3. High Throughput Sequencing Enabling technology – Epidemiology of outbreaks – Pathogen evolution – Host range restriction – Genetic determinants of virulence and pathogenicity Metadata requirements – Temporal-spatial information about isolates – Selective pressures – Host species of specimen source – Disease severity and clinical manifestations

4. Metadata Submission Spreadsheets 1111 2 2 3 3 4 44

5. Complex Query Interface

6. Metadata Inconsistencies Each project was providing different types of metadata No consistent nomenclature being used Impossible to perform reliable comparative genomics analysis Required extensive custom bioinformatics system development

7. GSC-BRC Metadata Standards Working Group NIAID assembled a group of representatives from their three Genome Sequencing Centers for Infectious Diseases (Broad, JCVI, UMD) and five Bioinformatics Resource Centers (EuPathDB, IRD, PATRIC, VectorBase, ViPR) programs Develop an approach for capturing standardized metadata for pathogen isolate sequencing projects Bottom up approach to capture data considered to be important by users Compatible with data standards and submission requirements

8. Metadata Standardization Process Collect example metadata sets from sequencing project white papers and other project sources (e.g. CEIRS) Identify data fields that appear to be common across projects and samples (core) and data fields that appear to be pathogen or project specific For each data field, provide common set of attributes, including preferred term, definition, synonyms, allowed value sets preferably using controlled vocabularies, expected syntax, etc. Assemble all metadata fields into a semantic network based on the Ontology of Biomedical Investigation (OBI) Compare, map, and harmonize to other relevant initiatives, including Genome Standards Consortium MIxS and NCBI BioProjects/BioSamples Draft data submission spreadsheets Beta test version 1.0 standard with new GSCID white paper projects, collecting feedback Adopt version 1.1 metadata standard and data submission spreadsheets for all GSCID white paper and BRC-associated projects

13. Core Project Semantics

14. Outcome of Metadata Standards WG Consistent metadata captured across GSCID Bottom up approach focuses standard on important features Support more standardized BRC interface development Harmonization with related stakeholders – Genome Standards Consortium MIxS, OBO Foundry OBI and NCBI BioProject/BioSample Represented in the context of an extensible semantic framework

15. Identified gaps in data field list (e.g. temporal components) Includes logical structure for other, project-specific, data fields - extensible Identified gaps in ontology data standards (use case- driven standard development) Identified commonalities in data structures (reusable) Support for semantic queries and inferential analysis in future Ontology-based framework is extensible – Sequencing => “omics” Utility of semantic representation
