ISO/IEC TS 22424系列通过双重策略支持EPUB出版物的长期保存。本文件使EPUB符合开放档案信息系统（OAIS）档案的现行做法和存储库系统的技术要求。前者在运作中往往依赖OAI；后者倾向于只在符合METS（元数据编码和传输标准）等标准的容器中接收电子文档。 ISO/IEC TS 22424-1从长期保存的角度考虑EPUB功能。

The ISO/IEC TS 22424 series supports long-term preservation of EPUB publications via a dual strategy. This document makes EPUB compliant with current practices of Open Archival Information Systems (OAIS) archives and technical requirements of repository systems. The former tend to rely on OAIS in their operations; the latter prefer to ingest electronic documents only in containers conforming to standards such as METS (Metadata Encoding and Transmission Standard). ISO/IEC TS 22424-1 considers EPUB features from a long-term preservation point of view.
