Do you have different tags from OSM for common things like name, so a 
naming conflict end up looking like this afterwards (hopefully not):


Are you dealing with separating directional prefix/suffix from the name (if 
that was an issue in OR)?

FWIW, when I correct existing (mostly TIGER-import) road names in OSM based 
on research into county assessor's map, tract/parcel maps, and surveys, I 
tag the relevant document number on the feature I corrected, in case 
someone wants to see why it was changed. e.g.:

        I aligned to this sat img I saw the street
        |                         |      I photo'd the street sign
        |                         |      |     I used San Bernardino County 
Assessor docs
        |                         |      |     |    I used San Bernardino 
County Surveyor docs
        |                         |      |     |    |

+ source_ref=AM909_DSCX1234;AM0220-19;TR12345-04
              |              |         |
              My photo #     SBCA map  SBCS Tract map

I'll also add a FIXME tag if the signage is known to be wrong, noting to 
whom the problem was reported and when. In such cases, I also usually add 
an alt_name tag with the bad sign value, and hopefully come back later and 
remove it after resurvey of the new sign.
