Mainly interested in tourism- related POIs (for usage with apps) and shops. https://wiki.openstreetmap.org/wiki/Tourism_tag_overview

As there are many shops which offer very different items or services, (which cannot be subsumed in a certain shop type), IMHO a general namespace tagging scheme should be established to express shop details, i.e. which services or goods they offer. http://wiki.openstreetmap.org/wiki/Namespace

As an example, see shop=motorcycle, shop=ski or shop=boat. In most cases, this will be sales, rental, repair and parts. So if a car shop also sells motorcycles and/or bicycles, you could use the “service” tags bicycle:sales=yes motorcycle:sales=yes motorcycle:rental=yes car:rental=no This way there’s no need to create a separate shop.

There are currently two apps supporting motorcycle POIs : https://kurviger.de http://osmand.net Also check taginfo : https://taginfo.openstreetmap.org/projects/osmand#tags (search for “motorcycle” and order it by count).
