Deze pagina is een korte Nederlandstalige samenvatting van de richtlijn Commons' Project Scope.

Wikimedia Commons (this site) is a repository of free, educational media files used by Wikipedia, other Wikimedia projects, and others. The free part is very important – it's a founding principle of Commons that we should only host content that can be used by anyone for any purpose.

Commons does not host fair use content or other non-free content, such as most content published on the Internet and elsewhere. Commons does not host encyclopedic articles or other non-media content. We also don't host content unless it has educational value.

Niet alle bestanden kunnen op Commons worden geüpload. Bestanden moeten voldoen aan de volgende criteria:

Alleen bestanden in het publiek domein of onder een vrije licentie

It's a founding principle of Commons that we should only host content that can be freely used by anyone for any purpose. Therefore, Commons can only accept two types of content:

  1. Content whose copyright holder has explicitly agreed to allow anyone to use it for any purpose
  2. Content that is not protected by copyright

  Recently created works such as photos, drawings and videos are almost always protected by copyright – even if there is no copyright notice. Copyright protection means that the copyright holder has the right to specify who may use the work and how they may use it. One way to specify this is by using a copyright license. Only the copyright holder can grant a license. The copyright holder is usually the person who created the work, such as a photographer or painter. Wikimedia Commons only accepts copyrighted works if they are covered by a license that allows anyone to use them freely for any purpose.

  Commonly used free licenses include Creative Commons Attribution   and Creative Commons Attribution Share-Alike    without Non-Commercial   or No-Derivatives   restrictions, but there are also other accepted licences.

  Common examples of licenses that are not accepted on Commons include all Creative Commons licenses with Non-Commercial   or No-Derivatives   restrictions.

  Content that is not protected by copyright is said to be in the public domain. Public domain content is accepted at Commons, but you must be able to explain why the content is in the public domain. Common reasons include that the content is too simple to be protected by copyright, that the copyright expired or that the copyright holder explicitly released it into the public domain. Merely making a work accessible to the public does not mean that it is released into the public domain.

  Copyrighted content without any indication of a free license is not accepted, even in the absence of a copyright notice. Content explicitly marked as non-free, including content with All Rights Reserved or fair use notices is not accepted.

Alleen bestanden met een educatieve functie

Wikimedia Commons only hosts content that is useful for educational purposes. This means content that could be used by Wikipedia, other Wikimedia projects, or other projects that provide knowledge, instruction or information. Files don't have to be in use on any other project to be hosted here, but they must have a reasonable potential use.

  Voorbeelden van bestanden die realistisch gezien niet bruikbaar zijn voor educatief gebruik:

  • Privé-afbeeldingen zoals foto's van feestjes, foto's van uzelf of vrienden, vakantiefoto's, enz. Er zijn verschillende projecten op internet waar zulke afbeeldingen wel welkom zijn, zoals. Privé-afbeeldingen worden niet toegestaan, zelfs niet als ze gebruikt worden in een gallerij op een gebruikerspagina op Commons of elders.
  • Zelfgemaakte kunst, tekeningen of fancraft zonder duidelijke educatieve functie.
  • Bestanden geupload met als doel vandalisme of persoonlijke aanvallen op een andere gebruiker. Bestaande symbolen en ontwerpen die zijn of worden geassocieerd met nationalistische, religieuze of racistische doelen of organisaties zijn toegestaan, ook als ze voor bepaalde groepen beledigend over kunnen komen.
  • Elke vorm van reclame of zelfpromotie.
  • Bestanden die geen educatieve toevoeging vormen voor de al bestaande collectie bestanden over hetzelfde onderwerp op Commons. Dit geldt met name voor bestanden met slechte of matige kwaliteit.

For details, see the full project scope policy.

Alleen mediabestanden

  Commons bevat alleen mediabestanden, zoals foto's, gescande afbeeldingen, diagrammen, animaties, geluidsbestanden (muziek, ingesproken bestanden) en video's.

  Commons does not host encyclopedic articles or other plain-text content, and it does not host computer programs in any format (including executable files and source code).

Alleen bestanden met een onder vrije licentie toegestaan formaat

Currently the following formats are allowed:

  • Images: SVG (for vector graphics), PNG (lossless format), JPEG (for photographs), GIF ("semi"-lossless format, but PNG is preferred), TIFF (lossless format, but PNG is preferred), XCF (allows layers and text).
  • Audio: Ogg-container (using FLAC, Speex, Opus or Vorbis codecs with file extension .oga), MIDI, WAV (16-bit PCM format and 32-bit IEEE uncompressed format) or FLAC (.flac).
  • Video: WebM using the VP8 video codec with Vorbis for the sound, or Ogg using the Theora video codec. New software supports file extension .ogv for Theora video without or with Vorbis audio, RFC 3534 .ogg is still usable instead of RFC 5334 .ogx for Theora video with other Ogg audio codecs - Help:Converting video.
  • Multipage documents (books, journals, magazines, etc.): PDF and DjVu.

Currently disabled

While SXW, SWC, SXD, and SXI ( 1.x), as well as ODT, ODS, ODG, and ODP (OpenDocument) are theoretically permissible under the similar provisions to Commons:Scope#PDF_and_DjVu_formats these formats are currently disabled because we are currently unable to prevent people from hiding harmful or otherwise impermissible content inside OpenOffice's ZIP based container format.

For a longer list of unsupported file types, see Commons:File_types#Unsupported_file_types.


If you have questions about whether a certain file is within the project scope of Commons, you can ask at the help desk.
