Hi all,<br> As we all know, you don't "tag for the renderer". However, you want your map data to render nicely now, and you want correct map data in the long term.<br><br>Suggestion: introduce a "fallback" tag.<br>
<br>For example, around my city there are little "reserves" - patches of grass reserved by the government for future development such as freeways or train lines. They often get tagged "leisure=park", but say I want to start tagging them "landuse=reserve" instead. Suddenly, instead of being green on mapnik, it will be white again - unrecognised tag.<br>
<br>Solution: tag it like this:<br>landuse=reserve<br>fallback:leisure=park<br><br>That's pretty simple logic to explain to any renderer or editor, and it gives people a way to avoid the temptation of "tagging for the renderer", and allows them to tag for the future instead.<br>
<br>What do people think? (No comments on how to tag land reserves, it's just an example...)<br><br>(This case is slightly complicated by the fact that the two tags - landuse and leisure - are different. Perhaps a more explicit fallback:landuse=leisure:park would be clearer.)<br>
