# G39 Event, venue, organizer, and time graph

## Question

Which real event occurs when and where, and who organizes it?

## Nodes

Event occurrence; Series; Venue; Organizer; Performer; Offer

## Relationship sketch

* occurrence → venue/time
* occurrence → organizer
* series → actual occurrences

## Evidence inputs

Actual event announcements, schedules, organizers, cancellations, venue facts, and ticket details.

## Implementation

Track occurrences and status changes rather than treating a recurring event as one eternal date. Keep online locations, venues, and organizers distinct.

## Acceptance checks

* Dates and time zones match approved announcements
* Cancelled or rescheduled status is retained
* The page actually represents an event eligible for the selected feature

## Do not infer

An organization's ordinary opening hours are not automatically an eligible Event.

## Publication boundary

Approved event information public.

## Source basis
