I've been reviewing the OSM tags with an eye to historic mapping, there have been quite a few tags proposed or used to give an object some temporal aspect: start_date, civilization and era. Some work is going to be required to get the renderer to handle these according to some user-tunable button but the basics are already in the openstreet map.
A suggestion is to take a page from the time ontology and adding the following tags: before and after. The reason for this is that it would ensure sanity when adding objects that occupy the same space in different times and would give the renderer a hint as to what to put on the screen instead of overlapping everything. It would also allow us to link the building as it was used with its ruins several hundred years later. Does anyone have any ideas about how to handle events that involve movement, such as forest fires or battlefields front lines? Jeff, when you happy with your server setup, I'd like to install the Sparqlify LOD bridge to the instance. It's the same software as LinkedGeoData. best, rhw [1] http://wiki.openstreetmap.org/wiki/Key:start_date [2] http://wiki.openstreetmap.org/wiki/Key:historic:civilization [3] http://wiki.openstreetmap.org/wiki/Key:historic:era [2] https://github.com/AKSW/Sparqlify/ _______________________________________________ Historic mailing list [email protected] http://lists.openstreetmap.org/listinfo/historic
