Very important. In archeology, the exact location where an object is found must be recorded. Usually the horizonal location, and sometimes the vertical location. Also, as for best practices recommendations with Asman, the date should also be recorded. And this information should be exposed in a human readable format, again, for best practices. When possible, the tag should be assigned directly to the object in question, to avoid the tag getting lost in relation to the object. Otherwise, the best that can be done is to place the tag within the object’s proximity.

Whoops! I’ve misspelled archaeology, have I? This is the actual way that I wanted to spell it in my writings.
