        • a calendar month is not a definite quantity
        • a calendar week is not a definite quantity because of leap seconds

    • completed reconciliation except for one item
    • lots of work applying comments and profiles
    • bindings
      • strength of recommendation
      • quality of evidence
      • GRADE is an example, but there are many others
      • cannot require GRADE
      • can you flag the top level recommendations of different systems?  
        • not reliably, since different criteria would be used
      • individual implementations could specify specific systems
      • discussion of example versus preferred binding
        • consensus formed around it being an example
        • when you create an instance, you have to make a selection
  • EBM-on-FHIR Update - Brian Alper
    • COVID-19 Knowledge Accelerator (COKA) project
      • extension of EBM-on-FHIR
      • goal: establish FHIR standards for various aspects about evidence about COVID-19
      • a primary effort was on the Citation resource
      • although there's a concept of relatedArtifact, the large volume of citations to be shared and de-duplicated required a different approach
      • citation managers - demonstrate they can send, receive data in this format
      • EvidenceReport resource
        • purpose - transmit combinations of data; it's a composition
        • use cases
          • classification - citation is about treatment, a certain type of study, about human Covid-19 disease
          • search results - list of search results
          • resource compilation - contains one or more other FHIR resources
          • structured text
        • divided into sections
