The scope of application of this proposal is limited to recognisable cemeteries as they are described in OSM: «places usually independent of place of worship» and «not close to a place of worship» (see {{Tag|landuse|cemetery}} for more details).

Proposal

This proposal tries to describe the value cemetery for the key historic=*, a value used to map historic cemeteries with the tag historic=cemetery in combination with landuse=cemetery.

The value is not a new value, mappers are already using it, but it is not yet documented on this wiki. The proposal aims to specify how to map a historic cemetery considering how the tag has been used so far.

The scope of application of this proposal is limited to recognisable cemeteries as they are described in OSM: «places usually independent of place of worship» and «not close to a place of worship». See landuse=cemetery for more details.

To know when a feature (e.g., a cemetery) has historic significance, see historic=*.

historic=cemetery:


Rationale

As of 8 February 2021 there were 1609 matches for the combination of tagging landuse=cemetery + historic=* in Taginfo. historic=cemetery has been used 475 times (445 on ways, 22 on nodes and 8 on relations), 405 uses in combination with landuse=cemetery, mainly in Europe (notably Poland and Germany). Also in North America (mainly the United States) and Australia.

This pattern of use suggests that mappers have used this tag as a complementary tag to landuse=cemetery to indicate that this feature is a historic cemetery. An alternative way for mapping a historic cemetery would be landuse=cemetery + historic=yes. This tagging has the disadvantage of being unspecific.

The historic=yes tag only is useful to add an unknown historical value to a given object, not to define the reason why objects have a historical value. Adding a descriptive attribute to the historic=* key is not redundant but adds new information. It is a totally different category than simply describing the object as a cemetery.

The value in the tag historic=* is used to characterise the type of feature (see Use). This value should be widely recognised and are in common use. The historic=cemetery tagging is a better alternative to historic=yes in this case. The value cemetery for a historic cemetery is very recognisable and commonly used in the real world to refer to a cemetery with historic significance.

Be included on an authoritative listing of historic sites or a special protected status could be considered as supporting evidence that a cemetery is sufficiently significant. However, being included on an authoritative listing of historic sites is not a mandatory requirement for mapping a historic cemetery in OSM. Factors to consider when tagging a cemetery as historic=cemetery are listed in historic=*. The inclusion of a historic cemetery in an authoritative listing of historic sites can be indicated using heritage=*.

Some historic cemeteries continue to operate as cemeteries for new burials. Others may have stopped accepting new burials and are preserved only as a historical site. A cemetery preserved as a historic site remains a cemetery. Life cycle prefixes could be used where appropriate.

Tagging

Only one new tag is proposed. Actually, a value in use but not documented for historic=*:

The database elements where this tag could be used are nodes node and areas area, the same elements that are used for landuse=cemetery.

It could also be used as relation (issue to be discussed).

Examples

Rendering

The rendering for a historic cemetery on the standard tile layer could be the same rendering used for landuse=cemetery but in the colour tone used for historical features.

Features/Pages affected

No features would be affected.

The following pages may need some modification/addiction if this tagging is approved:

External discussions

  • A discussion thread on the Tagging mailing list about the same feature before this proposal (2020-12-02).
  • A discussion thread on the Tagging mailing list to ask for suggestions for the draft of this proposal (2021-02-09).
  • Association of Significant Cemeteries of Europe (ASCE), a not-for-profit organisation which care for cemeteries considered to be of historical or artistic importance. The ASCE website includes a map with more than 150 significant cemeteries across Europe. All these cemeteries are probably candidates to be mapped on OSM as historic=cemetery only in Europe.
