I have yet to be convince!
But if there was a clean boilerplate for a place having all of the
various data fields the current manual blocks and categories links
currently include manually. I have raw data that is clear to use but
inputing it looks like a nightmare.

OSM includes a link for a place to wikipedia/wikidata
This then uses the storage in wikidata to manage abstract data such as
population figures and the like which vary over time. The problem part
is managing the changes of layout of structures on the ground over time.
New road layouts where the historic material is already mapped, while
simple new additions such as the new housing developments around here
just need a 'start_date' properly adding. Although the odd anoying
roundabout on a once straight road is a small element of history that
I'm going to need to map shortly ...

The vast majority of the material in wikipedia needs importing into
wikidata?
Then the wikipedia information blocks can be upgraded to the wikidata
content, and we get an easier update path.

You see my book that is even worse than XML schema data :( I see the
point but thousands of <Property:PXXX> entries to navigate?

We have a vast amount of the geo material already contained in OSM. It
is maintaining the historic changes to that which is the first problem.
Changes to political boundaries over the last several years are buried
in the OSM change log now and need recovering. Treating OHM in isolation
is simply wrong!

Need to earn a crust so I'll have to digest this next weekend ... should
be working now :)
