[talk-au] Tagging Asset ID's (bridges as a priority)

[Andrew Hughes]

Hi All,

Thanks for all the replies, very helpful. The bridge name seems very clean
cut.

The asset id, requires more research but first I will have a look into
nominatim to see how it could influence how it can play a part in locating
assets by their ID.

Thanks again, got the job done!
