EventHost
RIXML 2.5 Element
Container identifying organizations hosting research-related events. Supports multiple hosting organizations with designation of a single primary host through Organization primaryIndicator attribute.
Describes the organization hosting the event. Multiple hosts of one event are possible. However, there can be only one primary host, which is captured by the Organizatoin primaryIndicator.
Usage
Contains one or more Organization elements when events involve multiple hosting entities. Required to identify at least one primary host, with additional co-hosts marked as non-primary.
Business Context
Critical for event management and attendee coordination. Helps research consumers identify event authority and contact appropriate parties for participation, sponsorship, or logistical information.
Specification Guide
Overview
EventHost identifies the organization or organizations responsible for hosting or organizing an event that is the subject of a research product. It is a container element appearing within EventDetails that holds one or more Organization elements, supporting both single-host and co-hosted events while enabling designation of a single primary host (sources: data-dictionary-2.4 p.44, data-dictionary-2.5.1 p.47, user-guide-2.3 p.32). By capturing event ownership, it allows research consumers to understand the authoritative source and credibility of event-based information and to route registration or logistical inquiries to the appropriate party.
Usage
EventHost is an optional child of EventDetails. When present, it must contain at least one Organization element, with multiples permitted to describe co-hosted or jointly sponsored events (sources: data-dictionary-2.4 p.44, user-guide-2.3.1 p.32). When more than one Organization is supplied, exactly one should be designated as the primary host using the primaryIndicator attribute (in v3 drafts this is referred to as isPrimary) (sources: user-guide-2.3 p.32, data-dictionary-v3-draft p.78). Typical use cases include conferences, roadshows, analyst days, and other corporate or financial events being covered in the research product.
Rules
- MUSTWhen multiple Organization elements are present within EventHost, only one may be marked as the primary host via primaryIndicator (named
isPrimaryin v3 drafts).[RIXML User Guide v2.3 p.32] [RIXML Research Suite Data Dictionary v3.0 (DRAFT) p.78]↗ - INFORMATIVEEventHost, together with the rest of the EventDetails sub-structure, is a candidate for removal in RIXML v3.0 because it is not being used by publishers or expected by research portals; implementers should treat its long-term inclusion as uncertain.[RIXML All-Member Meeting June 2023 p.33]↗
Relationships
- contained-byEventDetails — EventHost appears as an optional child of EventDetails, providing the hosting-organization dimension of an event description alongside siblings such as EventVenue and EventDate.
- containsOrganization — EventHost contains one or more Organization elements identifying each hosting entity. In the v3 draft this aggregation is represented via an OrganizationList wrapper.
- constrained-byOrganization.primaryIndicator — primaryIndicator (or
isPrimaryin v3) constrains EventHost such that at most one contained Organization is identified as the primary host.

Unchanged since introduction in RIXML 2.1
EventHost is documented consistently from RIXML 2.3 through 2.5.1 as an optional child of EventDetails containing one or more Organization elements, with the primary host designated through primaryIndicator (sources: user-guide-2.3 p.32, user-guide-2.3.1 p.32, data-dictionary-2.4 p.44, data-dictionary-2.5.1 p.47). The v3.0 draft retains the element semantically but restructures the contained organizations into an OrganizationList aggregation and renames the primary-host flag to isPrimary [data-dictionary-v3-draft p.78]. A June 2023 working-group meeting proposed removing the entire EventDetails sub-structure — including EventHost — from v3.0 on the grounds that it is not used by publishers or expected by research portals [meeting-2023-06 p.33]; implementers should monitor the final v3.0 schema to confirm whether the element survives.
