Service-oriented data trading indicates that the property-based trading model cannot provide stable returns for both parties in data trading. Market entities spontaneously hide data and combine it with digital technology in specific data application scenarios to provide data services to buyers. But, in doing so, the registration of data assets as property rights becomes untenable. The public nature of data elements and the private nature of property rights creates a contradiction because the sharing of data elements cannot be reconciled with the exclusivity of registered rights. Therefore, the initial logic of registration and rights confirmation should be abandoned. Instead, the institutional function of data asset registration should transformed into confirming data asset compliance and security. Data resources and data products can then be established as registration objects. Formal requirements should be established that are based on “material compilation principle”, “basic information, application scenarios, data sources, data structure, update frequency and technical rules”, and “compliance and security descriptive matters.” Registration types can be created based on compliance registration, security registration, and contract filing registration. Registration should be given corresponding legal effect, thus forming the core architecture of the data asset registration system. Finally, based on the logical transformation and core architecture of data asset registration, a “1+(M+N)+Xx” organizational system and model for data asset registration should be constructed as well as a “unified, multi-level, and multi-dimensional” normative support system.
