The unique identifier for the license in the ScanCode LicenseDB as assigned by scancode-toolkit.
Note that this identifier is permanent and never changes and never goes away once published: no license key is ever deleted.
Instead a license can be marked as deprecated.
A short descriptive name (title) for the license in the ScanCode LicenseDB as assigned by scancode-toolkit.
A long name for the license in the ScanCode LicenseDB as assigned by scancode-toolkit.
When this is “yes”, the license is no longer used. For deprecated licenses, the notes may contain commentaries
and the license key that this license may be replaced by when relevant.
The SPDX Short Identifier for the license if it exists in the SPDX license list at
Otherwise this is an SPDX license reference in the form of LicenseRef-scancode-<license key>.
Alternative (or older, deprecated or obsolete) SPDX Short Identifiers or LicenseRef for the license.
URLs to the standard text of the license.
Notes and comments about the license.
A license category code, assigned by scancode-toolkit, that provides a major grouping for licenses,
generally describing the relationship between the licensor and the licensee. These license categories are not
legally precise, and are only intended to support Software Composition Analysis and usage policy implementations.
An owner is an entity that is the original author or custodian of a software license, and which may be responsible
for the text of the license. This is mandatory and should be set to "Unspecified" if it cannot be determined.
The homepage URL where the license is described.
Other URLs that identify or are related to this license, such as URLs to this license in different open-source projects.
Obsolete links may be kept here, as they may be useful for historical analysis purposes.
The identifier assigned by the OSI to a license for OSI-approved licenses.
A direct commercial license between a supplier and a customer.
Further fact-finding by a Product Team will be necessary to determine how the license conditions apply to use of the software.
This is a Proprietary license that is not Open Source.
A license that offers irrevocable permission to the public to copy and redistribute the work in the same or modified form,
but with the conditions that all such redistributions make the work available in a form that facilitates further modification
and uses the same license terms. A Copyleft license can require code interacting with Copyleft-licensed code to be licensed under
the same license or a compatible license. This is an Open Source license. This category may be described as “Strong Copyleft”.
A license that requires you to redistribute source code, including your changes, and to provide attribution for the software authors.
Your obligation to redistribute source code, including proprietary code linked with code under this license,
is limited according to license-specific rules. This is an Open Source license. This category may be described as “Weak Copyleft”.
A Permissive-style license that contains restrictions regarding the usage of the software (e.g. where the software is not
intended for use in nuclear power plants) or the redistribution of the software (e.g. where commercial redistribution of
the software is not allowed or allowed only with express permission). The Free Software Foundation (FSF) says that a license
with this kind of restriction is not really open source, although the OSI point of view is not that strict.
This is a Proprietary license that is not Open Source.
A license that applies to patents rather than specific software. May be used in conjunction with other software license(s) that
apply to a software component.
A license that requires you to provide attribution for the software authors and may include other conditions.
This is an Open Source license.
A license that does not require a supplier-customer contract, but has specific terms and conditions which a Product Team
is obligated to follow. These terms and conditions may be documented in the code and/or from a webpage where you must accept
the license (i.e. click-through). This is a Proprietary license that is not Open Source.
“Public Domain” as a license category means software that is not restricted by copyright.
This is most often applicable to a software component because the person entitled to control the copyright has disclaimed that
right in a notice (“dedication”) that appears similar to a license. It is possible for software to be in the public domain
because the copyright has expired, but this is rarely relevant for software due to the long duration of copyrights in most jurisdictions.
The rules for disclaiming copyright and copyright expiration dates vary widely by jurisdiction.
A public domain dedication may apply to software code examples on a website, published public domain specifications or
another type of publication. Public Domain is typically treated as similar to an Open Source license even though it is not an
Open Source license.
A license where the software is released through a source code distribution model that includes conditions where the source
can be viewed, and in some cases modified, but without meeting the criteria to be called Open Source.
The most common restriction is for “field of use”. This is a Proprietary license that is not Open Source.
“Unstated License” as a license category means third-party software that has a copyright notice, but no stated license.
Common examples include code snippets from publications and websites. The absence of a license poses a risk that the copyright
owner may assert license conditions at some future time. A Product Team may need to contact the copyright owner to determine the
license conditions, if any.
