  1. AKN and Node Data Architecture Draft 7 June 8, 2009

  2. The Avian Knowledge Network

  3. USER PARTNER Covariates Taxonomies Observations Geography Metadata Events PROVIDER AKN Node Architecture Data Services (DiGIR) Node Node Data Warehouses Data Access Data Analysis Data Publishing Access Control Data Visualization Data Entry Data Processing Node Data Store (NodeDb) = data store = process or application = data flow

  4. NodeDb USER USER PARTNER PARTNER PROVIDER Node Architecture and NodeDb Node Lists, counts, surveys banding records, nest data, etc… Bulk Data Process Data Analysis Data Entry Data Retrieval Avian Ecology Observations segregated by source (A, B, C..)

  5. How NodeDb Codifies Observations Why? Project /Protocol/Researcher defined in How? Who? has many Sampling Units Where? has many Sampling Events When? has many Sampling Observations What recorded?

  6. NodeDb Major Data Components Protocols defines methodology for Projects Sampling Units Sampling Events is located at contains participates in consisting of Researchers Sampling Event Observations collects uses Taxonomy
