3 Terms and definitions
The following terms and definitions are applicable to this document.
3.1
metaverse
It is a new social ecosystem composed of complete and stable technology, content, economy, collaboration and governance subsystems, with the characteristics of high immersion, real-time sustainability, independent creation, open interconnection, etc., and the integration and interaction of virtual and reality
Note: This document is to refine the reference architecture and represents the metaverse as an information system. See Appendix A for the description of each subsystem.
3.2
activity
A collection of a specific set of tasks.
