Property needed to add archived version of many pages when they are down. Very bright future I suppose for this property as servers cannot be maintained forever so sites go down and can be linked through Wayback when needed. Obsuser (talk) 03:05, 16 July 2019 (UTC)


  • Symbol oppose vote.svg Oppose; archive URL (P1065) already exists, and full work available at (P953) could also be used. A copy of Facebook's home page is also not a sufficient substitute for the actual Facebook website, so I don't think the example would be an appropriate use of this hypothetical property.

    archive URL (P1065) and full work available at (P953) can hypothetically be used to link Discogs too, for example, and we have separated properties however. It's not copy, it's page source of original with no alteration (it's arhived original). --Obsuser (talk) 10:44, 16 July 2019 (UTC)
    @Obsuser: It's sort of pointless to make this an identifier, though, since anyone can save a page that's currently online to the Wayback Machine, and there could be dozens to thousands of duplicates for each work. Given that we would normally be obligated to add as many valid identifiers as possible, you could keep adding valid identifiers indefinitely just by saving news articles every hour. I don't think this would be useful data.
    Maybe you could argue for splitting archive URL (P1065) into a few different properties for each archival service, but it would break anything that already uses the existing property for what would essentially be a cosmetic change, and you could use a few lines of Lua code to separate archive URL (P1065) values by the archival service used if that were ever needed in a Wikipedia template.
