ISO/IEC 23092-3:2022本文件规定了基因组信息的信息元数据、辅助字段、SAM互操作性、保护元数据和编程接口。它定义:
-ISO/IEC 23092-1（第6条）中规定的不同封装级别的元数据存储和解释
-在ISO/IEC 23092-1（第7条）规定的不同封装级别提供保密性、完整性和隐私规则的保护元素
-如何将辅助字段与编码读取相关联（第8条）
-与现有SAM内容向后兼容的机制，并导出为该格式（见附件C）
-用于访问根据ISO/IEC 23092-1和ISO/IEC 230 92-2（第8.1款）编码的基因组信息的接口。

ISO/IEC 23092-3:2022 This document specifies information metadata, auxiliary fields, SAM interoperability, protection metadata and programming interfaces of genomic information. It defines:
- metadata storage and interpretation for the different encapsulation levels as specified in ISO/IEC 23092-1 (in Clause 6);
- protection elements providing confidentiality, integrity and privacy rules at the different encapsulation levels specified in ISO/IEC 23092-1 (in Clause 7);
- how to associate auxiliary fields to encoded reads (in Clause 8);
- mechanisms for backward compatibility with existing SAM content, and exportation to this format (in Annex C);
- interfaces to access genomic information coded in compliance with ISO/IEC 23092-1 and ISO/IEC 23092-2 (in subclause 8.1).
