Talk:Requests for comment/Tagging within MediaWiki

Page properties, page tags, and so on
As far as how change tagging intersects with page properties, it doesn't. Anomie (talk) 15:14, 5 January 2015 (UTC)
 * Change tags are tags attached to a particular revision or log entry, intended for external use.
 * Page properties are parser data and other internal data about the page as it is currently parsed, generally so the page doesn't have to be parsed again to retrieve this information and so this information can be more directly queried.
 * Page tags, file tags, and so on sounds like something more along the lines of categories, just set up for use with tools for querying intersections ("'american' + 'female' + 'novelist'") rather than manually-curated hierarchies ("Category:American women novelists").
 * "Watchlist tags" sounds more like a possible implementation detail of the oft-requested multiple watchlists feature.
