The new Nlets Standardized XML Mandate requires that all messages exchanged between the Nlets system and the CTA message broker be fully tagged documents (ideally in the NIEM 4.0 format). This applies to all types of messages, including message types that are typically untagged and unstructured (e.g., database responses).
‘Structured’ messages (like queries) have always been tagged; converting these messages to NIEM is easily solved by the message broker alone. Converting unstructured response messages to NIEM, however, is a challenge. In this paper, we will address common questions to bring further clarity to the mandate and compliance with it.
