Overview
ISO/IEC 23092-5:2020 - Information technology - Genomic information representation - Part 5: Conformance defines how to test and verify conformity of genomic bitstreams and decoders to the format and coding rules in ISO/IEC 23092‑1 and ISO/IEC 23092‑2. The standard specifies a suite of test procedures, identifies the requirements under test, maps requirements to functionality, and supplies electronic test bitstreams and reference verification tools. Note: encoders are not addressed; the focus is on bitstream (file/transport) and decoder (decapsulator) conformity.
Key topics and requirements
- Conformance scope: Procedures for testing file/transport conformity (ISO/IEC 23092‑1) and bitstream/decoder conformity (ISO/IEC 23092‑2).
- Definitions & assumptions: Clarifies terms such as file, transport and decapsulator and states that ISO/IEC 23092‑1 text prevails in any conflict.
- Test procedures: Systematic steps to verify that bitstreams and decoders meet the normative requirements of Parts 1 and 2.
- Test item sets: Predefined test bitstreams grouped by functionality, including:
- Set I: Genome sequencing data with single alignment
- Set II: Quality values
- Set III: Compressed references
- Set IV: Genome sequencing data with multiple alignments
- Support tools & repository: Electronic provision of test bitstreams, a support tool for reference verification, and a conformance repository to store test results and materials.
- Normative references: Directly references ISO/IEC 23092‑1 (transport & storage) and ISO/IEC 23092‑2 (coding).
Practical applications
- Ensures interoperability between genomic data producers, decoders, and analysis tools by validating that bitstreams conform to the ISO/IEC 23092 series.
- Enables vendors and developers to certify decoders/decapsulators for reliable selective data access, dataset decoding, and metadata handling.
- Supports quality assurance and compliance testing in environments handling large-scale sequencing data, including clinical genomics, bioinformatics platforms, and cloud storage services.
- Useful for test labs, standards compliance teams, implementers of ISO/IEC 23092 encoders/decoders, and organizations building genomic data ecosystems.
