The global Covid-19 pandemic has been accelerating the transition to the digital environment that enables providing consistent services without being affected by physical location or various circumstances. The Metaverse might be the representative realization reflecting this trend. In this paper, we introduce the potential core stacks consisting of the Metaverse framework in brief and explain why the open Metaverse framework is an adequate and reasonable design choice to support diverse platforms and multiple instances of the virtual world. Since the development of the open Metaverse framework is indeed in a very early stage, achieving technical completeness in each building block of the open Metaverse is crucial. Considering the expansion and spread of the Metaverse in the future, intensive standardization studies on the open Metaverse framework are exigent and indispensable.
