3. Relationships
The relationships object of an event resource MUST contain the following fields:

Contributors do not include those attending the event. Nullable. Non-empty. -
multimediaDescriptions: a basic-resource-schema.adoc#anchor-referencetomany media object resources (see Media Objects) that are related to the event. See Section basic-resource-schema.adoc#anchor-multimediadescriptions. Nullable. Non-empty. -
organizers: a basic-resource-schema.adoc#anchor-referencetomany agent resources (see Agents) identifying the persons or organizations responsible for organizing the event. Non-nullable. Non-empty. -
publisher: a basic-resource-schema.adoc#anchor-referencetoone agent resource (see Agents) who originally provided the data about the event. The publisher is not the organization who manages the system where the data was originally inserted, but the organization actually provided the data. Non-nullable. -
series: a basic-resource-schema.adoc#anchor-referencetoone event series resource (see Event Series) of which the event is an edition of. For instance, the Südtirol Jazz Festival 2020 is an edition of the Südtirol Jazz Festival. Nullable. -
sponsors: a basic-resource-schema.adoc#anchor-referencetomany agent resources (see Agents) identifying the persons or organizations who are sponsoring the event. Nullable. Non-empty. -

For instance, a festival may consist of several concerts and a conference may consist of several presentations and a keynote. Nullable. Non-empty.There SHALL NOT be a circular composition of events. For instance, if X is a sub-event of Y, and Y is a sub-event of Z, Z SHALL NOT be a sub-event of X.
Note that sub-events are not restricted to the temporal boundaries of their parent events. For instance, a conference that starts on 15/03/2020 and ends on 20/03/2020 may have, as a sub-event, a pre-conference meeting that is scheduled for the 14/03/2020.
