We have been trying to fit substantially more information into the OSM tagging schema than it was originally meant to support. Workarounds are available for simple things with start_date and end_date, but we can only go so far with things like 'DisusedRailroad'.<br>
<br>
>From other work, the recording of historical GIS data requires:<br>
<br>
a) Labelling by language, datetime and by source. The 'source' is necessary to keep sanity when dealing with multiple nomenclatures used by different people.<br>
b) The associated feature by datetime.<br>
c) The different geometries associated to the features by datetime.<br>
d) The different states (active, disused, abandoned, damaged) by datetime.<br>
<br>
The above is the only way to capture all of the use cases you mention. Given the amount of work that an NEH submission is going to be, perhaps we should look at a redesign of what is under the hood. OSM is already using two different databases for editing and rendering!<br>
