Proposal:Planted date unification
| Planted date unification | |
|---|---|
| Proposal status: | Draft (under way) |
| Proposed by: | UsefulRabbit |
| Draft started: | 2024-07-13 |
Proposal
Establish that start_date=* is the primary way of tagging the date when vegetation was planted in its current location (or otherwise came into existence).
Deprecate the following tags, encouraging usage of start_date=* instead as a drop-in replacement:
- planted_date=*
- planted=*
- date_planted=*
- date:planted=*
- year_planted=*
- plant_year=*
Deprecate the planted:age=* tag, encouraging concrete years/months/days with start_date=*, and the tree's size with age=*.
Further consensus is needed on age=*.
Rationale
Currently, we use a variety of tags to indicate when a plant was planted. This is undesirable for people who want to query or display that information in a unified manner.
start_date=* is the most-used tag for indicating planted dates on OSM (427,464 at the time of writing) and has applications outside of mapping plants, so I selected it to be the primary tag.
Statistics for tags that will be deprecated are linked below.
| Tag | Count |
|---|---|
| planted_date=* | |
| planted=* | |
| year_planted=* | |
| date:planted=* | |
| date_planted=* | |
| plant_year=* | |
| plant:age=* |
Tagging
Use the established conventions used with start_date=*.
Examples
Here are a handful of examples correctly using start_date=* for planted dates:
- node 11036039567 (named significant historical tree)
- node 9543825822 (named significant local tree)
- node 3707416388 (unnamed ordinary tree)
Rendering
Not necessarily relevant.
Features/Pages affected
- Add a section to start_date=* explaining the new convention.
- Mark planted_date=* as deprecated.
- Create the following pages as redirects to one of the above pages. Redirect them to a section explaining the deprecation:
- planted=*
- date:planted=*
- planted_date=*
- year_planted=*
- plant_date=*
- plant:age=* - This one is a bit special, considering the additional existence of age=*.
