Note
The DataMapper only extracts elements for which at least one value is defined in the file. Attribute
values are not taken into account.
Attribute values (prefixed with an @ sign in the Data Viewer) are not extracted automatically.
Click Finish to close the dialog and open the data mapping configuration.
Data mapping workflow
A data mapping workflow is a series of extraction instructions, called steps. These steps
process and extract the data from the source and store them in records, of which the structure is
determined in the Data Model (see "The Data Model" on page202). Together with the data
source settings, the Data Model, and the sample data, this is what makes a data mapping
configuration (See "Data mapping configurations" on page151).
The data mapping workflow is shown on the Steps pane at the left (see "Steps pane" on
page266).
Creating a data mapping workflow
A data mapping workflow always starts with the Preprocessor step and ends with the
Postprocessor step. These steps allow the application to perform actions on the data file itself
before it is handed over to the data mapping workflow ("Preprocessor step" on page191) and
after the Data Mapping workflow has completed ("Postprocessor step" on page201).
When you create a new data mapping configuration, these steps are added automatically, but
they don't actually do anything until you configure these steps.
In between the Preprocessor and Postprocessor step, the workflow can contain as many steps
as needed to extract the required data.
Adding steps
Extracting data is the main way to build a data mapping workflow; see "Extracting data" on
page169.
Extract steps, Condition steps and Repeat steps can be added after selecting data in the Data
Viewer.
All steps can be added via the Steps pane:
