Currently, Alma’s implementation of the SIP2 protocol uses only a limited subset of the available data fields. This restricts the potential of SIP2 integrations with self-check machines and other automated systems.

For example, patron age or birth date information is not transmitted via SIP2 messages. As a result, self-check units cannot automatically block the checkout of restricted materials (e.g., DVDs or other items not permitted for users under 16).

We propose that Alma extend its SIP2 message support to include additional patron details such as birth date and/or age

This enhancement would enable safer and more autonomous self-service environments, particularly in low-staffed libraries, while ensuring compliance with age-based borrowing restrictions and institutional policies.
