1.3.9.6 Map

The Map sub-processor of Parse is used to map the selected input attributes to the internal attributes used by the Parse processor.

Using internal attributes allows a Parse processor to be developed and configured independently of the actual names of the input attributes. This is useful because the same Parse processor can be re-used with multiple different data sources, which may provide differently named input attributes, simply by mapping the new input attributes to the existing internal attributes. There is no need to reconfigure any other options (such as which classification and reclassification rules to apply to which attributes).

Each internal attribute has a name (such as Title, Forename, Surname and so on) and a tag (usually a1, a2, a3 and so on). Tags can be used in the resolution phase of parsing, to allow the Parse processor to distinguish between token patterns which originate from different input patterns. See Using Attribute Tags for more details.

The attributes required by the parser are displayed on the left. Map your selected input attributes to these attributes in the right-hand column.
