Sun Match Engine Match and Standardization Types

Indicators are used in the Match Field file to reference the type of matching and standardization to perform on each field. You must specify one of these indicators, called match types and standardization types, for the fields you define for standardization or matching. The match types correspond to the match types listed in the first column of the match configuration file (matchConfigFile.cfg). The standardization types are defined internally in the match engine. The Sun Match Engine uses these types to determine how to process each field.

Table 4 lists the default standardization types; Table 5 lists the default match types. You can modify the match type names but not the standardization type names. For more information about match and standardization types, see Master Index Match Types and Field Names (Repository) in Understanding Sun Master Index Processing (Repository). Note that the match types you can specify in the Match Field file (listed in Table 5) are not the same values you specify for the Match Type field drop-down list in the wizard when you create the master index application.

Table 4 Standardization Types

Address	Free-form street address fields.
