This has often cropped up in conversation but we never put the time into actually adding the vocabulary. I suggest we add a type for PublicToilet as it addresses a fundamental and universal truth of human experience.

Also specifically I would like to use it for two case studies:

• Accessibility of places #254 - physical accessibility of places. We have discussed this before but got stuck on details/scope.
• Show how to use W3C CSVW rdf mappings to extract Schema.org from CSVs #1623 - mapping of tabular data into schema.org descriptions. There are various efforts to make available datasets describing public toilets, their locations and other properties, typically using tabular data.

Proposed definition

• The English Wikipedia says "A public toilet is a room or small building containing one or more toilets (and possibly also urinals) which is available for use by the general public, or by customers or employees of certain businesses."; this seems reasonable (Wikidata:
  Q813966).
• supertype would be CivicStructure, i.e. a kind of Place.
• We should show how to apply existing vocabulary for opening hours, locations, constraints on intended users including gender. Again from Wikipedia, "Public toilets are commonly separated into male and female facilities, although some can be unisex, particularly the smaller or single-occupancy types. Increasingly, public toilets are accessible to people with disabilities.".
• We should examing open data datasets and try to match as much of their expressivity as possible. This can be explored via W3C CSVW mappings, per Show how to use W3C CSVW rdf mappings to extract Schema.org from CSVs #1623.

Sample datasets

UK, thanks to GDS for details

From a UK initiative in which various datasets (including public toilets data) were published by local authorities (exploratory / non-mandatory so only partial coverage).

• UK PublicToilets schema documentation including pdf overview and github.
• The published toilets data to this schema by participating councils is available on data.gov.uk and on the LGA’s open data resources pages.
• An aggregation tool is also available

• this creates a csv of all the data published to the schema (see the link at the bottom of the page in the previous link).

• The Great British Toilet Map (generated from this data)
