|Status:||Proposed (under way)|
|Definition:||A way to group features which belong together but cannot be adequately described by an area/multipolygon.|
A way to group features (represented by nodes/ways/areas/relations) which belong together but cannot be adequately described by an area/multipolygon. A common example of this is a university site with a number of separate buildings across the city. This relation is understood to group man-made objects. For groups of natural objects which share the same name see Cluster.
However, this relation is not to be used in cases where the elements are inside one or more areas where the perimeter can be tagged with an appropriate area tag. For example the tag amenity=school describes the perimeter of the school grounds, for schools with multiple sites the multipolygon relation can be used. Usage of a site relation is not appropriate here.
The features should have a close geographic relationship, usually within the same town. For example do not use this relation to group all restaurants of a fast-food chain. Use a a combination of name=*/operator=*/network=* to group loosely coupled and/or widely distributed features - relations are not categories!
|*||*||The main tag - whatever feature the site relation describes. E.g. amenity=university, site=parking, power=plant.|
|name||*||The name of the feature|
|site||*||Legacy method of describing the type of the site, better use the full tag (see above).|
