The Verifier transformation adds a verifier asset that you created in Data Quality to a mapping.
A verifier asset defines a template for input and output address data that you can connect to the input and output fields on the Verifier transformation. Connect the fields in your source data or in upstream transformations to the corresponding input ports on the Verifier transformation. Connect the output ports on the Verifier transformation to downstream transformations in the mapping or to the mapping target.
The Verifier transformation performs the following operations on the input address data:
•The transformation compares the address records in the source data to address reference data.
•It fixes errors and completes partial address records. To fix an address, the transformation must find a positive match with an address in the reference data. The transformation copies the required data elements from the address reference data to the address records.
•It writes output addresses in the format that the verifier asset specifies. You define a verifier asset in Data Quality to create address records that suit your business needs and that conform to the structure that the mail carrier requires.
•It can report on the deliverable status of each address and the nature of any error or ambiguity that the address contains.
•It can provide suggestions for any ambiguous or incomplete address.
For more information about the types of address information that the Verifier transformation can read and write, including address status information, consult the verifier asset documentation in the Data Quality online help.
A Verifier transformation is similar to a Mapplet transformation, as it allows you to add address verification logic that you created elsewhere to a mapping. Like mapplets, verifiers are reusable assets. A Verifier transformation shows incoming and outgoing fields. It does not display the address data that the verifier contains or allow to you edit the verifier. To edit the verifier, open it in Data Quality.
