In https://github.com/wikimedia/restbase/pull/311 we noticed that our current content specs aren't as consistent as they could be. Some are linking to non-existing urls like mediawiki.org/specs/data-parsoid/0.0.1, while others are using https://mediawiki.org or just mw.org.
I would like to propose linking to actual wiki pages documenting the spec instead. An example would be the content of https://www.mediawiki.org/wiki/Parsoid/MediaWiki_DOM_spec snapshotted at a url like https://mediawiki.org/wiki/specs/html/1.0.0. Updating the spec would entail creating a new subpage. There could be a changelog in there somewhere as well.
By using wiki pages, we can link to actually useful information, and lower the bar for spec improvements. We will have to watch those spaces to avoid the information becoming inaccurate. If bad edits become a problem (unlikely), then we could still protect those pages.
@cscott, @ssastry, @mobrovac, @Eevans, @Arlolra, @Pchelolo: Does this sound like a useful direction to you?
