    Cdao Obo Workshop 2010 (3) Cdao Obo Workshop 2010 (3) Presentation Transcript

    • Comparative Data Analysis Ontology
    • History
      • Beginnings
        • CDAO grew out out the Evolutionary Informatics Working Group
        • A primary objective was to formalize the concepts and relationships important to comparative analysis
      • Recent Publications/Events
        • Initial Implementation of a Comparative Data Analysis Ontology. Evolutionary Bioinformatics. (July 2-09)
        • Nescent Database Interoperability Hackathon (March 2009)
        • TDWG 09 VoCamp (November 2009)
      • Statistics
        • CDAO Defines
          • 76 Classes
          • 61 Object Properties
          • 10 Datatype Properties
    • Design Overview
      • CDAO is organized around three key concepts
        • Character-State Data Matrix
        • Tree
          • Includes rooted, unrooted, and networks.
        • Data type
          • Categorical
            • Molecular
              • DNA, RNA, Amino-Acids.
            • Standard
              • which includes any categorical data, it's intended as an alignment point for specific categories that a researcher would define.
          • Continuous
    • CDAO Organization
    • Curret/Future Work
      • Triple-store
        • A triple-store containing CDAO versions of TreeBase data has been created.
        • The store supports storing arbitrary related rdf
        • The store allows users to upload files in NEXUS, PHILIP and MEGA formats (NEXML support is in progress)
        • The store has a SparQL interface
        • Currently a higher-level query interface is being developed to enhance usability and support queries that can not be handled with SparQL.
      • MIAPA (Minimum Information About a Phylogenetic Analysis)
        • Extend the set of extra annotations to facilitate use with a workflow/provenance framework.
        • Integrate/Align CDAO with other related standards efforts.
