You can help! Data modeling is a community effort. Improve the guidelines, provide (additional) examples, or propose other data models for community discussion. Visit the talk page to discuss this process in general.

This page contains an overview of how to model information (metadata) about files on Wikimedia Commons in Structured Data.
The basics: structured data for every Commons file
[edit]
The following structured data is relevant for every file on Wikimedia Commons. This structured data roughly corresponds with the information stored in the Information template, a general usage infobox template to describe files in wikitext.
If the above structured data is added to a file, the file's wikitext description can be simplified as follows:
An overview of further structured data property statements, that are in active use can be found here: Commons:Structured data/Properties table
The specifics: case examples of common Commons files
[edit]
Own work upload directly to Commons
[edit]
To describe a simple {{Own}} work upload directly uploaded by the author or {{Self}}-licensed by the uploader:
-
File caption: one or more short description(s) of the file + language
-
Date: inception (P571), see Commons:Structured data/Modeling/Date
-
Source of the file: source of file (P7482) → original creation by uploader (Q66458942)
-
Creator of the file: creator (P170) → "some value" to indicate the creator doesn't have a Wikidata item. Qualified with:
-
Copyright and licenses: copyright license (P275) and copyright status (P6216), see Commons:Structured data/Modeling/Copyright
[edit]
To describe an upload directly uploaded from a platform: (Preferably all uploads were done by a tool or bot, for consistency)
-
File caption: one or more short description(s) of the file + language
-
Date: inception (P571), see Commons:Structured data/Modeling/Date
-
Source of the file: source of file (P7482) → file available on the internet (Q74228490) to indicate the source
-
Creator of the file: creator (P170) → "some value" to indicate the creator doesn't have a Wikidata item. Qualified with:
-
Copyright and licenses: copyright license (P275) and copyright status (P6216), see Commons:Structured data/Modeling/Copyright

Pronunciation
[edit]
-
Copyright and licenses: copyright license (P275) and copyright status (P6216), see Commons:Structured data/Modeling/Copyright
-
Type: instance of (P31) → pronunciation file (Q108167708)
-
Language: language of work or name (P407) → e.g. French (Q150)
-
Transcription: audio transcription (P9533) → "<verbatim>" to describe what is pronounced
-
Recording date: recording date (P10135)
-
Who recorded it: recordist (P10893)
-
Who pronounced it: spoken by (P10894)
-
IDs: e.g. Lingua Libre ID (P10369) → "<id>" to describe the source identifier if applicable
How to model more specific types of files
[edit]
-
Maps Work in progress
[edit]
Here, we look at specific types of metadata for a file:
-
Date Work in progress
GLAM
[edit]
In some cases, large-scale content contributions mainly originating from Galleries, Libraries, Archives, and Museums (GLAM) use more specific data models.
It is highly recommended that all file metadata also complies with the general, basic data modeling recommendations listed above. This will make sure that all data on Wikimedia Commons can be uniformly searched and queried across the entire platform.
Content specific properties may be added, like:
-
The Metropolitan Museum of Art: The Met object ID (P3634) → "<description>"
-
iNaturalist: iNaturalist observation ID (P5683) → "<id>"
-
Digital Public Library of America → Please see: Commons:Digital Public Library of America/Modeling
-
Biodiversity Heritage Library → Please see: Commons:Biodiversity Heritage Library/Modeling
Bots
[edit]
Some bots automatically populate SDC data based on metadata in Commons templates.
-
BotMultichill adds properties for various IDs.
-
BotMultichillT populates date, coordinates, camera, source, copyright and author.
-
SchlurcherBot adds various types of SDC to files per the modelling described here.
-
JarektBot adds Wikimedia VRTS ticket number (P6305) and digital representation of (P6243) using QuickStatements.
-
AliciaFagervingWMSE-bot uploads creator (P170), inception (P571), coordinates of the point of view (P1259), depicts (P180), and participant in (P1344) to Wiki Loves Monuments files from Sweden, Israel, and Poland.
-
METbot adds The Met object ID (P3634) and collection (P195) to the Metropolitan Museum of Art files.
-
GeographBot uploads different SDC information to Geograph Britain and Ireland files.
-
DPLA bot added structured data claims to DPLA items.
-
XRayBot adds/updates coordinates of depicted place (P9149) (and others) - but only to XRay's own photographs.
-
NikkiBot adds structured data to Lingua Libre uploads.
-
FlickypediaBackfillrBot adds structured data to Flickr files.
-
Emijrpbot adds structured data for various camera properties from Exif data.
