font-family: 'Times New Roman'; "><span style="font-family: 'Times New Roman'; "><span class="Apple-tab-span" style="white-space:pre"> </span>Question for anyone who's looked at this closely is how tightly linked into OSM.org should this be. As is, you can easily specify time delimited tags (start_date=*, end_date=*), but the OSM tool chain does not have in-built awareness for them. For an example of the problem, here's the situation for multiple years of Burning Man (http://osm.org/go/Tc4Ki1bp-). Should OSM.org itself become time-aware, or rather, should OSM.org continue to represent only the "present moment"? No matter the answer, there's one good and feasible approach here to the broader question, and in any case, OHM will benefit.</span><br></div><div style="color: rgb(0, 0, 0); font-size: 16px; font-family: 'times new roman', 'new york', times, serif; background-color: transparent; font-style: normal; "><br></div><div style="color: rgb(0, 0, 0);
