ISO 10160:2015

Overview

ISO 10160:2015 (identical to ISO 10160:2015) is an Application Layer standard in the Open Systems Interconnection (OSI) framework (ISO 7498). It defines the application service semantics for Interlibrary Loan (ILL) transactions - i.e., the services that allow library systems and information utilities to request, provide, forward and manage loaned bibliographic material and related messages. The standard specifies service behavior and sequencing but does not prescribe specific product implementations or constrain internal system architectures.

Key topics and technical requirements

• Service model and roles: clear definitions for service-user and service-provider roles and for system roles as requester, responder, and intermediary.
• ILL-transaction types and topologies: support for simple two-party, chained, partitioned and multi-party interactions; forwarding, referrals and retries are described.
• Transaction state model: requester-, responder- and intermediary-specific states, terminal states and transaction phases.
• Service definitions: a comprehensive set of ILL services and their semantics, including (but not limited to):
  • ILL-REQUEST, FORWARD, FORWARD-NOTIFICATION
  • SHIPPED, RECEIVED, RETURNED, CHECKED-IN
  • ILL-ANSWER, CONDITIONAL-REPLY, CANCEL, CANCEL-REPLY
  • RECALL, OVERDUE, RENEW, RENEW-ANSWER
  • LOST, DAMAGED, MESSAGE, STATUS-QUERY, STATUS-OR-ERROR-REPORT, EXPIRY
• Sequencing and robustness: rules and guidance for sequences of primitives, resilience to lost or out-of-sequence messages, and state-transition rules.
• Specification method: notation and conventions for expressing service behaviors; informative annexes include time-sequence diagrams and document delivery guidance.
• Implementation independence: the standard focuses on service semantics rather than protocol encoding; conformance is required at the ILL protocol specification level rather than to this service definition itself.

Practical applications - who uses this standard

• Libraries and consortia integrating ILL features into library management systems (LMS) or discovery layers.
• Union catalogue centres and information utilities that mediate or route requests across multiple resource providers.
• Vendors and integrators developing interoperable ILL solutions or adapters between messaging infrastructures.
• Use cases include automating request/fulfillment workflows, enabling multi-party loan routing, handling recalls/renewals, and ensuring consistent status/error reporting across heterogeneous systems.

Related standards

• ISO 7498 - OSI reference model (framework context)
• ISO/IEC 10021-4 (MOTIS) - example of a store-and-forward messaging service referenced as a supporting telecommunications service
• ISO 8822 and ISO 8649 - referenced for direct connection-mode service support

SIST ISO 10160 is essential for organizations that need a standards-based, implementation-independent definition of ILL service behavior to achieve reliable interoperability and predictable transaction handling across diverse library systems.
