ISO-IEC 11179-2:2021 is an international standard for data and metadata registries. It provides guidelines for the development and maintenance of registries, which are essential for managing and understanding data. This standard defines the principles and concepts that govern the structure and administration of registries.
The Purpose of ISO-IEC 11179-2:2021
The purpose of ISO-IEC 11179-2:2021 is to establish a common language and framework for describing data, promoting interoperability and data exchange between different systems. It offers a structured approach to organizing and cataloging data elements and their associated metadata, enabling better understanding and reusability of data across various applications and organizations.
Main Components of ISO-IEC 11179-2:2021
ISO-IEC 11179-2:2021 consists of several components. One key component is the data element concept, which represents the fundamental building block in the registry. Data elements are defined using a set of attributes, including names, definitions, and classifications. These attributes help provide comprehensive information about each data element, facilitating its effective use and management.
Another important component of ISO-IEC 11179-2:2021 is the value domain concept. Value domains define the acceptable values or ranges for specific data elements. They help ensure data quality and consistency by enforcing data validation rules. Value domains can be simple (e.g., a list of predefined values) or complex (e.g., mathematical formulas), depending on the nature of the data element being described.
Benefits and Implementation Challenges
Implementing ISO-IEC 11179-2:2021 offers several benefits to organizations. It promotes data interoperability, allowing seamless integration of data across different systems and applications. It also improves data quality and consistency by providing clear guidelines for data description and classification. Furthermore, it enhances data discoverability, making it easier for users to find and understand relevant data elements within the registry.
However, implementing ISO-IEC 11179-2:2021 can present certain challenges. One challenge is the initial effort required to define and populate the registry with all relevant data elements and their associated metadata. Organizations must invest time and resources in developing a comprehensive data dictionary that aligns with the standard's requirements. Additionally, ensuring ongoing maintenance and governance of the registry can be complex, requiring dedicated staff and resources.
