discontinued date date that the availability of a product or service was discontinued; see also "dissolved, abolished or demolished" (P576) and "service retirement" (P730) for pieces or classes of equipment
any commercial product whose availability is limited over time, such as computer hardware, proprietary computer software, individual models of motor vehicles or aircraft
(note: this should be moved to the property statements)
Per the property creation discussion: this is not a sub-property of end time (P582). In fact, that is the reason this property exists at all. P582 is about an item ceasing to exist. This is about the production run of a product ending, which does not mean it ceases to exist, which is what a sub-property would imply. Both properties are sub -properties of a theoretical property "date something ended", though. --Srittau (talk) 12:56, 27 March 2016 (UTC)[reply]
I was curious (inspired by seeing http://endoflife.date/ which is an open project, to which my first thought was maybe it could pull and/or push from wikidata) whether end of support (particualrly of security updates) are cataloged in wikidata, and it seems not, eg a well known case Ubuntu https://www.wikidata.org/wiki/Q381 notes that some releases are long term support (LTS) releases but not when support ends. So, I wonder whether this property should be used, or a new property might be useful? Mike Linksvayer (talk) 21:05, 13 November 2022 (UTC)[reply]
This is definitely not the correct property to use for that, as this represents the date the product was discontinued and products are usually supported for a time after discontinuation. I can't find any other properties that record this either, so I suggest proposing a new one, perhaps named "supported until". Thryduulf (talk) 11:00, 14 November 2022 (UTC)[reply]
