Variations on the {{Information}} template

• 
  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
•

Media with difficult-to-copy-paste filenames

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

• 
  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)

  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.

  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

  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.

Others

• 
  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

• 
  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)

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

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

Maps

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.

  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

  Voynich Manuscript, page 178

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?

Interesting curation of media files

• Extensively, personally, customized, organized templates for images with high re-use value on high-traffic pages: https://commons.wikimedia.org/wiki/User:Evan-Amos
• Welsh Landscape Collection / Welsh Landscape Collection, by source -- for these engravings from books, each individual engraving has been given a separate Wikidata item, allowing interesting reports from Listeria.
• Self-portraits of Women, a gallery that is auto-generated from Wikidata.
