The Internet of Musical Things (IoMusT) is an emerging research area consisting of the extension of the Internet of Things paradigm to the music domain. Interoperability represents a central issue within this domain, where heterogeneous objects dedicated to the production and/or reception of musical content (Musical Things) are envisioned to communicate between each other. This paper proposes an ontology for the representation of the knowledge related to IoMusT ecosystems to facilitate interoperability between Musical Things. There was no previous comprehensive data model for the IoMusT domain, however the new ontology relates to existing ontologies, including the SOSA Ontology for the representation of sensors and actuators and the Music Ontology focusing on the production and consumption of music. This paper documents the design of the ontology and its evaluation with respect to specific requirements gathered from an extensive literature review, which was based on scenarios involving IoMusT stakeholders, such as performers and audience members.

音乐物联网（IoMusT）是一个新兴的研究领域，包括将物联网范式扩展到音乐领域。互操作性是该领域内的一个中心问题，其中设想了专用于音乐内容（音乐）的生产和/或接收的异构对象之间进行通信。本文提出了一种用于表示与IoMusT生态系统相关的知识的本体，以促进音乐事物之间的互操作性。IoMusT领域以前没有全面的数据模型，但是新的本体与现有的本体有关，包括代表传感器和执行器的SOSA本体以及专注于音乐生产和消费的Music本体。本文记录了本体的设计及其对从广泛文献回顾中收集到的特定要求的评估，该文献基于涉及IoMusT利益相关者（例如表演者和听众成员）的场景。可以通过以下网址访问IoMusT本体：https：//w3id.org/iomust#。
