A lot of this kind of information (like public toilets) is not really suitable for fixed schemas and periodic release. It works better as a log of simple events that relate to a particular thing in the real world.<p>For example:<p>* Disabled toilet opened (01/01/2012).
* Reports of graffiti from member of public (06/02/2012).
* Opening hours changed to 8am - 8pm (14/02/2013).<p>The flow of events contain much more information than a few edited facts. It allows people to enter complete information without needing to agree a schema. The data on its own is useful without complex tools or UI.
