Testing Your Mapping
To map the fields, configure these parameters:
Choose the Selector: This specifies XPath query to a specific metadata record element to be selected.
Enter the Field Name: This is the target field in Voyager that gets mapped to the specified metadata output.
Confirm the Type: This refers to the data type of the field name. For example, if field name is set to “name”, data type automatically gets set to “text.”
Choose an Action: Users can select from five different functions:
Set Field— Assigns value to the specified field
Append Field—Adds to/modifies pre-existing field
Set Geo—Sets a geographic bounding box based on coordinates specified in the metadata
Expand Geo—Expands geographic bounding box from previously set coordinates
Add Link—Helps point field to a URL
Converter - Converter settings are optional and if the user does not specify one, Voyager, by default, assigns an appropriate converter to the field.
Bbox -- Converts bounding box values contained in the XML document
Gml_Geometry -- Converts geometric (line, circle etc) coordinates from the XML document
Date -- If the Date field is represented as a string value in the XML document, this converts it into a standard date format
String256 -- Finds a String within the element with a maximum length of 256 characters
String512 -- Finds a String within the element with a maximum length of 512 characters
StringValue -- Finds a String (of any length) within the element

For example, here the Field Name is City, whose data type is String.
NoteNOTE: when selecting a field name you'll need to either select an existing field name or you can also enter a custom field name as long as it uses a prefix "meta_", "id_".
