Abstract: As a future technological form of the internet,the metaverse is characterized by deeper open interconnectivity.By integrating information technologies such as virtual reality,digital twins,and blockchain,the metaverse can provide services and experiences that combine the virtual and the real in various application scenarios,including office work,performances,tourism,and gaming.A key aspect of achieving this technological goal is the interconnectivity and interoperability of social data resources.However,issues such as unclear data ownership,unclear benefit attribution and difficulties in controlling security risks hinder the flow and integration of data resources.From the perspective of data relationship theory,the economic value of data comes not only from the information content included in the data itself but also from the social relationships reflected between data,corresponding to individual rights and group rights at the rights level.Different types of rights imply different protection models and governance paths,requiring the realization of governance effects for data interconnectivity and interoperability from four levels:usable standards for data formats,rules for group data use,rules for joint benefits of public and private data,and special data security assessments.

Key words: metaverse, data, data interconnectivity and interoperability, digital economy, data relationship
