ISO/TR 7340:2023

Overview

ISO/TR 7340:2023 - "Reference data distribution in financial services" - is a Technical Report that provides guidance on the architecture, technologies and operational controls for distributing reference data across financial systems. It covers distribution modes (centralized and distributed), logical and physical implementation models, data management (storage and security), service quality control and interaction patterns for publishers and subscribers. The report targets efficient, reliable and secure reference data distribution and helps enable real‑time synchronization, accuracy and consistency of financial reference data.

Key topics and technical requirements

• Design principles: compatibility, data accuracy, high availability, extensibility, security and maintainability as core requirements for reference data distribution.
• Distribution modes: centralized (traditional) and distributed (emerging, including distributed ledger technology) approaches for publishing and consuming reference data.
• Related technologies: commentary on mainstream protocols and platforms such as FinTech integrations, WebSocket, AJAX, RMI, blockchain and P2P; considerations for choosing technologies based on use case.
• Logical model: publisher/subscriber structure, domains and topics, distribution workflows, task scheduling and modular publisher/subscription components.
• Physical model: broker‑based architectures and non‑broker options (e.g., multicast and P2P), plus interaction views from publisher, subscriber and smart contract perspectives.
• Data payload and types: syntactic and structural guidance for payloads (general principles rather than prescriptive formats).
• Authority and privacy: access control and privacy protection for sensitive reference data.
• Security: layered security requirements covering data security, transport security and application security.
• QoS control: service quality controls including latency, consistency, deadlines and reliability to meet operational SLAs.
• Use cases: practical broker and non‑broker scenarios illustrating deployment choices and trade‑offs.

Practical applications and who should use it

ISO/TR 7340 is aimed at organizations and practitioners involved in the creation, distribution and consumption of reference data in financial services:

• Data distributors and market data providers designing distribution platforms.
• Banks, clearing houses and exchanges implementing synchronization and feed services.
• FinTech vendors and integrators building RDIs (reference data interfaces) and middleware.
• Systems architects and data engineers selecting architectures (broker vs. non‑broker) and QoS controls.
• Security and compliance teams assessing access control, privacy and transport/application security. Adopting the guidance helps reduce information asymmetry, improve operational resilience and enable new distributed solutions such as ledger‑based distribution.
