[OHM] TimeSlider - calling attention to early prototype

Wed May 14 12:07:03 UTC 2014

Certainly my main concern at the moment is a slider for allocating a
suitable active date range to an object in an editor, and my comments have
been from that perspective.

I would agree that for consumption of data a single time point selector is
needed: I presume that simply dropping one of the end points on the demo
sliders would achieve that at a technical level.

Two other comments:

   - I think some of the early use cases for OHM were for mapping military
   campaigns (and specifically WWI battlefields) in which case day level
   granularity is needed on the sliders.
   - I realise I'm not clear about where we propose to store event related
   location data (for instance, locations of ships in a sea battle, such as
   Jutland/Skaggerak). This type of truly ephemeral data does not fit
   particularly well with the OSM-derived model.
