We've previously talked about 'locking' some key/value pairs in certain applications for specific purposes, such as historic:era=RomanRepublic for tools that focus exclusively on that period. I don't think that this is particularly controversial since it allows different audiences to work with the same backend without too much hand-holding on the details.<br></div>
<div> </div>
<div>
CRM-CIDOC is sometimes suggested as a meta-data standard for historical geodata, but it needs some maturing before it becomes operationally useful. The Open Geospatial Consortium has a number of different specs that are of interest, including GML. A redux of some of those ideas exist in GeoSparql at OpenGIS.net, with the most important being the separation between the feature and the geometry. OSM does not currently differentiate between the two and this is a problem for us since we can't differentiate between a conflict over a feature (which Cartage?) and its location (Where was Cartage?).<br></div>
<div> </div>
<div>
Something that GML has made an attempt at recording and that remains poorly used in OSM is precision and/or accuracy. There is a difference between a county border as traced from a 1900 digitized 1:80,000 map and a ww1 era fortification whose location is fixed using a GPS.<br></div>
<div> </div>
<div>
We've similarly discussed temporal issues on the list before; I would push for a two level solution that mixes both era's and XMLSchema-style dates. This allows for the use of well-known era tags 'ww1' while anchoring them in specific datetimes. Time OWL already supports this and the Open Geospatial Consortium is also heading in this direction with their own upcoming recommendations.<br></div>
<div> </div>
<div>
One thing we need to communicate well in the proposal: this isn't about rendering a nice map with a time slider but about managing the data underneath that drives the visualization. Not all reviewers will immediately understand the difference and we have to highlight it.<br></div>
<div> </div>
<div>
Quick question: does anyone see a massive need to support something else that WGS84 in the immediate future?<br></div>
