When you’re mapping and you don’t have a definitive source for the start_date or end_date, but you can reasonably assume from a map where related items are or are not present, how should you cite the source?
When there is no definitive source outside of the mapper’s observation, should the start/end_date:source=*
value be:
- nothing at all
- A simple
"inference"
- e.g.,start_date:source="inference"
- A simple word, but not “inference” - please reply with an alternative suggestion below
- A text explanation - e.g.,
end_date:source="Item not on 1860 Baist map, but is on 1875 Sanborn map.
- A text explanation AND an edtf date - e.g., the text explanation tag above and
end_date:edtf=1860/1875
