Here is an example of how it works: https://gist.github.com/omangin/fa5de41341c613a03c55. Various information can be added into the properties fields. They are displayed on click.
I guess a list of recommended information could be useful. To start:
- owner
- full address
- contact
- version / model
- assembly date
…
Also it seems possible to display the same information in google map:
