Big Data Update: Series on Data Reference Architecture Released


Adapted from

Big data analytics can help businesses identify new opportunities by capturing information on products and services, buyers and suppliers, and consumer trends and preferences. It can also support and improve operational efficiency and provide companies with a competitive advantage based on these insights. A new five-part series of standards and technical reports establishes a big data reference architecture (BDRA) and framework, which organizations can use in order to achieve interoperability between BDRA systems.

The ISO/IEC 20547 series was developed by the International Organization for Standardization / International Electrotechnical Commission (ISO/IEC) Joint Technical Committee (JTC) 1, Information Technology, whose secretariat is held by the American National Standards Institute (ANSI). The series includes:

  • ISO/IEC TR 20547-1Information technology – Big data reference architecture – Part 1: Framework and application process
  • ISO/IEC TR 20547-2Information technology – Big data reference architecture – Part 2: Use cases and derived requirements
  • ISO/IEC 20547-3Information technology – Big data reference architecture – Part 3: Reference architecture
  • ISO/IEC 20547-4Information technology – Big data reference architecture – Part 4: Security and privacy
  • ISO/IEC TR 20547-5Information technology – Big data reference architecture – Part 5: Standards roadmap

ISO/IEC 20547, parts 1, 2, 3 and 5, were developed by JTC 1 subcommittee (SC) 42, Artificial Intelligence, while part 4 was developed by JTC 1 SC 27, Information security, cybersecurity, and privacy protection, whose secretariats are held, respectively, by ANSI, and DIN: German Institute for Standardization, ISO’s member for Germany.

“At the heart of the fourth industrial revolution is the ability to derive insights in an increasingly data-centric world. Big data computational systems enable this digital transformation across a wide variety of industry verticals," said Wael William Diab, chair of ISO/IEC JTC 1 SC 42, Artificial Intelligence. "These standards are in response to an increasing demand for greater clarity and consistency of concepts and processes in handling big data.”

“The BDRA addresses requirements, architecture, security and privacy, use cases and considerations that architects, application providers and decision makers will want to consider in deploying a big data system," said Wo Chang, convenor of ISO/IEC JTC 1 SC 42, Working Group WG 2, Data. "This will serve to increase trust and understanding amongst stakeholders and across the whole industry, ensuring big data technologies are interoperable and used safely and effectively.”


Since 1987, JTC 1 has addressed the rapidly changing standardization requirements of the global information and communications technology (ICT) industry. Highlighting a long history of U.S. leadership and engagement, ANSI holds the secretariat to JTC 1 and Phil Wennblom of Intel serves as chair. JTC 1 and its 22 subcommittees have had direct responsibility for the development of more than 3,200 published international standards, with hundreds more currently in development.
