It is possible that some supermarkets would make their list of products available electronically and thus provide an incentive for a clever hacker to simply convert that to OSM. Once we say we accept a list of products for a supermarket, few would make the distinction of "surveyed list = ok, imported list = not ok"... Such an automatic import would practically be the only way to keep a list of products current. > But I see no significant negative effects extending to other people > (shop element would be hard to edit for some time until somebody would > remove outdated data would be the largest problem what is not really > significant). A typical grocery store would carry about 30.000 different products. Even assuming it would be possible to encode each in a 15-character string, the "sells" tag would half a megabyte long - for each store. And update once a week. If this were done for many stores, the impact on the size of the planet file, the daily diffs, or even the small download you make to edit an area, would be noticeable. Thankfully, this is hypothetical because we won't do it. OSM is a geo database and not a sales directory.
