Wikipedia 'Template Parameter Drift' in Infoboxes
This page measures how Wikipedia’s infobox templates decay as parameters become obsolete but remain in use. By analysing template revisions, it tracks the percentage of templates with deprecated parameters and the overall trend in their count. This reveals how structured data on Wikipedia evolves—or fails to—as editors adapt to changes in underlying templates. The data highlights gaps in maintenance and the challenges of keeping structured information up to date.
