Policies or guidelines regarding depicts

[edit]

Commons:Project scope

[edit]
official policy
Does not include significant elements regarding the importance of image description at large, or depicts in particular, in the scope

Commons:First steps/Quality and description

[edit]
Community guidelines
Does not include mention to depicts
Does include suggestions with regards to description (which may be extended to depicts generally, but again no mention of structured data)
Description of the content. What do you see, hear, or otherwise perceive? If it's an artwork, please provide brief historical background. In case of scientific data, a brief scientific abstract of the file. If you have detailed information about an image, for example the name of the species or the size of the object, please add it. Especially with mineral images, including the size is helpful. Stating where a photograph was taken never hurts and is often essential, as for almost any non-astronomical photograph taken outdoors, among others. Descriptions can be in any language, but it is always a good idea to include an English description as well. If you can write in more than one language, consider adding the description in all of them.

Over-categorization

Commons:Depicts

[edit]
project community guidelines - not policy, but in progress guidelines
Include fairly detailed guidelines about what to add as depicts and what to not add.

What items to add

[edit]

Please only add "depicts" statements conservatively at first, while the community learns how to use this tool best.

Be as specific as you can. For example if a media file such as File:Black hole - Messier 87 (cropped).jpg, the best primary statement is Depicts: Pōwehi (Q3841190).

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).

Prominence

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. When querying the structured data, prominent statements can be found be searching for statements with rank "preferred".

What items not to add

[edit]
Generic items
Do not add an item as depict if there is already one which is a subclass of the one you want to add.

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 Pōwehi (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 more specific depicts statements already exist. 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 item

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 statements

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:

  • location
  • depicted in background
  • clothing
  • format (e.g. monochrome photography, daguerreotype, oil painting, portrait)
  • season/date/time
  • photographer or artist
  • genre (e.g. modern art)

Commons talk:Depicts contains quite a few (rather negative feedbacks)

Commons talk:Structured data contains a lot of comments

  • Several notes of interest
There is some confusion among the Commons community about structured data: its purpose, long-term plans, what is and is not possible, ideals for specific types of structured data, how the data relates to existing Commons mechanisms, etc. Most relevant for this exercise is "what constitutes a good depicts statement?" These questions would be helpful to address by clear documentation on Commons (written for a non-technical audience, with a clear venue to ask questions) and a conversation between stakeholders in the future.
