Genomic Information Representation

Editions

Edition - 1: Genomic Information Representation

Publication Year: 0
Status: released
Motivations: The development of Next Generation Sequencing (NGS) technologies enable the usage of genomic information as everyday practice in several fields, but the growing volume of data generated becomes a serious obstacle for a wide diffusion. The lack of an appropriate representation and efficient compression of genomic data is widely recognized as a critical element limiting its application potential. ISO/TC 276 and MPEG have combined their respective expertise and missions to develop a compression standard capable of providing new effective solutions for genomic information processing applications
Objectives: The objectives of the standard are to provide:\r\n- A transport format specification that supports a file format for storage scenarios and a packet format for streaming scenarios that are mutually convertible.\r\n- A compressed representation for sequence reads, quality values and alignment information that enable efficient selective access to genomic regions, data classes and associated information.\r\n- Standard APIs for selective access to the compressed genomic information and the conversion to and from MPEG-G files of commonly used genomic data formats.\r\n- Reference SW for the normative decoding process and informative encoding, conformance methodology.

Edition - 2: Genomic Information Representation

Publication Year: 0
Status: released
Motivations: Errors in the first edition were identified.
Objectives: Provide a clean second edition.

Edition - 2: Extensions and Improvements to ISO/IEC 23092 series

Publication Year: 0
Status: released
Motivations: Improve performance of entropy coding by adding alternative entropy coding methods for sequencing data and annotation data.
Objectives: Improve performance (speed) of entropy coding for sequencing data. being able to select the most appropriate entropy coding method for annotation data. Introduce indexing capabilities in the compressed domain for string based sequence data and annotations.
