>From the thread it appears OSM is not the culprit of bad data, at least in many cases. Nonetheless it certainly makes sense thinking about data accuracy. I am not aware of a widespread organized system of making sure OSM data is up to date.
We know the time of the last change to a feature. It might be a good idea to have a way of stating a feature remains valid (and placing a time stamp on it). The easiest thing to do would be add a tag like "validated":"YYYY:MM:DD". There could also be a web map that loads an area of data and lets a user mark the features as valid or label them for fixing (at which point an editor could open or a marker tag could be set). When a feature is overdue to be validated, it can be highlighted on the map so the user knows it should be checked. Features of different types have different lifetimes. Businesses can change very often, whereas something like the ocean is less likely to change month to month (well, in a way significant for mapping). Different feature types can given different timeouts before they are flagged as overdue of validation. This is not a complete solution. It would also be nice to be able to validate the absence of something. Suggestions? At the very least, this would give mappers something to do once their local area runs out of necessary edits.
