The Moving Picture Experts Group (MPEG) is an International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) working group that develops media coding standards. These standards include a set of ontologies for the codification of intellectual property rights (IPR) information related to media. The Media Value Chain Ontology (MVCO) facilitates rights tracking for fair, timely, and transparent payment of royalties by capturing user roles and their permissible actions on a particular IP entity. The Audio Value Chain Ontology (AVCO) extends MVCO functionality related to the description of IP entities in the audio domain, e.g., multitrack audio and time segments. The Media Contract Ontology (MCO) facilitates the conversion of narrative contracts to digital ones. Furthermore, the axioms in these ontologies can drive the execution of rights-related workflows in controlled environments, e.g., blockchains, where transparency and interoperability is favored toward fair trade of music and media. Thus, the aim of this article is to create awareness of the MPEG IPR ontologies developed in the last few years and the work currently taking place addressing the challenge identified toward the execution of such ontologies as smart contracts on blockchain environments.

挑战：从 MPEG 知识产权本体到智能合约和区块链 [标准简述]

运动图像专家组 (MPEG) 是一个国际标准化组织/国际电工委员会 (ISO/IEC) 工作组，负责开发媒体编码标准。这些标准包括一组用于编纂与媒体相关的知识产权 (IPR) 信息的本体论。媒体价值链本体 (MVCO) 通过捕获用户角色及其对特定 IP 实体的许可行为，促进权利跟踪，以实现公平、及时和透明的版税支付。音频价值链本体 (AVCO) 扩展了与音频域中 IP 实体描述相关的 MVCO 功能，例如多轨音频和时间段。媒体合同本体（MCO）促进了叙事合同向数字合同的转换。此外，这些本体中的公理可以推动在受控环境（例如区块链）中执行与权利相关的工作流，其中透明度和互操作性有利于音乐和媒体的公平贸易。因此，本文的目的是提高人们对过去几年开发的 MPEG IPR 本体的认识，以及目前正在进行的工作，以解决在区块链环境中执行智能合约等本体所面临的挑战。
