Genomic Standards Consortium (GSC)

Goal

• Promote mechanisms that standardize the description of genomes

exchange and integrate genomic data

Open-membership, international working body

• Established in Sept 2005

• Participants include DDBJ, EMBL, GenBank, Sanger, JCVI, JGI, EBI and a range of US, UK and EU research institutions

• Organized a series of workshops

Minimum Information about a Genome Sequence(MIGS) Specification

MIGS extends what DDBJ/EMBL/GenBank request upon submission of a genome sequence

• Examples:

Description of geographic location of a sample and habitat

“Minimum Information about a Metagenomic Sequence” (MIMS)

– Temperature

– pH

Description of sequence generation– Sequencing method

– Assembly method

Software Development for MIGS/MIMS

Mechanisms for achieving compliance are needed:

• Such mechanisms involve an appropriate reporting

structure for capturing and exchanging data,

software,

databases

and controlled vocabularies and/or ontologies for defining the terms used in the annotations.

Habitat-Lite (= EnvO-Lite)

Easy-to-use (small) set of terms

• Captures high-level information about habitat

• Derived from the Environment Ontology (EnvO).

Meet the needs of multiple users

• Annotators, database providers, biologists, and bioinformaticians alike who need to search and employ such data in comparative analyses.

Create a unified mapping between different genomic

resources

Improve navigation across these resources

Enable the integration of this information in the near

future.

Genomic Contextual DataMarkup Language (GCDML)

An Extensible Markup Language (XML)

Aim

• Implement MIGS/MIMS

• Provide even more descriptors

• Facilitate exchange and integration of genomic data

Genome Catalogue

Online system for capturing MIGS/MIMS compliant

reports

21Field et al. Nature 2008

22

Genome Catalogue

Requirements

• A Rich toolkit/user-friendly

• Designed to give credit to all contributors

• XML-based (GCDML) Able to maintain all versions of GCDML schemas

• Web services-based Supporting the automated exchange of content

• Serve as the international GCAT identifier authority

• Comprehensive Containing reports for all taxa and metagenomes

• Ontology-supportive

• Shared by the GSC

22

23

Current Status

We have specifications:

• MIGS/MIMS

• Habitat-Lite

• Genomic Rosetta Stone

Work on supporting software is ongoing:

• Genomes Catalogue is in prototype status

• Funding This is a long-term endeavour that can not be done on a

voluntary basis

23

24

Disscusion

Need of software for:

• Creation of MIGS/MIMS data

• Storage

• Analysis

Expand standardization efforts to

• Software specification/development

• Work on a standardized genomic data management architecture / cyberinfrastructure

Data intensive science is successful if it works

towards one community with one vision

• World Wide Genomics project
