Most common tags?

Hi,

I’d like to import OSM data into Google Earth Engine, which doesn’t support sparse tags. Ideally, I’d like to to choose a few hundred most commonly used tag keys and only keep those tags on imported data.

I can simply count the keys and choose the top X most frequently used ones, but I think something similar happens during imports to PostGIS. If there is a small list of standard tags somewhere, can someone point me at it?

Thanks,
Simon

No idea what you try to do but TagInfo is probably of help:
https://taginfo.openstreetmap.org/
and esp. https://taginfo.openstreetmap.org/tags

A list at https://wiki.openstreetmap.org/wiki/Map_features on significance independent of instances, not sure if “small”.

Thank you!
