let's standardize sites

No objections from here, as long as label can still hold a "string".
I have site lists in which I use this field to house a wierd string
which is the name of the site. It might be better to call all this:

east|north|#serial_number attribute

then it is clear what each field is for?

Regards

Simon Cox
