An action plan for the development of trusted data matrixes (TDM) was recently issued by the National Data Administration (NDA).

China is expected to establish more than 100 TDMs by 2028, making breakthroughs in TDM operation, technology, ecology, standards and security systems, and significantly improving the level of data openness, circulation and use in various fields, according to the plan.

As a new data circulation and utilization infrastructure, TDM aims to achieve the sharing and common use of data and resources, which is also an important carrier needed to construct the national integrated data market.

The plan consists of three key tasks. The first is to implement TDM capacity building, by building trusted management capabilities, improving resource interaction capabilities, and strengthening value co-creation capabilities.

The second is to cultivate and promote TDM, including the construction and promotion of five types of TDM for enterprises, industries, cities, individuals and cross-border.

The third is to strengthen foundation-setting actions of TDM, focusing on formulating key standards, tackling core technologies, improving basic services, and expanding international cooperation.

The country will support leading enterprises in building enterprise TDM, cooperate with upstream and downstream enterprises to share high-quality data resources, and improve process efficiency.

It will also tackle key technologies for TDM, by promoting the integrated application of data interoperability technologies, and exploring the integration and innovation of large models and TDM.

Moreover, the plan proposed to actively expand international cooperation and participate in the formulation of relevant international standards.
