      • currentPublishedVersionId: versionId
      • draftVersionId: versionId
    • SurveyVersion
      • surveyId: hashkey (unique to each survey version)
      • versionId: rangeKey (string representing a number an iso timestamp)
      • questions: JSON (surveyjs data)
  • GraphQL API
    • Objects
      • Survey object
        • id - uuid
        • title
        • ownerId
        • currentPublishedVersionId
        • draftVersionId
        • currentPublishedVersion => SurveyVersion object
        • draftVersion => SurveyVersion object
        • versions => list of survey versions
      • SurveyVersion object
        • surveyId
        • versionId
        • questions
    • Query
      • survey(id)- gets a survey
      • surveys(state: ‘published’ | ‘draft’ |’all’ ) - all surveys
    • Mutations
      • saveSurvey
        • If id provided, then create Survey and SurveyVersion (new draft)
        • Otherwise, provide id => saved questions overwrite draft SurveyVersion
      • publishSurvey (surveyId)
      • deleteSurvey
      • unpublishSurvey (surveyId) ? - not yet
