Proposing linked data tagging scheme:
JOSM gives you the power to do OpenHistoricalMap mapping offline, use custom filters, use custom base maps without tools like Map Warper and much more.
I could not find any used solution for marking up information as hypothetical so I did it in my own way.
For dates OHM seams to use
end_date(that's at least what I have been seeing).
So when I decided on how I would mark up hypothetical information I wanted to be flexible.
I started with
ohm:hypothetical, then follows the tag/key that's hypothetical. for example a hypothetical
start_date would look like:
ohm:hypothetical:start_date=yes this would also allow the value to be
no for none hypothetical information.
The reason not to use
ohm:hypothetical=<tag-name>" is that then you can't have more then one
ohm:hypothetical tag(OSM does not allow duplicate keys).
For marking up a hypothetical location I can see two approaches one is to just have
ohm:hypothetical:ohm:location=yes another is go with
Another approach to the problem would be to just append the hypothetical key with
If it does exist a common solution I can replace my one, but I could not find one...
Anyone else that have been marking up any data as hypothetical? How did you do this?
Feedback on this?
end_date should they be
ohm:end_date? They are OHM specific as far as I know.
