What is BS EN ISO 10209-2021?

BS EN ISO 10209-2021, also known as the British Standard for Information and Documentation - Working Fields of International Standard Identifiers (ISIs), is a technical document that provides guidelines for the use of ISIs in various industries.

The Purpose of BS EN ISO 10209-2021

The main purpose of BS EN ISO 10209-2021 is to establish a standardized framework for the implementation of ISIs, ensuring consistent identification and organization of information across different sectors. ISIs are unique codes used to identify and categorize various types of information, such as documents, books, or products.

This standard aims to improve information management by facilitating efficient retrieval, exchange, and integration of data through the use of ISIs. It helps organizations streamline their processes, reduce errors, and improve interoperability between different information systems.

Key Features of BS EN ISO 10209-2021

BS EN ISO 10209-2021 defines the structure and syntax of ISIs, outlining rules for creating and assigning identifiers. It specifies the format, length, and character set of the identifiers to ensure uniqueness and compatibility across diverse applications.

The standard also provides guidelines for the registration and maintenance of ISIs, establishing procedures for resolving conflicts and managing changes. It emphasizes the importance of accurate metadata, such as descriptions, relationships, and classification schemes associated with ISIs, enabling better understanding and interpretation of the identified information.

Furthermore, BS EN ISO 10209-2021 encourages the integration of ISIs into existing information management systems, promoting interoperability and harmonization. It highlights the benefits of using ISIs in enhancing search capabilities, facilitating data sharing, and supporting efficient information exchange both within and between organizations.


BS EN ISO 10209-2021 plays a crucial role in standardizing the use of ISIs across industries, enabling efficient information management and exchange. By implementing this standard, organizations can achieve improved interoperability, streamlined processes, and enhanced search capabilities. It provides a foundation for consistent identification and organization of information, ultimately leading to better decision-making, increased productivity, and improved collaboration.
