Match by Date (Blocking)

Finds matches between the DATE-columns in the inputs.

• A [OBJ,DATE]: a list of candidates, in which the DATE-column will be used for comparison and the OBJ-column will be the result
• B [OBJ,DATE]: a list of candidates, in which the DATE-column will be used for comparison and the OBJ-column will be the result
• Candidates [OBJ,OBJ]: candidate pairs, only As and Bs that are in Candidates will be matched

• RESULT [OBJ,OBJ]: the matched objects from A and B
• NOTA [OBJ]: the objects from A that did not match with an item from B
• NOTB [OBJ]: the objects from B that did not match with an item from A

• Comparison: Comparison function to use (=,!=,<,>,<=,>=,day-distance)
• Max day-distance: when Comparison is set to day-distance, the match is valid only if the difference in days between the two dates is not greater than this value
• Exclude self-matches: whether to emit the match if the objects in A and B are the same. Mostly useful when A and B come from the same source
