Abstract

Abstract:

Dataspace is the transformation of cyberspace from ＆quot;computing centric＆quot; to ＆quot;data centric＆quot;, which contains great technological issues and innovative opportunities.Similar to the internet, which is the main infrastructure of cyberspace, dataspace also needs a new ＆quot;data-centric＆quot; infrastructure, whose core function is to realize the first-class entity of data.From the perspective of dataspace, the supports and shortcomings of mainstream technologies such as the internet, the World Wide Web, and the digital object architecture for the first-class entity of data were analyzed and summarized, and then the basic connotations and technical challenges of dataspace infrastructure were given.Finally, a first-class data substantialization method based on data pragmatics was proposed.Based on this method, a solution called the internet of data by integrating digital object architecture, distributed ledger, smart contract, and other technologies was proposed to support the construction and operation of internetscale dataspace infrastructure.

Key words: infrastructure of dataspace, internet of data, DOA, data pragmatic
