Fair Use of search engines, Facebook, local newspaper, etc

As an aside, another question you may want to ask is if it is worth adding additional information if you live in an area that is seldom updated.

There was even an Indian restaurant which closed about ten years ago, still tagged as open.

I take a middle ground approach and add a link to the website or Facebook page (after verifying it is the correct one) to allow consumers to easily find them. That way hours and other information the business wants to put out there is easily accessible and the burden to keep it up to date doesn’t fall on OSM mappers. There is also no concern as to copyright as you are not copying any information.

While having that additional information is nice, having outdated information is harmful for usability and adoption of OSM based consumers.

Facebook has apparently fed much of their business listing data into Overture, which could be a less encumbered route to obtain this information. The same caveats about accuracy still apply, however.

I think Overture will pave the way to bridge this information gap in the future, but will take time and proper validation linking the datasets (hopefully a tag like Wikidata, but for Overture).
