==Local Conventions==
In 2009, we began a convention with parks, starting with [[user:Apo42]]'s tagging of State Park data that included {{Tag|park:type|state_park}}. In Santa Cruz County (and elsewhere afterwards), this was extended to include {{Tag|park:type|county_park}} and {{Tag|park:type|city_park}} for parks with management/jurisdiction at those admin_levels (there were explorations to combine these tags with {{key|admin_level||}} at some point) and {{Tag|park:type|private_park}} to private parks (for example, a small decathlon-event park with {{key|access||private}}), private campgrounds and for-fee short-term trailer parks. The point was not to make these render (yet) but such tags are useful in a search query, for example. A proto-proposal ({{tag|park_level}}, see {{Tag|park:type}}) to combine these tags with {{key|boundary||}} so these render with different color dashing was developed but never more widely submitted to the OSM community; the plan was for rendering to be extended to display parks tagged with state_park, county_park, city_park and private_park using different colors of dashing. (TodayIn later versions of mapnik, {{key|boundary||national_park}} renders in mapnik with green dashes, and it was a partially accepted OSM convention that this tag was appropriate on state parks, though this now appears to be discouraged). See [https://wiki.osm.org/wiki/Talk:Key:park:type this] Discussion, which offers a proposal to deprecate {{Tag|park:type}} in preference of more modern, widely accepted and better documented park tagging standards. Included is the newer tagging scheme of {{key|boundary||protected_area}}, utilizing {{key|protection_title||}} and {{key|protect_class||}} keys (themselves not well-developed regarding rendering) which may be applicable to some remaining park-like areas now denoted {{tag|leisure|park}} (especially "undeveloped parks" owned by a city or county park agency). Progress on this transition has already begun here, for example [http://www.osm.org/way/686353436 this] used to be tagged {{tag|leisure|park}}, but is now more accurately tagged {{tag|boundary|protected_area}}. A distinct trend has emerged to actively deprecate {{Tag|park:type}}: especially with the {{Tag|park:type|city_park}} value, simply change this to {{Tag|ownership|municipal}}.
 
As noted in the [[Santa_Cruz_County,_California/Archive]], because the county is 2/3 wooded, many {{tag|landuse|special_use}} polygons from early SCCGIS imports were tagged {{tag|natural|wood}}. This tag is NOT used "usually" at UCSC, so the campus renders with its preferred light-yellow {{tag|amenity|university}} tag. Being simultaneously a university yet also heavily wooded with redwood trees, local OSM convention assumes UCSC is "already" wooded, "except where it is not." For contrast, the Campus Natural Reserve polygons ARE explicitly set to {{tag|natural|wood}} and Lower Moore Creek and Cave Gulch/Wilder even have some {{tag|landuse|meadow}} on top of these, plus there are woods at the Arboretum. So, UCSC's {{tag|amenity|university}} polygon is "assumed to be wooded, unless tagged otherwise" — such as {{tag|natural|grassland}} (grassy areas not grazed by cattle), {{tag|landuse|meadow}} (grassy areas which ''are'' grazed by cattle), {{tag|amenity|parking}}, {{tag|building|university}}, {{tag|building|dormitory}}, {{tag|highway}}, etc.
