rules table

Primary key of table

text field denoting the rule. Details at PAGC Address Standardizer Rule records .

A rule consists of a set of non-negative integers representing input tokens, terminated by a -1, followed by an equal number of non-negative integers representing postal attributes, terminated by a -1, followed by an integer representing a rule type, followed by an integer representing the rank of the rule. The rules are ranked from 0 (lowest) to 17 (highest).

So for example the rule 2 0 2 22 3 -1 5 5 6 7 3 -1 2 6 maps to sequence of output tokens TYPE NUMBER TYPE DIRECT QUALIF to the output sequence STREET STREET SUFTYP SUFDIR QUALIF . The rule is an ARC_C rule of rank 6.
