Metadata and standards

Metadata defines how data is structured, interpreted, and validated across systems. It is the foundation that enables organizations to exchange and compare information consistently, regardless of jurisdiction or language. For CDQ, metadata is essential to make data sharing possible at scale and across borders.

Because regulatory and business requirements change over time, metadata must evolve dynamically. CDQ maintains a continuously updated metadata repository that captures national and sector-specific data rules, such as address formats, identifier structures, and legal form codes. This ensures that shared and validated data remains semantically correct and compliant across all contexts. By sharing standardized metadata, CDQ enables customers to align their data models and validation rules, making collaboration efficient and legally sound.

In many countries, official company information is available as Open Data, but the lack of a standardized data model or provision method complicates the process of integrating this data. The Data Sharing Community actively collaborates to identify global data requirements and reference data sources, whether Open Data or commercial.

Ensuring data quality is crucial for businesses seeking to maintain compliance with ever-evolving legal, regulatory, and industry standards. In today’s global environment, adhering to dynamic data requirements is a continuous challenge, as these standards frequently change based on national regulations. As regulations vary by country, organizations must track and update their compliance criteria to ensure alignment across all jurisdictions they operate within.

Many countries offer official company information as Open Data; however, the absence of a standardized data model or provision method complicates the process of integrating this data into business operations. The Metadata and Standards initiative within the Data Sharing Community aims to address these challenges by identifying and aggregating global data requirements and reference data sources -- whether Open Data or commercially sourced. Through this collaborative effort, businesses can ensure they have access to accurate, reliable, and standardized data that is critical for compliance and risk mitigation.

By leveraging this structured and standardized metadata, businesses can ensure compliance with complex and diverse regulatory frameworks, improve data quality, and streamline integration across global systems. The Metadata and Standards approach ensures that companies have access to reliable, high-quality reference data, enabling them to stay compliant, reduce risk, and make informed decisions.
