    • The role of grass-roots data sharing communities, standards and megasequencing projects in the genomics revolution Dawn Field NERC Centre for Ecology and Hydrology  
    • Opportunities and Challenges
      • The era of genomics is just beginning...
      • ...how will we cope with the data?
      • ...how will we gain the most knowledge from this investment in data?
    • PARADIGM SHIFT Nikos Kyrpides 1960-1990 16S RNA 1990-2010 Genomes 2010-2020 Pangenomes
    • GREAT CHALLENGES P. Chain et al. Science, 2009 Nikos Kyrpides 1995-2009 2010-2015 Finished 1000 3000 Draft 1000 10000
    •  
    • Nikos Kyrpides Culturable Unculturable
    • The trend is now increasingly geared towards ever more ambitious megasequencing projects...
    •  
    • And democratization of access to sequencing power... Just one example....
    • (~80) 41 metagenomes “ Global Ocean Survey” Sanger sequencing (Rusch et al, 2007) Metagenomics: Putting data generating capacity into perspective with an example from Bergen (1) 1 metagenome Sargasso Sea Sanger sequencing (Venter et al, 2005) (~120) 4 metagenomes & 4 metatranscriptomes Bergen mesocosm experiment Pyrosequencing (Gilbert et al, 2008) Gilbert JA, Field D, Huang Y, Edwards R, Li W, Gilna P, Joint I. (2008) Detection of large numbers of novel sequences in the metatranscriptomes of complex marine microbial communities. PLoS ONE. Aug 22;3(8):e3042.
    • The Bergen ocean acidification study produced 19% of the reads produced in the GOS study and 5% of the total basepairs of sequence. Further evidence for the “Unknown Genome” and the Dark Matter of the Tree of Life
    • The Data - Flood - Tsunami - Deluge ?
    • the data bonanza
    • To exploit fully the promise of these data we need both scientific innovation and community agreement on how to provide appropriate stewardship of these resources for the benefit of all.   Requires the evolution of our scientific, technological and sociological thinking....
    • SuperMarket The Genome Catalogue
    • DataMarket Norman Morrison
    • Packaging data
    • Labels for data <phenotype> <environmental context>
      • Principles :
      • Not everything should be ‘standardized’
      • Aggregation of data, information, and knowledge requires
      • standard ways of doing things
      • Standards provide foundations; Standards should drive innovation
      • (think of electrical plugs or the internet)
      • Pick the right concepts to standardize – at the right time, with
      • the right people
      • Requires good ‘group think’ – or ‘systems thinking’
      standards
      • Community-driven solutions:
      • The Common Path:
        • Identify the problem
        • Define a community to address it
        • Define scope of the solution
        • Implement solution
        • Gain adoption of solution
    • The Genomic Standards Consortium GSC 10 Argonne, 2010 GSC 11, Hinxton, 2010 Innovation through Collaboration GSC 12 Bremen, 2011 GSC 13 BGI 2012
    • The GSC’s Mission
      • the implementation of new genomic standards
      • methods of capturing and exchanging metadata
      • harmonization of metadata collection and analysis efforts across the wider genomics community
    • The GSC fulfills its mission by
      • Organizing meetings
      • Forming working groups
      • Creating Consensus Products
    • Pelin Yilmaz et al 2011
    •  
    • Use of MIGS/MIMS/MIENS
      • Please provide this minimum information when you publish
          • a genome
          • a metagenome
          • a gene marker study (i.e. ribosomal genes)
      • Genbank, EMBL and DDBJ now accept this information and encourage its submission to their public DNA databases
    • Labels for data <MIGS> <MIMS>
    •  
    • Goal: International effort to sequence a reference genome for every cultured Archaeal and Bacterial organism (~9,000 microbes ) The Microbial Earth Project Phase I: Sequence one representative from every characterized microbial type species GEBA HMP

    • Field et al unpublished work on a Metadata Coverage Index (MCI) MCI > 50
    • GSC 5 at the EBI 2008

    • Incentives for compliance
    • MIGS compliant marine phage genomes
    • GSC 9 at the JCVI – April 2010

    • Darwin Core GSC MIxS Peter Dawyndt Darwin core vs GSC MixS standard
    • Darwin Core GSC MIxS standard Taxon Identification Occurrence IPR related info Event Location GeologicalContext SamplingProtocol EnvironmentalConditions Darwin core vs GSC MixS standard Peter Dawyndt
    • Preliminary (first) conclusions
      • DC & GSC checklist more complementary than overlapping
        • how can we make these standards completely orthogonal?

      • 1) Pick terms
      • 2) View hits
      • 3) Browse
      • 4) Follow links to primary data
      – building on ontologies Users : http://ontogrator.org Morrison et al, 2011 SIGS
      • Ontogrator approach depends on quality of
      • Data Resources
      • Knowledge Organization Systems (KOS) used
      • Can we use this approach to improve both?
      • Can we complete the virtuous cycle?

    • Conclusions
      • The era of genomics is just beginning…
      • Self-organization by the scientific community can pay dividends (i.e. consensus building, large-scale co-ordination)
        • Standards are keys to unlocking data
        • Group thinking overcomes the tragedy of the commons
      • Emerging key players from the molecular domain – “one stop shops”
        • Genomic Standards Consortium
        • BioSharing – driving cross-community collaborations
    • Feast of the Mind
    • Future
      • Analysis – proof sharing is beneficial
      • Making the field of data sharing more quantitative
        • Objective measures of consensus
        • Useful Metrics: i.e. Metadata coverage index (MCI)
        • Modelling – i.e. how to best incentivize data sharing?
      • Further shared concepts
        • Minimum Information about a Sampling Site (MISS)
        • Minimum Data Policy
        • PubData?
