The Address Output Patterns File (addressOutPatterns*.dat)

The address output patterns file uses the field patterns output by the addressPatterns*.dat file to determine how to parse all standardized address fields. As with the addressPatterns*.dat file, tokens are used to indicate the type of address component in the input and output data. This file contains two rows for each pattern. The first row defines the input pattern received from addressPatterns*.dat and provides an example. The second row defines the output pattern (as shown below).

EI|BN BT|*          // HILLVIEW|FULBOURN HOSPITAL
BN|BI BY

The syntax of this file is:

input-pattern             example
output-pattern

You can modify or add entries in this table as needed. Table 19 describes the columns in the addressOutPatterns*.dat file.

Table 19 Address Output Patterns File


Column	Description
input-pattern	Tokens that represent a possible input pattern from `addressPatterns*.dat`. Each token represents one component and the pattern for each address field in the address is separated by a pipe (\|). For more information about address tokens, see Address Type Tokens. Note that this file only uses output tokens.
example	An example of a street address that fits the specified pattern. This file element is optional.
output-pattern	Tokens that represent the output pattern for the specified input pattern. Each token represents one component of the output of the Sun Match Engine. For more information about address tokens, see Address Type Tokens.

Following is an excerpt from the addressPatternsUS.dat file. In the first example, addressPatternsUS.dat outputs three address fields containing these components: building name and type; street name and type; and street name and type. addressOutPatternsUS.dat changes the tokens for the second street name and type to indicate they are not the primary street name and type. Therefore, “New Bridge” is populated into the parsed street name field in the database.
