Hi! I wonder if I’m on the right track?
I’ve created boundaries for parishes in Stockholm county. The ambition has been to capture all changes. Every change means that a new parish is created. So far their names are separated by the addition of years to their names. Waiting for the time slider the boundaries are all piled on one another.
I began using start_date and end_date but saw this edit. Using the date namespace solves some problems whict start and end_date can’t cope with.
In most cases I have given some source. It looks like this. The handling of sources is another question which should be carefully considered. I have used a great number of maps for my edits, in most cases just to make sure that I have not missed something. Few edits are based on a specific map and most edits are also based on text sources, normally the SCB censuses or corresponding Stockholm municipality statistics. The geometries are, if possible, taken from the dataset made available by Valmyndigheten, if a geometry is missing there, my second hand choice is a trace of Ekonomiska kartan. They can also be taken from other maps.
The most important sources are:
Valmyndigheten, valdistrikt
SCB censuses
Stockholms statistiska årsbok, both maps and info about changes.
Lantmäteriet, kronologiska and alfabetiska registret from “Historiska kartor”
Lantmäteriet, whathever relevant maps are available
I have asked Lantmäteriet for permission to use Valmyndigheten’s data, and maps from “Historiska kartor” as sources. The permission is the OTRS ticket mentioned
I had some idea that the border markers should be geolocated with a gps-device and that tracing is a second best while waiting for someone to visit the place.
Nice, I was looking in the north of stockholm and didn’t see any sources/end_date in iD might have been my mistake. Probably an interface issue with iD or pebkac, because your relations for Botkyrka looks great. I still don’t like having the year in the name, but I can also see the value in that.
I understand your point, I guess everyone has to find their own way at this moment in time. I believe it’s probably easier to clone and remove stuff and use start/end on objects. The way of conditionalizing tags with years seems very hard to work with.
So the osm geomoetries and objects:
Election district 1 end_date=2013
Election district 2 end_date=2013
becomes the combined object:
Combined elections district start_date=2013
I’ll have to say again that this is a nice project.

I would use the tags start_date=YEAR end_date=YEAR and also source=* so we can know how you found this data.

But it’s very nice to see data for Stockholm, and I could gladly help tracing stuff if you have sources of data.
