Hi,

https://www.openstreetmap.org/edit?node=11033999562

If it is this:  https://www.bing.com/maps?cp=52.653116%7E-7.255996&lvl=17.0&v=2&sV=1&pi=-22.6&style=x&dir=20.6

You can tag it like this: https://www.openstreetmap.org/node/9257813117

But use
name=The Maltings 
ref=0II4S2Z
location=indoor

The ref is normally in the form of 999999z, so I suspect the letters in the ref are meant to be numbers.
