Crosswalks provide a way to uniquely analyze the source-provided attributes in Reltio.

1. On the main Map page, select the required column.It will open the Attributes Panel on your right.
   For more information, see Map File Columns to Attributes.

   OR

   Click Map Attributes.

   

2. On the Map dialog box, click Crosswalks.

   

3. Click ADD.
   The new Crosswalk is displayed. For example Crosswalk1.

   

4. Expand the Crosswalk.

   The Type and Value fields are displayed.

   

5. Map the Type field.
   For example, HMS.

   Also, you can set a default value to the Type field. This will help you if the value for the Type field is missing in the column.

   

   When you hover over the Type field, a Gear icon appears.

6. Click the Gear icon.
   Using the icon, you can set a default value for the Type field. For example, HMS, Linkedin, Facebook. The Advanced Settings is displayed beside the Type option.

   

7. Map the Value field.
   The value helps you to validate a crosswalk.

   Note: You can map fields related to the crosswalk. For a valid crosswalk, you must map Type and Value fields.

   

   Note: While mapping the Type field, you must make sure that the values in the column are valid sources. If a mapped source is invalid, the particular record will fail to load.
8. Click Advanced Settings.
   The options available are as follows:

   • Source table
   • External info
   • Create date
   • Update date
   • Delete date

     See the Table 1: Advanced Settings: Options which explains the available options displayed for Advanced Settings.

     Table 1. Advanced Settings: Options

     Options	Description
     Source table	This is an optional property. This is the reference to the table in the external data source from where the data came from.
     External info	This is an optional property. This object describes information from external systems.
     Create date	This is an optional property which indicates the date when the crosswalk was created. For example, 2021-07-27T06:12:55.000Z, 2021-07-27T06:12:55Z, or timestamp.
     Update date	This is an optional property which indicates the date when the crosswalk was updated the last time in the original source (not in Reltio). For example, 2021-07-27T06:12:55.000Z, 2021-07-27T06:12:55Z, or timestamp.
     Delete date	This is an optional property which indicates the date when the crosswalk was removed. For example, 2021-07-27T06:12:55.000Z, 2021-07-27T06:12:55Z, or timestamp.

   Note: The Advanced Setting option is available for Create date and Update date settings only.
9. In the Advanced Settings option, map the Date options to valid Date columns.

   The loaded data will have crosswalks with the mapped dates (Create date, Update date, or Delete date).

10. Hover over the Gear icon beside Create date option.
11. Select the appropriate radio button.
    If the Create Date is missing, set the value from the Date Picker. From the date picker, you can select a date and time.

    The specified date and time are the default values for Create date.

    The record value will be set as Null.

    For example, 2021-07-27T06:12:55Z

    By default, the Create date and Update date are set.

15. Select either the Data Provider or Contributor Provider checkbox.
    Select Data Provider when you are loading data from the main data source. Alternatively, select Contributor Provider when you load additional data from a different source.

    Note: By default, the Data Provider is selected.

    

    While adding a crosswalk, Data providers supply attribute values. All the attributes provided in the request body will be associated with the crosswalk.If an entity with a matching crosswalk value already exists, then the existing attributes associated with the crosswalk will be overwritten, fully or partially, by the new attribute values.

    

    When you select Contributor Provider, no attributes will be associated with the crosswalk. If an entity with such a matching crosswalk value already exists, the existing attributes associated with the crosswalk will not be affected.

    

    Note: If there is no existing crosswalk, a new empty crosswalk (without attributes) will be created.
16. Click the Delete icon to delete a crosswalk.

    

17. Click the Downward arrow as follows:
