Google Calendar

Definition: Application ontology for Google Calendar scheduling platform, modeling events, calendars, attendees, and time management elements.

Parent: Artifact

See also: Gmail, Google Meet, Google Workspace

note

This application ontology is not fully vetted and is subject to changes as we refine the modeling approach for third-party integrations.

Modeling Notes​

  • Google Calendar organizes time-based events across multiple calendar views
  • Events can have complex recurrence patterns and timezone handling
  • Supports multiple calendar types (personal, shared, public, resource calendars)
  • Integration with Gmail enables automatic event creation from emails
  • Meeting rooms and resources can be booked as part of event scheduling

Core Classes​

Calendar Structure​

  • Calendar Account - User's calendar system with multiple calendars
  • Calendar - Individual calendar container for related events
  • Event - Scheduled occurrence with time, location, and participants
  • Recurring Event - Event series with repetition patterns
  • All-Day Event - Events without specific time boundaries
  • Meeting - Events with multiple attendees and collaboration features

Time Elements​

  • Date Time - Specific moment in time with timezone information
  • Time Zone - Geographic time zone for event scheduling
  • Duration - Length of time for events and meetings
  • Recurrence Rule - Pattern defining event repetition
  • Free/Busy Time - Availability information for scheduling
  • Working Hours - Default availability periods

Participant Elements​

  • Attendee - Person invited to or participating in events
  • Organizer - Person who created and manages the event
  • Resource - Bookable items like meeting rooms or equipment
