How about if I summarize the discussion so far, and see if there is misunderstanding: *One)* We have a "fixme" system where human mappers are encouraged to pay extra attention to particular areas or objects. *Two) *There is an issue of mapper fatigue: each mapper will look at only so many such tags in a lifetime of mapping. *Three)* The fixme system is not self-cleaning. Certain conditions result in fixme tags that are unlikely to be acted on. There are some 1.3 million open fixme tagged items, more than half from mechanical tagging. *Four)* In some cases the fixme tags happen to be associated with poor quality imports. But this is not universal: some poor data has fixme tags, other poor data does not. Similarly some mechanically added fixme tags are valuable, some are (ahem) less so. ------------------------------------------------------------- How about a two step process: *Step One ) * People who wish to delete a particular import look through the FIXME tagged items, and propose specific deletions. For example there's a bus stop import that looks to be of bad quality. If that data is removed, the fixme tag will go with it. Problem solved. *Make a specific proposal showing why the fixme tag is needed in order to clean the data.* *Step Two ) *Remaining fixme values with a count above 10000 are reviewed. If they are deemed to add value, or if they come from many hand mapping efforts, they stay. The rest are mechanically trimmed.
