Map File Columns to Attributes

You must map columns with the attributes of the Reltio Data Model before the data load.

This task explains how to define a mapping between file columns and entity attributes before loading entities.

On the Upload page, after you have selected a file, you are redirected to Mapping page. The content of the file that you have uploaded in the Upload page will be displayed.

  1. On the Mapping page, click on Map Attributes.
    Note: On the mapping page, you can start mapping attributes even if you do not select an existing mapping. After you saved the mapping the name will be New mapping, which you can change and add any other relevant name.

    You can select an existing mapping or search for an existing mapping from the list.

    You can sort existing mappings in the ascending or descending order based on:
    • The user who created the mapping
    • The date on which the mapping was created

    In the Select mapping dialog box the mappings are sorted based on the ascending order of Created by field. You can also filter mappings to refine your search.

    If you select an existing mapping, the CSV columns are mapped to entity attributes based on how the mapping is defined.

  3. In the Select mapping window, click New Mapping.
    You can create a new mapping.
    Note: By default, the name of the new map is New Mapping. Once the new mapping name is created this name will be stored inside the cache.

    In the Select Mapping dialog box, the Mapping Name text box is displayed with the name of a new mapping.

    Note: The Select mapping button label does get changed after the new mapping is created. It will be changed only when you select the existing mapping.

The Full Name column is mapped to the First Name and Full Name attribute in the image above. The following image shows that the Full Name attribute is unmapped when you click the cross icon.

    You can add a default value to any attribute (simple or nested) without mapping the attribute to any column of the input file.
