To effectively address the challenges in data factor circulation, this study focuses on data asset registration and explores its registration content system and the standardization thereof. By adopting the literature research method, drawing on registration practices in the field of information assets and natural resources, and integrating signal theory, information resource management theory, asset valuation theory, and data governance theory, it constructs a data asset registration content system consisting of information on the holding entities, content information, location information, value information, and compliance information.. Based on the registration content and relevant requirements, a unified metadata structure and data dictionary are designed to standardize the expression of registration content. From a practical implementation perspective, a data asset registration system framework composed of the user interface layer, application service layer, data persistence layer, and infrastructure layer is proposed, along with corresponding operational and management requirements.
