Depicts is a feature part of Structured data. It was enabled on Wikimedia Commons on April 23, 2019 and will be extended with more features in the following weeks.
How to add a Depicts statementEdit
To add a depicts statement:
- On the file you wish to add information to, select the "Structured data" tab, located below "Open in Media Viewer" and to the right of "File information"
- Select edit, or simply start typing in the search box to get started
- For each depicted item in the image, find the appropriate item from Wikidata and select it
If you have trouble finding the right Wikidata item, test alternative spellings, or try navigating from a Wikipedia page about the item (using the "Wikidata item" link in the "Tools" menu on the left of the Wikipedia page).
If there is no Wikidata item associated with the subject depicted, consider whether it meets Wikidata's Notability standards. If so, consider creating a new item. If not, choose a more generic item which includes your subject as an example.
What items to addEdit
Please only tag conservatively at first, while the community learns how to use this tool best.
If there are multiple items clearly and deliberately depicted by the media file, all should be added as separate depicts statements, within reason. For files that depict dozens or hundreds of items (e.g., movies) only list those items which are most prominent.
If groups of the multiple depicted items are a common grouping, and have a grouped item on Wikidata, the grouped item should also be added as a depicts statement. For example File:Bonnieclyde f.jpg depicts: Bonnie and Clyde (Q219937) as well as depicts: Bonnie Parker (Q2319886) and depicts: Clyde Barrow (Q3320282).
There is also an option to mark a particular item as "prominent". This property refers to the item's prominence in the piece of media, so a photo like File:Padova REM concert July 22 2003 blue.jpg depicts singer Michael Stipe, bassist Mike Mills, and guitarist Peter Buck but only Stipe is prominent, as he is clearly visible at the center of the photo, whereas Buck is mostly cropped out of the right-hand side and Mills has his back turned to the camera.
What items not to addEdit
It has also been suggested (for the purposes of good coverage in the search function) to tag more generic items that have your specific item as an instance or subclass. In the M87* example above, you could also imagine adding Depicts: supermassive black hole (Q40392) and Depicts: black hole (Q589), because M87* (Q3841190) is an instance of a subclass (supermassive black hole (Q40392)) of black hole (Q589). This would contrast with how we use categories on Commons, where we try to prevent overcategorization. These generic tags should not currently be added. If this guideline changes, these more generic items may later be inferred from the relationships in the structured data on Wikidata.
Parts of a bigger itemEdit
The depiction of a face (Q37017) usually implies the presence of a nose (Q7363), nostril (Q858590), and nasal hair (Q1899093). It is not necessary to list them all on every portrait. Instead just state that the portrait depicts the person in the portrait. Anatomical or other compositional relationships can already be modelled within Wikidata.
Items expected to be covered by other statementsEdit
Many media include incidental items, actions, locations, context, formatting choices, or background, that are not the primary items depicted. As structured data on Commons expands, we expect to have additional properties enabled where these extra items can be specified. In the meantime, it is best to refrain from specifying these as depicts, unless they are central to the purpose of the media.
For example, some expected properties include:
- depicted in background
- formatting (e.g. monochrome images or daguerreotypes)
- photographer or artist
Adding depicts statements using bots is not possible at the moment, but this function will be implemented later.
You can add Depicts statements via the default upload method, UploadWizard.
For other upload methods, support may be added in the future − you may refer to the respective bug tracker of each tool for more information.
There are currently no gadgets or mass-edit tools supporting the addition (such as VisualFileChange.js or Cat-a-lot) upporting Depicts statements. Such gadgets may be developed by volunteers in the future.
Editing depicts statements shows up in RecentChanges.
Searching depicts statementsEdit
Advanced search, allowing to retrieve pictures with Depicts using "normal" full-text search, is in development.
Later on, there will likely be a way to query depicts through SPARQL (T141602), as well as access through Lua.
You can retrieve statement using the
wbgetentities module with the entity ID. For each file there is a Wikibase entity ID
XXXX being the page_id. So for example, File:Monument Demba et Dupont.jpg has the page ID
41837276, so the entity ID is
M76359368, and you can query wbgetentities&ids=M76359368. An easy way to get the Mid is to use the API action=query&prop=info&titles=File:File:Monument_Demba_et_Dupont.jpg (the page ID is provided by the
