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.

Findings
9 recorded, 6 applied to the record, 0 proposed

The record models the Open Group Test Suite License, an Artistic-style license written to keep the standard test modes of a conformance test suite intact. Verbatim copies may be given away freely; a modified copy must say in each changed file how and when it changed, must rename its non-standard executables and test cases, and must ship the Standard Version alongside them with instructions on where to get it. A reasonable copying fee is allowed, a fee for the package itself is not.

9 findings

  • major Rubric 3 odrl:permission applied

    Clause 1 reads: "You may make and give away verbatim copies of the source form of the Standard Version of this Package without restriction, provided that you duplicate all of the original copyright notices and associated disclaimers." Clauses 3 and 4 allow modification and distribution in object or executable form. Clause 5 allows a reasonable copying fee and aggregation with commercial programs, which supports cc:CommercialUse and dalicc:chargeDistributionFee.

  • major Rubric 4 odrl:prohibition applied

    Clause 5 reads: "You may not charge a fee for this Package itself." dalicc:chargeLicenseFee is therefore prohibited while dalicc:chargeDistributionFee is permitted, which is the distinction the two terms exist for. Clause 8 bars endorsement use of the Copyright Holder's name, so dalicc:promote is prohibited. dalicc:ChangeLicense is prohibited because the text requires the license itself to travel with every copy, which is the reading IscLicense and BSD-3-Clause take of the same clause. The MIT record does not carry the prohibition although its text has the same requirement, so the library is not uniform here.

  • major Rubric 5 odrl:duty applied

    Clause 3 requires "a prominent notice in each changed file stating how and when you changed that file" (dalicc:modificationNotice) and requires you to "rename any non-standard executables and testcases so the names do not conflict with standard executables and testcases, which must also be provided" (dalicc:rename). Clause 4 requires a binary distribution to accompany non-standard executables and test cases with their Standard Version counterparts and with instructions on where to get the Standard Version, which the record carries as cc:SourceCode, the library's closest term for an obligation to make the original available. All three hang off modify and derive; cc:Attribution and cc:Notice hang off distribute as well.

  • minor Rubric 6 dalicc:additionalClauses applied

    Clauses 5, 6 and 7 are quoted: the fee rules, the statement that the scripts and library files supplied to or produced by the package do not fall under its copyright, and the statement that subroutines linked into the package are not part of it. Those three carve-outs decide what the license reaches, and no deontic term expresses them.

  • minor Rubric 6 dalicc:WarrantyDisclaimer applied

    Clause 9 is the disclaimer, quoted without its number. There is no liability clause.

  • info Rubric 7 cc:jurisdiction none

    The text names no legal system and no term, so cc:jurisdiction is dalicc:worldwide and dalicc:validityType is dalicc:perpetual.

  • info Rubric 2 odrl:target applied

    One odrl:AssetCollection of dct:type dcmitype:Software, following MIT. The text licenses a package of test programs and scripts.

  • info Rubric 9 record none

    The consistency check with the axioms of dg_default returned no conflicts. Prohibiting dalicc:chargeLicenseFee while permitting cc:CommercialUse and dalicc:chargeDistributionFee raises no conflict: the axioms relate dalicc:chargeLicenseFee to odrl:commercialize and odrl:sell, neither of which this record permits.

  • info Rubric 10 record none

    The text is the Artistic License with test-suite wording, so the nearest sibling in the library is Artistic-2.0 rather than MIT. The rename and modification-notice duties are what the two have in common.

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.

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.
