Data parsing based on format file

During Firco Trust screening, Evelyn can process the following data feeds to retrieve data fields for alert disposition:

• Security
• SSI
• Brokers
• Employees
• Investors
• KYC

Preparing data for screening

Before screening, send the data to be parsed in the RAW format within the MessageData tag of a Firco message. A Firco message contains two XML tags from which data can be extracted:

• <fir:MessageData>
• <fir:CustomerInfo>

Additionally, you must prepare a format file:

1. Configure a format file for either a Firco Unit or a Firco Business Unit, using the following naming conventions:

   • For a Firco Unit: <unit>_format.csv
   • For a Firco Business Unit: <bunit>_format.csv

2. Make sure to meet the following requirements for the format file:

   • The file must have a CSV extension.
   • The index and nss_column headers are required. All other headers are skipped if present. If the required headers are missing, CustomerInfo is used for mapping, with information logged in Control Tower.

   A sample format file looks as follows:

   

3. In MinIO S3, place the format file at the following path: doc-upload/name_sanctions_screening/firco_format_files/.

For example, you have the following configuration:

• Unit: CIF1
• Business Unit: SECURITY Then, Evelyn checks the predefined location for the following files in order and uses the first available file for processing:
• CIF1_format.csv
• SECURITY_format.csv

info

Filenames are not case-sensitive.

Mapping process

When running, Evelyn searches for a format file. If no matching format file is present or if the format file is empty or invalid, MessageData is not processed. If a format file is found, Evelyn starts the mapping process:

1. Extracts data from <fir:MessageData> in a Firco response.

2. Breaks down the pipe-separated data ( | ).

3. Using the format file, maps corresponding values from MessageData into ScreenedData.

4. After successful mapping, applies the same process to CustomerInfo to enrich ScreenedData further.

   As a result, ScreenedData contains information from both sources.

Collections such as Addresses, Dates, Aliases, and AdditionalInfo are included. If ScreenedData.name is missing due to issues with MessageData, the name from CustomerInfo is used instead. In other cases, names from CustomerInfo are added to Aliases to avoid overwriting. Evelyn ensures that no duplicate entries are created.

If a format file is not found, the fallback mapper uses CustomerInfo to map ScreenedData, with the corresponding message logged in Control Tower logs.
