<div dir="ltr">I use survey:date to record survey checks of some features interesting for hiking: routes, benches, Network Nodes. Check_date is too broad for me, I want to know when the feature was actually seen, while check could be that a data source was checked. In my case, that is very unreliable.<div><br></div><div>Same issue though: it confirms the thing actually existed on that date, but does it (additionally) mean that all the attributes were correct? I use the same question in the MapComplete tool: Does it still exist? If yes, questions about important attributes are asked but they can be skipped. If no, the disused: lifecycle prefix (and a note) is set on the defining tags, awaiting removal.</div><div><br></div><div>So the result is that you can't be sure that all the attributes were correct on the survey:date.</div><div><br></div><div>I now realise that can be an issue, but I cannot think of a workable alternative. In my area of interest this is not a problem, but it is not a generally applicable method, because many features have tags that you cannot verify on the ground, or you cannot reasonably expect all mappers to know enough to verify it, while you still want to know what they can manage to verify. </div><div><br></div><div>I can't see all mappers to set check- or survey (verification) dates for separate tags. So I think this kind of thing usually is part of a maintenance workflow or scheme, which means there will be some kind of understanding (and tooling) between the maintainers. </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Op di 3 aug. 2021 om 14:46 schreef Mateusz Konieczny via Tagging <<a href="mailto:tagging@openstreetmap.org">tagging@openstreetmap.org</a>>:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

However, the wiki entry<br></div><div>for check_date=* [1] says:<br></div><blockquote>Date of latest review of the data [...] The tag is intended to document the last date, when an object as a whole or specific tags of the object were checked and verified. [...] To indicate the review of specific tags the key is built from multiple words separated by colons like check_date:collection_times=* or check_date:opening_hours=*.

Besides, there is no other tag with the meaning<br></div><div>"everything last checked on" while there there are tags for "existence<br></div><div>last checked on" and adding the same number of check_date:<property><br></div><div>tags as a feature has tags seems impractical.<br></div><div><br></div><div>(For example, when used for a shop=* with opening_hours=* or an<br></div><div>amenity=post_box with collection_times=*, i expect<br></div><div>check_date=2021-07-31 to mean that it's opening hours or collection<br></div><div>times, respectively, have been last checked on 31 July 2021 too, not<br></div><div>only its existence, also because this information changes more often<br></div><div>than its existence.)<br></div><div><br></div><div>Therefore, i think that another tag should be used for the date on<br></div><div>which a feature was last checked for existence.
