way/477331702/history has building:part = 3

What this tag means? Numeric value is unexpected here and it is unclear what it means

way/1427627745/history has shop = fruit

shop=fruit ? Maybe shop=greengrocer was intended? If they truly sell solely only fruit then maybe extra tag like greengrocer=fruit would be better? If they sell also vegetables then shop=greengrocer is definitely better.

shop=greengrocer is far more widely used and supported and does fit even if only variety of fruits is sold.

But maybe another shop tag would fit better? Maybe shop=farm? ( shop=farm )

Definitely not a separate building - is it even a building part?
