Explanation of the column names
- Date: The date on which the report was generated.
- Full institution name: The full/official name of the institution
- Example: Universiteitsbibliotheek Leiden
- Commons category: The main category on Wikimedia Commons containing the images related to the (collections of the) institution.
- Example: Collections of Leiden University Library
- Commons category URL: The full URL of this category, with spaces replaced by underscores.
- Category depth: The level of subcategories that are taken into account for the report. This is an input paramater of the GLAMorous tool.
- Examples: 0 (no subcategories, only images in the main category are used), 1 (all first level subcategories) etc.
- Total images available: The total number of images available in the main category and its tree of subcategories (as specified by the category depth).
- Distinct images used: The unique/distinct number of images from this category tree that are used in Wikipedia articles (all language versions).
- Image reuse percentage: The percentage of the available images that are actually used in Wikipedia articles. This is a measure for the uptake of the images.
- Example: (3.397/194.097) * 100 = 1.75%
- Distinct articles: The number of unique/distinct Wikipedia articles (all language versions) that are illustrated by (one or more) images from the category tree.
- Number of languages: The number of Wikipedia language versions in which images from the category tree are used.
- Total usages: The total number of times that images from the category tree show up in Wikipedia articles, in all language versions. This is different from ‘Distinct articles’, as a single image can illustrate multiple articles and v.v, one article can contain multiple images. For illustration, see this easy example.
- Average image reuse: The average number of times a single image is used to illustrate an article. This is ‘Total usages’ divided by ‘Distinct images used’. This is a measure for the outreach effectiveness of the images that are used in Wikipedia articles. For example, if we look at the Wereldmuseum Rotterdam, we see that only 3 of their images show up in articles 79 times, resulting in an average image reuse of 79/3 = 26.33. These couple of images are very effective in their reach and are seen worldwide! At the other end of the spectrum is the Rijksdienst voor het Cultureel Erfgoed; their 23.471 distinct images ‘only’ have 31.955 usages, making this number equal 1.36.
- Example: 8.288/3.397 = 2.44
- HTML URL: URL of the report for the specified date (04-09-2024)
- Excel URL: URL of the corresponding Excel file of the specified date (04-09-2024). This file shows which exact images are used per article.
