Hi, Had a query regarding the OSM file's tags and values. I came across files where there are inconsistencies in tag names and certain node ids/uids do not have tag names and thereby don't allow us to identify what feature it is without opening them in any GIS software. For example, some node ids and uids have tag names as "source bing". Is there a way to identify what they represent without opening them in GIS software? Also, How does OSM recognize these features without proper tag names and values?

Thank you!

Many nodes are just there to build a way object from them. This means while a node might represent a wind turbine, a node might also just represent one of 20 points that make up the building footprint of a wind turbine. In these cases, the node will be a member of a way object and that way object will have the tags you are interested in.
