I've been using semi-colon-separated values like 
source=survey;image;usgs_imagery;LACA to indicate that I:

- Drove the street (survey)
- Took a picture of the street sign (image)
- Traced it from the USGS satellite imagery (usgs_imagery)
- Confirmed the name with the LA County Assessor's maps (LACA)

The source generally implies what type of information was used from it, 
though there is some overlap (like using tract maps to provide exact 
measurements for new streets or those with unclear imagery).

I have no opposition, though, to the more precise:

source:location=survey;usgs_imagery + source:name=survey;image;LACA
