description: >-
  Entity-relationship graph derived from the schemas and path structure of the
  Office 365 / Microsoft Graph subset in this repo (Outlook mail, OneDrive files,
  Teams). Relationships are inferred from $ref links and path nesting; id-prefix
  detail is not published by Graph (opaque ids).
entities:
  - name: User
    key: id
    note: The signed-in user (/me); root of most navigation.
  - name: Message
    key: id
    schema: "#/components/schemas/Message"
    fields: [id, subject, bodyPreview, from, toRecipients, receivedDateTime]
  - name: MailFolder
    key: id
    note: Container of messages (/me/mailFolders)
  - name: Drive
    key: id
    schema: "#/components/schemas/Drive"
    fields: [id, driveType, owner, quota]
  - name: DriveItem
    key: id
    schema: "#/components/schemas/DriveItem"
    fields: [id, name, size, file, folder, createdDateTime, lastModifiedDateTime]
  - name: Team
    key: id
    note: A Microsoft Teams team (/teams/{team_id})
  - name: Channel
    key: id
    note: A channel within a team
  - name: ChatMessage
    key: id
    note: A message within a channel
relationships:
  - {from: User, type: has_many, to: Message, via: /me/messages}
  - {from: User, type: has_many, to: MailFolder, via: /me/mailFolders}
  - {from: User, type: has_one, to: Drive, via: /me/drive}
  - {from: User, type: has_many, to: Team, via: /me/joinedTeams}
  - {from: MailFolder, type: has_many, to: Message, via: messages}
  - {from: Drive, type: has_many, to: DriveItem, via: root/children}
  - {from: DriveItem, type: has_many, to: DriveItem, via: children (folder nesting)}
  - {from: Team, type: has_many, to: Channel, via: channels}
  - {from: Channel, type: has_many, to: ChatMessage, via: messages}
notes:
  - Microsoft Graph ids are opaque, service-assigned strings; no documented id-prefix scheme.
