or a notice in the container image. A public page helps a buyer audit the inventory. It does not replace notices inside the artifact. If you copied files into your own repository, the header on those files still has to stay.
Is a website notice enough for ECL-2.0?
No. ECL-2.0 talks about copies. A public attestation page is the honest list for procurement. The condition is met when the notices sit in the material you hand over. Put them in the installer, the about screen, or a licenses file inside the binary, then keep the same texts on the page.
Do transitive ECL-2.0 dependencies count?
Yes. The condition follows the code, not the package you chose by name. If the lockfile pulled in ECL-2.0 transitively and you distribute that tree, those notices travel too. Listing only direct dependencies is how teams miss the duty.
How is ECL-2.0 different from Apache License 2.0?
ECL-2.0 asks this: ECL-2.0 is Apache-2.0 with a narrower patent grant aimed at universities. Notice and NOTICE-file rules still apply. Apache License 2.0 asks this: Permissive like MIT, plus an express patent grant. The catch is the NOTICE file: it has to travel inside the binaries you ship. Open the Apache License 2.0 page for what that license requires when you ship. Do not treat the SPDX ids as interchangeable because the short names look similar.
Where do I record ECL-2.0 for a buyer?
ECL-2.0 is a notice license in the catalog, so a component under it needs license text attached before it counts as live on your published page. SourceTrust fetches the published artifact, extracts the license file, and compares that text against the declared SPDX id. A match fills the text in. Every other outcome waits for a person. The stored text is what your page and each export file carry.
