Model data contains the data for the model that the ModelTable argument specifies and the checksum of the stored data, for data integrity.

How data is stored depends on whether the data is in a database table or an installed file:

  • Database Table:
    • Time and timestamp SQLdata types are converted to acceptable scoring format.
    • Special characters are transformed as follows:
      Character Transformation
      Backslash (\) \\
      Comma (,) \,
      Ampersand (&) "&"
      Less than (<) "&lt;"
      Greater than (>) "&gt;"

      Binary data is stored using Base64 encoding.

  • Installed File:

    Data is captured in binary format (bytes) and stored using Base64 encoding in the AML file. Because of binary encoded format, special character handling is not needed.

Scorer expects only AML files generated by the AMLGenerator function. Third-party generation or manipulation of an AML file can cause scorer failure or incorrect scoring results.
