Definition: The Catalogue of Harmonised Tax Data Ontologies is a comprehensive resource that provides a structured representation of tax-related data and concepts. It is designed to facilitate the exchange of tax data and information between different systems and platforms, thereby improving interoperability and data consistency. Source: OECD Source reference: https://www.oecd.org/tax/automatic-exchange/common-reporting-standard/ Additional information: The Catalogue of Harmonised Tax Data Ontologies is a crucial tool in the field of tax data management and analysis. It provides a standardized framework for representing tax-related data, which can be used to facilitate data exchange, improve data consistency, and enhance interoperability between different systems and platforms. The catalogue includes a wide range of ontologies, each of which represents a specific aspect of tax data. These ontologies can be used to model tax data in a way that is both machine-readable and human-understandable, thereby enabling more effective data analysis and decision-making. The catalogue is continually updated and expanded to reflect changes in tax laws and practices, ensuring that it remains a relevant and valuable resource for tax professionals and researchers. Example: For instance, a tax authority could use the Catalogue of Harmonised Tax Data Ontologies to standardize the representation of tax data in its systems, thereby improving data consistency and facilitating data exchange with other tax authorities. Similarly, a tax software developer could use the catalogue to ensure that its software is able to interpret and process tax data in a standardized way, thereby enhancing interoperability with other systems and platforms.
