Parser rules describe and define the expected composition of a data string to be analyzed using the ANTLR symbols

Using parser rules this way allows you to normalize and standardize the analyzed data according to your expectation. Parser rules can also be called standardization rules.

For example, a parser rule reading <INT><WORD+><StreetType> defines a standard address data format like 12 main street.

You can create a set of parser rules either form the DQ Repository tree view in the Profiling perspective of Talend Studio or from the Basic settings view of the tStandardizeRow component. However, when you need to test, store and manage the sets of parser rules for purposes such as sharing, reusing, or adapting any given set of rules, you must use the DQ Repository tree view.

For further information about how to create and use parser rules to analyze, normalize and standardize data using tStandardizeRow, see Talend Components Reference Guide.
