License-wide duties

This license states no duties that apply to the work as a whole.

What applies by default

The statements above are the library's reading of this license: each is marked with the sentence it rests on, or as a library convention where the text is not explicit. The statements below are the ones the DALICC reasoner supplies for acts the license says nothing about, from the default rules of the dependency graph it reasons with. Each one names the legal source it rests on. None of it is in the record.

No default rule of that graph reaches this license: it speaks about every act the rules are about.

Further terms

These are the things the license says about itself beyond the acts it permits, forbids and requires: when it ends, how long there is to put a breach right, which law governs it, and so on. A term that comes from the DALICC vocabulary links to its definition.

Patent license ends if you sue
Yes. Not a ban on suing: a patent claim over the work ends the patent license, or the whole license, as the text provides.

Clauses

Warranty disclaimer

Unless required by applicable law or agreed to in writing, Licensor provides the Work (and each Contributor provides its Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness of using or redistributing the Work and assume any risks associated with Your exercise of permissions under this License.

Limitation of liability

In no event and under no legal theory, whether in tort (including negligence), contract, or otherwise, unless required by applicable law (such as deliberate and grossly negligent acts) or agreed to in writing, shall any Contributor be liable to You for damages, including any direct, indirect, special, incidental, or consequential damages of any character arising as a result of this License or out of the use or inability to use the Work (including but not limited to damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses), even if such Contributor has been advised of the possibility of such damages.

Accepting warranty or additional liability

While redistributing the Work or Derivative Works thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty, indemnity, or other liability obligations and/or rights consistent with this License. However, in accepting such obligations, You may act only on Your own behalf and on Your sole responsibility, not on behalf of any other Contributor, and only if You agree to indemnify, defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against, such Contributor by reason of your accepting any such warranty or additional liability.

Additional clauses

The Educational Community License version 2.0 ("ECL") consists of the Apache 2.0 license, modified to change the scope of the patent grant in section 3 to be specific to the needs of the education communities using this license. The original Apache 2.0 license can be found at: http://www.apache.org/licenses/LICENSE-2.0

Findings
12 recorded, 6 applied to the record, 1 proposed

Models the second Educational Community License, which is the Apache License 2.0 with one changed sentence in the patent grant. The record copies the Apache-2.0 record statement for statement and adds the express patent grant as a permission and patent retaliation as a prohibition, which the Apache-2.0 record does not yet carry. A reader comparing the two records should read the quoted patent clauses, because that is the whole of the difference between the licences.

12 findings

  • info Rubric 1 spdx:licenseId none

    File name, license id, SPDX id and IRI agree. cc:legalcode and dct:source point at the single seeAlso URL; the text itself also names http://www.apache.org/licenses/LICENSE-2.0 as the unmodified parent, which is quoted rather than linked so the record resolves to the ECL text.

  • minor Rubric 2 odrl:target applied

    Asset types copied from the Apache-2.0 record (dalicc:CreativeWork, dcmitype:Dataset, dcmitype:Software): the licence grants rights in 'the Work', defined as any work of authorship in Source or Object form.

  • major Rubric 3 odrl:permission applied

    Section 2 grants a 'perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare Derivative Works of, publicly display, publicly perform, sublicense, and distribute the Work', so the record carries reproduce, distribute, modify, derive, display, present, grant use, commercial use, derivative works, modified works, the distribution fee and dalicc:ChangeLicense with a dalicc:compliantLicense duty for the section 4 allowance of different terms on Your modifications. dalicc:patentGrant is added for section 3, which the Apache-2.0 record omits.

  • major Rubric 4 odrl:prohibition applied

    dalicc:promote for section 6 ('This License does not grant permission to use the trade names, trademarks, service marks, or product names of the Licensor') and dalicc:patentRetaliationTermination for the second sentence of section 3, which ends the patent licence when the licensee sues.

  • major Rubric 5 odrl:duty applied

    Section 4 conditions redistribution, so cc:Attribution and cc:Notice hang off distribute, and dalicc:modificationNotice joins them on modify and derive: 'You must cause any modified files to carry prominent notices stating that You changed the files'. This is the Apache-2.0 record's placement, unchanged.

  • minor Rubric 5 odrl:duty proposed

    Section 4(d) requires the NOTICE file to travel with Derivative Works. dalicc:includeNoticeFile would express it, but the Apache-2.0 record does not carry it and this record follows its sibling; adding it to both at once is the consolidation agent's call.

  • minor Rubric 6 dalicc:WarrantyOrLiabilityAcceptance applied

    Sections 7, 8 and 9 are quoted verbatim into dalicc:WarrantyDisclaimer, dalicc:LiabilityLimitation and dalicc:WarrantyOrLiabilityAcceptance, word for word identical to the Apache-2.0 record.

  • major Rubric 6 dalicc:additionalClauses applied

    The narrowed patent sentence is quoted in full because it is the reason the licence exists: 'Any patent license granted hereby with respect to contributions by an individual employed by an institution or organization is limited to patent claims where the individual that is the author of the Work is also the inventor of the patent claims licensed, and where the organization or institution has the right to grant such license under applicable grant and research funding agreements. No other express or implied licenses are granted.'

  • info Rubric 7 cc:jurisdiction none

    No legal system and no term are named: dalicc:worldwide and dalicc:perpetual.

  • gap Rubric 8 record none

    No vocabulary gap of its own. dalicc:patentGrant and dalicc:patentRetaliationTermination were defined by the 2026-09-15 review and applied to no record then; this record is one of the first to use them, so the consolidation should update their skos:note.

  • info Rubric 9 record none

    The consistency check of app.services.composer, run with the 39 axioms of licensedata/dependencygraph/dg_default.ttl, returned no conflicts.

  • info Rubric 10 record none

    Against Apache-2.0 the record differs only by dalicc:patentGrant, dalicc:patentRetaliationTermination and the quoted patent clauses. Against ECL-1.0 it adds the patent grant and retaliation and drops the rename duty. A separate record is justified: the compatibility answer for a patent claimant differs.

History

This license model has 2 versions. Version 2 is the one served today; every earlier version keeps its own address, so a conclusion drawn from one of them can still be checked against it.

    • added dct:license <https://creativecommons.org/licenses/by/4.0/>

Every change names the reason behind it: a finding of the content review, one of its library-wide decisions, the metadata that review wrote onto every record, or a hand edit. None of it is legal advice.

Nothing on this page is legal advice. What a license means is decided by its text; ask a legal advisor before you rely on it.
