Existing metaverse systems lack rich relation types between entities and events. The challenge is that there is no portable framework to introduce rich concepts, relations, events into the metaverse. This paper introduces a new metaverse framework, MetaOnce. This framework proposes to build multi-scene graphs. This framework not only describes rich relations in a single scene but also combines multiple scene graphs into a complete graph for more comprehensive analysis and inference. Prior social network systems mainly describe friend relations. They ignore the effect of entity-relation-event games on the metaverse system and existing rule constraints. We propose a rule controller and impose constraints on the relations that allow the framework to behave in a compliant manner. We build a metaverse system to test the features of the framework, and experimental results show that our framework can build a multi-scene metaverse with memory and rule constraints.

本文提出了一个名为MetaOnce的新型元宇宙框架，通过建立多场景图，描述实体之间的丰富关系，同时还能将多个场景图结合成一个完整图进行更全面的分析和推理，并引入了规则控制器和关系约束，以使该框架能够以合规方式运行。我们构建了一个元宇宙系统来测试该框架的功能，实验结果表明，我们的框架可以构建具有记忆和规则约束的多场景元宇宙。
