ISO 10161-1:2014 PDF

Overview

ISO 10161-1:2014 - "Information and documentation - Open Systems Interconnection - Interlibrary Loan Application Protocol Specification - Part 1: Protocol specification" defines the application‑layer protocol for ISO interlibrary loan (ILL) services. It provides the formal rules of behaviour for systems that participate in ILL transactions (requesters, responders, and intermediaries), specifying how systems must act on received service requests, received APDUs (Application Protocol Data Units), and local system events. The standard focuses on interconnection between systems and does not mandate internal interface implementations.

Key topics and technical requirements

• Protocol behaviour and state machine: Detailed protocol states, transaction identification and protocol variables, including expiry timer handling and history information.
• ILL APDUs and abstract syntax: ASN.1 specification of ILL APDUs (Clause 9), with encoding/transfer syntax guidance (Annex B) referencing EDIFACT rules (ISO 9735).
• Procedural rules: Events and actions for all parties, plus special procedural rules for intermediaries (Clauses 7–8).
• Conformance: Static and dynamic conformance requirements and Protocol Implementation Conformance Statement (PICS) requirements (Clause 10). Part 2 of ISO 10161 provides a PICS proforma.
• Normative annexes: State tables (Annex A), transfer syntax (Annex B), object identifier assignments and registration requirements (Annex C, D), and informative guidance on supporting services and document delivery integration (Annexes F–G).
• Supporting standards referenced: ASN.1 and BER/DER encoding rules (ISO/IEC 8824 / 8825), ISO 10160 (ILL service definition), ISO 9735, and other data format and identifier standards (ISBN, ISSN, ISO 8601, etc.).

Practical applications and who uses this standard

ISO 10161-1:2014 is intended for:

• Libraries implementing automated interlibrary loan workflows.
• Union catalogue centres and information utilities that broker or route ILL requests.
• Vendors and developers building ILL servers, clients, or intermediary gateways.
• Consortia and resource-sharing networks that require standardized, interoperable ILL messaging across heterogeneous systems.

Practical uses:

• Ensures interoperable ILL exchanges across systems from different vendors and platforms.
• Enables multi‑party ILL topologies (two‑party and multi‑party interactions) with defined behaviour for request forwarding, response, and document delivery invocation.
• Supports both automated and operator‑mediated invocation of external document delivery services.

ISO 10161-1:2014 is essential reading when implementing interoperable interlibrary loan systems or integrating ILL functions into library services, offering a formal, standards‑based foundation for reliable ILL communications.
