The main reason that I am wanting mapping information is exactly because I am looking at genealogical data and this most definitely requires that start and end dates are accurately recorded. In many areas of the world historic map information may well not be available, but in the UK we have some reasonably accurate material going back 3 or 4 hundred years in places. More speculative material such as ancient Rome or Greece may be a little more controversial, but even that has some will mapped archaeology which it would also be nice to preserve.<br>
<br></blockquote><div><br>I think it's really a question for the foundation:<br>- is OSM a database for the present only or not ? <br>- If not, is it the job of the API to filter data by dates or is it something to be filtered by (all) OSM editors ? <br>
Because most of the contributors don't want to see historical data (which they don't care/cannot verify) mixed with the today's data in their editor.<br></div></div>And without going back to the ancient Rome, every day some OSM data become obsolete (shops dissapearing, builings/roads destroyed, etc) and the average contributor will just delete them and not just add a tag 'end_date'.<br>
