Proposal for a maps template
editBased on the discussion so far, the ideal way is to utilize Template:Artwork, Template:Book or Template:Information as a base and create a new Template:Map for the remaining necessary map data. It has now been created and it can be commented. Of the "base" templates the Book template seems to have most of the information that go along with printed maps. It is my intention that there will be wider discussion with GLAM representatives about what is sufficient metadata from their point of view. --Susannaanas (talk) 09:31, 9 July 2013 (UTC)
Proposed Map template to be used in addition to the Artwork template (comment, add, argue, describe)
editMap related fields
- Scale //added
- Projection //added
- Georeferencing data //not added
- Date depicted //not added
- Location depicted //not added
- Map type (town plan, tourism map, road map, thematic map, panorama, diagram, table...)
- Thematic map topic
- Manuscript/printed (Manuscript, original, duplicate, simple copy, certified copy, draft/concept, printed)
- Map sheet # / other sheets
- Material / technique (exists in artwork)
Note: Some necessary fields exist only in the Artwork template (material, size), others exist in the Book template (publisher, ISBN).

editSome thoughts on the location data
editFollowing are options for storing the location. There may be templates I have not yet discovered. Data to be stored seems clear: A bounding box is needed for the map boundaries (alternatively coordinates with diameter) for approximate geolocation. After georeferencing, the georeferencing data should be stored and the bounding box redefined for the purpose of finding the map in a map search.
Give a center coordinate
edit- Template:Coord, with additional info such as dim (diameter) and stretching
- Wikidata: m:Wikidata/Data_model#Geographic_locations
Bounding box (variations of expressing)
edit- Template:GeoPolygon

Wikimedia storage proposals
edit- Wikidata: OSM Object http://www.wikidata.org/wiki/Property:P402 Much debated, but still exists. Not useful for storing an element that does not have a physical correspondence, it would not be featured on the OSM map.
- Template:Attached_KML. There has been discussion that this option is causing trouble, so we should head for another one.

Georeferencing data
edit- sets of 4 numbers: Map image x, y, Coordinate lat, lon + additional data
