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).
