The OSM Wiki does have a {{cite map}} template, but it’s based on an extremely old version of an English Wikipedia template (documentation). Someone needs to completely revamp the wiki’s collection of citation templates, upgrading to the CS1 citation module or the Wikimedia Commons version, which may be better suited to a multilingual wiki. Modern citation templates would also enable us to maintain bibliographies on the wiki instead of trying to stuff them into 255-character-long tags.
