Tracked in Phabricator
Task T173979

This page collects interesting media files (and other interesting phenomena) on Wikimedia Commons, as inspiration for modelling these cases in structured data in the future.

How to use this page?
  1. Please re-organize the page as you see fit!
  2. Please add your own examples!
  3. Please improve the explanations for the files! (Why is the file interesting? Which modelling challenges are there?)

Variations on the {{Information}} template[edit]

  • Art photo (via PierreSelim)

  • Object photo (via PierreSelim).
    The {{Object photo}} template is special in the way in which it draws metadata from its encompassing category. It shows metadata for both the (usually three-dimensional) object and for the photograph taken of that object.

  • A multi-licensed image on Wikimedia Commons, with a custom {{EthnologyItemMHNT}} Information template. (via PierreSelim)

  • Specimen (via PierreSelim)

  • Specimen and Information field (via PierreSelim)

  • Structured information partially matches the information templates.Sees for instance dimensions and author.

  • Structured information is hidden in the template

  • Structured information with non-standard parameter names like "commons_description"

  • Structured information with parameter names in other languages

  • Incorrect language template

  • Semi-structured description generated by bulk upload

  • Information template with additional description/informations

  • Information template with additional description/informations (inscription)

  • Information template with additional description/informations (sculpture)

  • Information template with additional description/informations (sculpture)

  • User templates with categorization

  • additional description outside information template

  • 6 different extracted images

Interesting examples in terms of licensing and copyright[edit]

  • Photo of an object that is a potentially copyrighted element (via Yann)

  • CC0-licensed, from Gallica.fr (via Yann)

  • Photo from outside Commons, with potentially copyrighted element (scan from a book?) (via Yann)

  • Derivative from a video (via Yann)

  • Collage of many different source images, with different licenses (via El Grafo)

  • A map built with information that is sourced elsewhere - to be solved with references? (via Nikkimaria)

  • Photograph and description dual-licensed as CC-BY-SA + GFDL, object is public domain. (Uses a custom template)

  • Author is identified as "N. Brown", about whom little seems to be known.

  • Author apparently isn't the copyright holder.

  • Photo multi-licensed under both free and non-free licenses (the latter using a custom template)

  • Depicts an unlicensed drawing, included as de minimis.

  • Verbose credit line generated by a template

  • Credit line including a required title

  • User license and additional fields at information template

  • An image with different copyright status for the object depicted (public domain for different reasons in source country and US) and for the photo of the object (CC-BY-SA 4.0), using {{Art Photo}} template

Media with difficult-to-copy-paste filenames[edit]

Strings in right-to-left languages are notoriously difficult to copy/paste, on desktop and even more on mobile. Note that switching to Wikidata-like identifiers instead of filenames would solve the problem.

  • قط بري

  • אדם סנדרסון

  • පනාවිටිය අම්බලම

  • ফুলের নাম-ঝুনঝুনি

Photos and scans of two-dimensional artworks[edit]

  • A painting (with Wikidata item) depicting a few notable people (with Wikidata item) and approximately 15 other paintings (also with Wikidata item). The room itself is in a house in Amsterdam that also has a Wikidata item.

  • A painting with many 'formerly attributed to' values (via PKM)

  • Photograph using {{Photograph}} template with great many translations of the description and separate information about the history and provenance of two books it was published in. Also image annotations. (via Jarekt)

  • image of a map published in a book. The image should be using data from {{Map}} and {{Book}} infoboxes. (via Jarekt)

  • Photograph of a mural depicting Michelangelo's Moses. So potential for at least 3 main authors that might need to be attributed (via Jarekt)

  • A photograph sourced with a {{Cite web}} template, which would also benefit from being converted to structured data.

  • Separate PD-old licenses for the painter and the photographer

  • Official portrait of Gojong, 26th king of Joseon. Using {{Artwork}} template. PD-old for portrait, and KOGL for photography. (via revi)

  • Drawing of Kim Hong-do, people learning and teaching archery. Using {{Artwork}} template. (via revi)

  • This glass painting may represent the kings Aurelius Ambrosius and Arthur, but we are not really sure.

  • File with attribution template and {{Artwork}} template containing multiple image-specific external links

  • Title page of a 17th-century book. We also have categories for general book covers, half titles, frontispieces, edition notice pages, dedication pages, endpapers etc. In this case the portrait engraving has an item in its own right (Q126172); most engravings do not.

  • Image from a 13th-century manuscript

  • 19th-century re-drawn illustration of 13th-century manuscript image

  • 19th-century book illustration, re-drawn from a detail of a 17th-century map in a well-known atlas

  • 17th-century self-portrait engraving

  • A different 'state' of the engraving (eg the shield below is different). Commons has images for 7 different such contemporary variants for this engraving.

  • 19th-century book engraving after a watercolour created for the book.

  • 19th-century engraving from a book of engravings from drawings by one particular artist (with whom the engravings are most associated).

  • 19th-century book engraving from a book by one particular engraver (with whom the engravings are most associated), from preliminary drawings by different draughtsmen. Image tone has been possibly over-readjusted, post initial upload.

  • 1824 engraving based on now-destroyed original said to have been by (or possibly close copy after) Hans Holbein

  • 1869 re-engraving, based on the previous

  • 1882 book illustration apparently inspired by the previous

  • We have this down as painted by Cephas Giovanni Thompson (1809-1888). Not clear what its exact relationship may have been to any of the previous. In addition, versions were also painted by J.G. Chapman (1808-1889), of which [1] and [2] may be representations.

  • Watercolour by Turner

  • Aquatint engraving inspired by the Turner; not as exact a copy as some of the other engravings above.

  • 20th-century forgery after 17th-century original

  • 20th-century forgery after the style of 17th-century painter (but not reproducing a direct original)

  • Faithful reproduction of CC-BY-SA licensed art work (it seems we don't have a template for this case now)

  • A work of art with 2 authors with different functions, which should be specified

Others[edit]

  • Solargraph Date: 15 October to 26 December 2009.
    Structured data fails to save the date information for this image. It fails if any field requires unusual or unanticipated content. This is a serious defect compared to current capabilities. It must be possible to special-case any structured field to accept free text, to deal with unusual or novel situations.

  • I can distinguish hundreds of Wikidata-worthy structures "depicted" in this highly-detailed satellite picture.

  • What location for this satellite picture?

  • This boiler was made in Wolverhampton and is now used in Bangladesh. What is the relationship between this picture and Wolverhampton?

  • "The embassy is not here anymore" notice. What is the relationship between this picture and the embassy?

  • Sign at the entrance of the "Japan Lime Association", which does not have a Wikidata item. What is the relationship between this picture and lime?

  • An opaque closed container that contains a substance (which is thus invisible and of a different color), intended in this case for a more specific field (an antibiotic as a veterinary drug).

Photos of three-dimensional artworks[edit]

  • Photo of a 3D copyrighted sculpture in public space, falls under Freedom of Panorama in Switzerland (via Yann)

  • Metadata is more about the photo than the depicted object (author is the Museum, not the fashion designer). (Via PKM)

  • Item with extremely long and detailed description provided by the collection, requiring specialist vocabulary to translate. (Via PKM)

  • The item is a utilitarian object (an ornamental craft) and doesn't fall under copyright in the US.

  • File with named sculptor and photographer. OTRS from photographer. (Via Jarekt)

  • Another sculpture using {{Art Photo}} template to add info about artwork and the photographer.

  • {{Art Photo}} doesn't really work for this file with 3 layers of copyright & authors: 1) original 18th century statue – out of copyright now. 2) 2012 bronze reproduction – Freedom of Panorama in Germany. 3) Photograph – CC-0

  • Some say this archaeological artifact depicts a human, but some may see a plant.

  • Conceptual art, emptiness is what makes "this" interesting.

  • This picture does not really depict the Old St. Louis County Courthouse, it was taken to show exposure bracketing.

Graphics[edit]

  • Simple album cover, ineligible for copyright (via Yann)

  • Graphic released under a free license by a Commons contributor, available only in English (via Yann)

  • Graph that can be used to explain various things about ellipses. It is rather language-neutral.

  • A logo containing another logo

  • Animated SVG (does not work on all browsers)

  • Example image (literally a placeholder) in German

  • "Magic eye" image, not quite 3D.

  • regularly updated time series data

A PNG file can be fix or with moving parts --Rical (talk) 10:23, 19 December 2017 (UTC)

Digitized 78 RPM record as lossless Flac file. MediaWiki can still not read the tags embedded in the Flac file (It can read the same tags from lossy Ogg files). This file is using the {{Musical work}} template but most information that could be structured data is just in the free text description field. The original source provides each field as semantic properties.

Maps[edit]

Maps use the template Map. It displays similar properties as the Artwork template, with added information from other templates. Additionally, the bounding box or the centroid of the map can be described with coordinates. The Map template displays a link to Wikimaps Warper, where it is possible to georectify the map and align it with a base map. If the map has been rectified with the Warper, the Map template knows it. The properties used in the Map template have been listed and mapped to Wikidata properties in the Wikidata WikiProject Maps: Historical map properties page.

  • Uganda Railway. Mombasa to Port Florence, 1909 – British Library War Office Archives

  • A historic map, part of a coastal survey undertaken by NOAA from 1835-1845, focusing on the New Jersey Coast area. It was used in a research project to map shoreline changes.

  • Large notes on disputed borders between India, Pakistan and China; Complex Map legend in Map template, Several sources for information used in map but map is Own Work.

  • The map sheet is part of an atlas, that has been gathered in the enclosing category. The category can be imported to Wikimaps Warper in a single import for georectification (see the mosaic). This is an admin feature in the Wikimaps Warper.

Complex cases[edit]

Categories[edit]

  • Category:Louvre G 133 the artwork in itself depicts lot of stuff ; each individual pictures depicts just a part of that

Data[edit]

(random picks; there may be better examples)

Going beyond the metadata of such files (including the real-world meaning of different columns), would a SERVICE be possible to access the actual contents of one of these files from a query?
