Wikimedia Foundation GLAM team/Office Hours/April 2021

April 2021 meeting: Structured Data on CommonsEdit

There was a meeting on Monday, 26 April, 3.30 pm - 4.30 pm UTC, followed by another on Tuesday, 27 April, 11.00 am - 12.00 pm UTC.

On the first day, Carly Bogen, the Foundation's Program Manager for Structured Data, talked about the new Media Search and provided updates on the Structured Data Across Wikimedia project. Jennie Choi, General Manager of Collection Information for the Metropolitan Museum of Art, presented her process of batch uploading Structured Data on Commons.

On the second day, John Cummings, Wikimedian in Residence at UNESCO, and Alicia Fagerving, Developer at Wikimedia Sverige (WMSE), shared Wikimedia Sweden's plans with Structured Data, GLAM content, and Wiki Loves Monuments.




Carly Bogen

  • Carly presented Media Search, which uses Structured data on Commons metadata to enhance the search results.
    • Media Search also powers the visual editor on Wikipedia, allowing more image results, in more languages, to show up to illustrate Wikipedia articles.
    • To utilise these features, Carly recommended adding multiple depicts statements, both general and specific, to media files on Commons.
  • Work-in-progress: an assessment filter for Media Search, to surface files that have been assessed as quality or featured images.
  • Bot writers in the Cebuano and Arabic communities are experimenting with the Image Suggestion API to test the feasibility of adding images to Wikipedia automatically.
  • Carly shared early concepts for how Upload Wizard could prompt contributors to add both general and specific depicts; how image suggestions could be applied within page editing or VisualEditor flows; and how notifications could be used to suggest articles for images that have just been uploaded, or suggest images for articles on watchlists.
  • Discussion: balancing automated suggestions with respect for the experience of on-wiki “lived consensus” and some participants suggested an “opt-out” flag for certain pages to be excluded.

Jennie Choi

Lecture about the Structured Data on Commons uploads by the Metropolitan Museum of Art using M-IDs, PetScan, and QuickStatements
  • Jennie shared how she has added more than 10,000 Structured data statements to the Metropolitan Museum of Art files on Commons.
  • Her objective is to improve the use of the institution’s images on Wikipedia, after learning that only 6% of their images have been used on Wikimedia projects. This would improve the already high number of views the MET receives.
  • Jennie used the PetScan to get the images' M-IDs (process described here), followed by the QuickStatements (described here).
  • Discussion: Structured data on Commons modeling and the differences between metadata on Commons and Wikidata.

John Cummings

  • John is working at Wikimedia Sweden to share guidelines related to Structured data on Commons and GLAMs.
  • His presentation was an introduction to how both Wikidata and Commons can make content from institutions more searchable, especially with Structured data on Commons properties, such as depicts, creator, source of file, rights statements, location, multilingual captions, and so on.
  • Discussion: the need to find agreement on data modeling and share example queries.

Alicia Fagerving

  • Alicia presented some use cases with the Structured data on Commons uploads for Wiki Loves Monuments in Sweden, Israel, and Poland.
  • Bots have already added statements like creator, inception, and coordinates of point of view.
  • Alicia has added depicts statements to make images more searchable and participant in statements to allow new analysis.
  • Discussion: interest from other attendees in applying this approach to other contexts and a discussion about the use of participant in versus on focus list of Wikimedia project.
