Proposed Features/Life cycle relation
|Life cycle relation|
|Status:||Draft (under way)|
|Definition:||defines features that are not yet or no longer in use|
|Rendered as:||depends on relation members and life_cycle, see also #Values for life_cycle|
A life_cycle relation can be used to map a feature that is not yet or no longer in use. The tags describing the feature are added to a relation, together with a tag describing the life cycle status and optionally information about begin and end dates of life cycle state.
Features under construction and disused objects in various states of decay are common and usually mapworthy – while they cannot be used for their intended/original purpose, they still serve as visible landmarks or may be of historical interest. It is common for maps to include this type of information.
|life_cycle||construction / disused||required||see #Values for life_cycle|
|life_cycle:start_date||date in YYYY-MM-DD format||optional||when the life cycle state described by this relation started / will start|
|life_cycle:end_date||date in YYYY-MM-DD format||optional||when the life cycle state described by this relation ended / will end|
|*||*||required||other tags actually describing the feature|
|at least one||location of the feature under construction / disused feature|
Values for life_cycle
The following values are possible for the life_cycle key. There are other suggestions, such as
planned – these can be easily added later, but are not part of this proposal, which is likely controversial enough itself.
