Properties
[edit]The generic software properties sometime follow conventions that are different when they are about FLOSS.
based on
[edit]| Title | ID | Data type | Description | Examples | Inverse |
|---|---|---|---|---|---|
| based on | P144 | Item | based on: the work(s) or inputs used as the basis for subject item; for fictional analog use P1074 | RStudio server Professional Edition <based on> RStudio | derivative work |
When a proprietary software (Q218616) such as RStudio server Professional Edition (Q25936207) is based on (P144) a free and open-source software (Q506883) such as RStudio (Q4798119) it either means that either:
- the proprietary software is published by a third party because it is based on a software licensed under a permissive free software license (Q1437937)
- the proprietary software is published by the copyright owners of the base software because it is licensed under a copyleft (Q133475) license
developer
[edit]| Title | ID | Data type | Description | Examples | Inverse |
|---|---|---|---|---|---|
| developer | P178 | Item | video game developer and software developer: organization or person that developed the item | Loomio <developer> FLOSS contributor | - |
The developer (P178) is an individual or an organization contributing modifications to the code base (there can be more than one developer). If a developer is no longer active, the end time (Q24575125) must be set. There must be at least one reference, preferably to a commit in the source code repository. The generic developer FLOSS contributor (Q25340898) is intended to group all individuals that are not otherwise affiliated to an organization.
ranking
[edit]| Title | ID | Data type | Description | Examples | Inverse |
|---|---|---|---|---|---|
| developer with qualifier ranking | P1352 | Quantity | ranking: ranking of the developer when comparing the number of commits over the past six months | Hunspell <developer> Red Hat <ranking> 1 | - |
number of participants
[edit]| Title | ID | Data type | Description | Examples | Inverse |
|---|---|---|---|---|---|
| developer with qualifier number of participants | P1132 | Quantity | number of participants: the number of developers actively contributing to the software | Loomio <developer> Loomio Cooperative Limited <number of participants> 7 | - |
A developer is active if they contributed in the past six months. A software will evolve within six months, unless it is no longer maintained.
The source code repository URL (P1324) maintains a precise census of the active developers on any given Free Software (except for the rare cases when there is no version control system). Obtaining an inventory of the individual committers, in the case of a Git (Q186055) repository, can be done with the following oneliner:
$ git log --no-merges --pretty='%aN <%aE>' --since '6 months ago' | sort | uniq -c | sort -rn | nl
1 373 James Kiesel <[email protected]>
2 136 Robert Guthrie <[email protected]>
3 117 Hannah Salmon <[email protected]>
...
Some Free Software projects carefully maintain the affiliation of their committers and verifying the number of participants for each organization can be done with the following onliner (or something equivalent depending on the version control system):
$ git log --no-merges --pretty='%aN <%aE>' --since '6 months ago' | sort | uniq | git -c mailmap.file=.organizationmap check-mailmap --stdin | sort | uniq -c | sort -rn | nl
1 7 Loomio Cooperative Limited <[email protected]>
2 7 FLOSS Contributor <[email protected]>
If a developer is an organization, the number of participants (P1132) qualifier must be set to the number of employees contributing modifications to the code base (i.e. not counting employees who have not contributed any change but who may have worked on marketing or sales).
There must be a reference URL (P854) to the source code repository URL (P1324) commit hash from which the number of participants can be verified.
When the developer is an individual, the number of participants (P1132) must not be set.
end time
[edit]| Title | ID | Data type | Description | Examples | Inverse |
|---|---|---|---|---|---|
| end time | P582 | Point in time | end time: the software ceased to be developed | udev <end time> 2012 | - |
When a Free Software development activity slows down, even if it has not seen any change in years, there always is the possibility that it is revived at a later time and there must not be an end time (P582) statement.

instance of
[edit]| Title | ID | Data type | Description | Examples | Inverse |
|---|---|---|---|---|---|
| instance of | P31 | Item | instance of: that class of which this subject is a particular example and member; different from P279 (subclass of); for example: K2 is an instance of mountain; volcano is a subclass of mountain (and an instance of volcanic landform) | Loomio <instance of> free and open-source software | - |
| instance of | P31 | Item | instance of: that class of which this subject is a particular example and member; different from P279 (subclass of); for example: K2 is an instance of mountain; volcano is a subclass of mountain (and an instance of volcanic landform) | Loomio <instance of> free software | - |
| instance of | P31 | Item | instance of: that class of which this subject is a particular example and member; different from P279 (subclass of); for example: K2 is an instance of mountain; volcano is a subclass of mountain (and an instance of volcanic landform) | Loomio <instance of> open-source software | - |
| instance of | P31 | Item | instance of: that class of which this subject is a particular example and member; different from P279 (subclass of); for example: K2 is an instance of mountain; volcano is a subclass of mountain (and an instance of volcanic landform) | Loomio <instance of> public domain | - |
Every software that is an instance of either free and open-source software (Q506883), free software (Q341), open-source software (Q1130645) or public domain (Q19652) is in the scope of the FLOSS project. Since free and open-source software (Q506883) is a subclass of (P279) free software (Q341) and open-source software (Q1130645), it is redundant for a software to be both an instance of (P31) free and open-source software (Q506883) and free software (Q341) or open-source software (Q1130645).
license
[edit]| Title | ID | Data type | Description | Examples | Inverse |
|---|---|---|---|---|---|
| copyright license | P275 | Item | copyright license: license under which this copyrighted work is released | Inkscape <copyright license> GNU General Public License, version 2.0 | - |
The copyright license (P275) should not be set to GNU General Public License (Q7603) because GNU General Public License, version 1.0 (Q10513452), GNU General Public License, version 2.0 (Q10513450) or GNU General Public License, version 3.0 (Q10513445) is more specific. However, an operating system (Q9135) that is a subclass of a GNU variant (Q1475825) will have a GNU General Public License (Q7603) license with no version specified because it may vary depending on which software it includes.
The copyright license (P275) should not be set to BSD licenses (Q191307) because it is a license scheme, use 1-clause BSD License (Q19292556), 2-clause BSD License (Q18517294), 3-clause BSD License (Q18491847) or 4-clause BSD License (Q21503790) instead. See https://w.wiki/32$q for items that need fixing.
The copyright license (P275) should not be set to GNU Lesser General Public License (Q192897) because it is a license scheme, use GNU Library General Public License, version 2.0 (Q23035974), GNU Lesser General Public License, version 2.1 (Q18534390) or GNU Lesser General Public License, version 3.0 (Q18534393) instead. See https://w.wiki/32$r for items that need fixing.
The copyright license (P275) should not be set to Mozilla Public License (Q308915) because it is a license scheme, use Mozilla Public License, version 1.0 (Q26737738), Mozilla Public License, version 1.1 (Q26737735) or Mozilla Public License, version 2.0 (Q26737734) instead. See https://w.wiki/332w for items that need fixing.
This property must not have any qualifier. In particular the software version identifier (P348) qualifier should be removed when it is redundant with the version information embedded in the GPLv2 or GPLv3 item.
The reference should be the URL of the file from the source code repository URL (P1324) which contains the text of the license.
start time / end time
[edit]| Title | ID | Data type | Description | Examples | Inverse |
|---|---|---|---|---|---|
| copyright license with qualifier start time | P580 | Point in time | start time: time an entity begins to exist or a statement starts being valid | VLC media player <copyright license> GNU General Public License, version 2.0 <start time> 2001 | - |
| copyright license with qualifier end time | P582 | Point in time | end time: moment when an entity ceases to exist or a statement stops being valid | VLC media player <copyright license> GNU General Public License, version 2.0 <end time> 21 December 2011 | - |
In the absence of start time (P580) and end time (P582) qualifiers, the copyright license (P275) is assumed to cover the lifetime of the work. If the licensing terms of the software change, the period during which a particular license is valid must be set with the start time (P580) and end time (P582) qualifiers. The latest license should have a preferred rank, and only a start time (P580) qualifier. See VLC media player (Q171477) for instance.
movement
[edit]| Title | ID | Data type | Description | Examples | Inverse |
|---|---|---|---|---|---|
| movement | P135 | Item | cultural movement: the software project supports a movement. For instance when a software belongs to the GNU Project (Q7598), it implicitly supports the free software movement (Q1076638) | GNU social <movement> free software movement | - |
A software may also implicitly belong to a movement (either well known or de-facto such as privacy movement (Q25961579)). For instance The Amnesic Incognito Live System (Q2801412) belongs to the privacy movement (Q25961579) not only because its official website (P856) is focused on privacy: it also is mentioned as such in cryptoparty.in.
source code repository
[edit]| Title | ID | Data type | Description | Examples | Inverse |
|---|---|---|---|---|---|
| source code repository URL | P1324 | URL | repository and source code: public source code repository | Loomio <source code repository URL> https://github.com/loomio/loomio | - |
| source code repository URL with qualifier version control system | P8423 | Item | version control system: version control system used by a content repository | Loomio <source code repository URL> https://github.com/loomio/loomio <version control system> Git | - |
| source code repository URL with qualifier web interface software | P10627 | Item | web user interface: software that generates the web interface for the source code repository | Loomio <source code repository URL> https://github.com/loomio/loomio <web interface software> GitHub | - |
| source code repository URL with qualifier download URL | P4945 | URL | download: URL which can be used to download a work | Mozilla Application Suite <source code repository URL> no value <download URL> https://archive.mozilla.org/pub/vcs-archive/cvs-main.tjz | - |
| source code repository URL with qualifier website username or ID | P554 | String | username: username[:password] required to access the repository | TkRev <source code repository URL> http://tksvn.tigris.org/svn/tksvn/trunk <website username or ID> guest:guest | - |
The source code repository URL (P1324) should be the URL of the source code repository that can be read by a version control system. The version control system (P8423) qualifier identifies the version control system that accepts the URL (e.g. Git (Q186055), Apache Subversion (Q46794), Mercurial (Q476543)), or is no value if the URL is not accepted by a version control system (e.g. if the URL is only intended to be used in a web browser).
When available, a URL that does not require authentication should be used. If a URL requires authentication, it is not verifiable and should be avoided, unless it is the only URL available. For instance https://secure.phabricator.com/diffusion/P/phabricator.git should be used instead of ssh://[email protected]/diffusion/P/phabricator.git. When a URL requires authentication and the user and password are publicly available, they should be set as the website username or ID (P554) qualifier as user:password or user if no password is necessary. For instance TkRev (Q3530050) can be checked out with svn checkout http://tksvn.tigris.org/svn/tksvn/trunk tksvn --username guest --password guest and the website username or ID (P554) is set to guest:guest.
If the URL provides a human-readable web interface to browse the content of the source code repository, the web interface software (P10627) qualifier identifies the web interface that it provides (e.g. GitHub (Q364), GitLab (Q16639197), cgit (Q28974765), Gitweb (Q97460957), ViewVC (Q927548), Apache Allura (Q16242762)), or is no value otherwise.
If the URL that is used with the version control system does not provide a human-readable web interface, but a human-readable web interface for the repository is available at a different URL, a separate source code repository URL (P1324) statement may be entered for each URL. The version control system (P8423) qualifier would be no value for a URL that is not accepted by a version control system, and the web interface software (P10627) qualifier would be no value for a URL that does not provide a human-readable web interface.
Any kind of version control is eligible, even if managing software is not the primary purpose. For instance Search Autodescription (Q21281236) has a source code repository URL (P1324) set to https://en.wikipedia.org/wiki/MediaWiki:Wdsearch-autodesc.js which is a MediaWiki (Q83) page associated with a version history. The web interface software (P10627) to access it is MediaWiki (Q83).
When there is no public version control repository for the software but the source for each version is available as a separate download (e.g. as a tar.gz file, zip file, etc.), the download URL (P4945) qualifier of the corresponding software version identifier (P348) statement is set to the URL of the file. If there exists a downloadable file with a copy of a decommissioned source code repository, its URL may be set as the download URL (P4945) qualifier of a source code repository URL (P1324) statement with no value as its repository URL; see Mozilla Application Suite (Q538588) for an example.
Although there is an authoritative source code repository most of the time, there may exist long lived forks that evolve in parallel and cherry pick commits from one another, for instance libavcodec (Q217647). In such cases more than one source code repository should be added.
When a software has more than one source code repository, they should all be listed. When all the source code repositories are listed on a web page, that page can also be used. However, if the web page also lists unrelated source code repositories, it should not be used because it is not verifiable. For instance Ceph (Q4035967) has such a page in https://github.com/ceph/, which shows the main repository https://github.com/ceph/ceph but also dozens of others which do not contain Ceph source code.
When there are multiple source code repositories, one of them should have the preferred rank. Ideally the repository with the preferred rank has a web interface as well as a machine readable interface (for instance https://notabug.org/vimuser/libreboot.git can be browsed by a human or git clone) and is the primary source from which facts about the software can be verified (license, authors, etc.). The software for which the the preferred rank is missing should be looked at from time to time.
This property should be used by the sofware infobox.

Queries
[edit]Introduction
[edit]Performances
[edit]The query will timeout after 30 seconds and this limit forces the query to use various tricks to resolve as quickly as possible.
- Prefer Union to Values. The following:
{
?floss p:P31/ps:P31/wdt:P279* wd:Q506883.
} Union {
?floss p:P31/ps:P31/wdt:P279* wd:Q341.
} Union {
?floss p:P31/ps:P31/wdt:P279* wd:Q1130645.
}
is equivalent to
?floss p:P31/ps:P31/wdt:P279* ?kind .
VALUES ?kind { wd:Q506883 wd:Q341 wd:Q1130645 }
It is tempting to use the Values because it is less redundant. Unfortunately it takes longer and will timeout.
Working on a specific set of items
[edit]When the focus is narrower than all FLOSS, it is possible to restrict the results by adding the list of items of interest in the query, right after the Union group, like so:
VALUES ?floss { wd:Q191782 wd:Q798540 wd:Q48524 wd:Q1102277 etc }
List all FLOSS
[edit]List all Item with instance of (P31) being anything which is a subclass of (P279) of free and open-source software (Q506883), free software (Q341) or open-source software (Q1130645). Although wdt:P31 looks equivalent to p:P31/ps:P31, it only finds the truthy statements and will therefore miss items for which there is an instance of (P31) with a preferred rank that is not about license (Q79719) (see for instance Blender (Q173136), in which case it will never be derived from the desired license items.
