In the psbprint database, there are two related tables: “Users” and “Identifiers”.

  • Users is reasonably obvious, it contains most of the properties of a user (i.e. Location, email, Budget Centre, etc.)
  • Identifiers are, for want of a better description, something that can identify a user.  The two most common types of identifiers are NetworkIDs and CardIDs.  This means:
    • A user may have multiple identifiers.  E.g. It’s common for a user to have both a NetworkID and a CardID.  Also, It’s not unknown for a user to have multiple cards.  Multiple network IDs is also possible.
    • Network IDs can exist without Card IDs.  Card IDs can’t exist without network IDs.  Well, they can, but without a Network ID, a Card ID is useless. Greatly simplifying, this is because when a Card ID is used for Secure release, Blueprint needs to match the Card ID to a network ID, so Blueprint can find all jobs that are owned by that network ID.
    • Thus Network IDs are “higher value” than Card IDs to Blueprint.


The root identifier is the highest value identifier that Blueprint has for a User.  Usually, it is the first Network ID associated with a User.
