Schema.org Event Types
Schema.org Events identifies event format, allowing scheduled conferences and unscheduled developments to be analysed separately.
The date of an information event matters. A planned conference creates anticipation, a fixed disclosure window and a measurable decay path. A delivery, publication, sale or sports event follows a different clock. Schema.org Events supplies compact categories for separating those formats before an event study is specified.[1]
World assigns one of 26 event types to relevant reporting. Researchers can use the field to define scheduled cohorts, align observations to known dates and test whether attention, revisions or price discovery concentrate around the event. The field describes format. It does not identify announcement stage, materiality, surprise or market impact without additional event data, market data and observed returns.

Foundations
Schema.org Events classifies event format without claiming timing, surprise or materiality
Schema.org defines Event as an occurrence at a time and location, with specific types for conferences, business events, publications, broadcasts and other formats. World uses 26 flat, single-label event categories. ConferenceEvent and BusinessEvent are peers. Neither is a parent of the other in the World field.[1][2][3]
The label answers a narrow question: what kind of event is described? It does not encode announcement lifecycle. A GTC keynote can produce conference reporting, product announcements and partner releases. Those records may receive different labels or no Schema.org Event label. Event-time analysis therefore needs an external calendar and an entity-resolved cohort in addition to the ontology and its event-format classification.
Categories
Schema.org Events uses 26 peer categories for scheduled and published event formats
The ontology is flat. Every assigned event receives one peer-level label. The explorer shows each category’s definition, stable code and World V1.2 count. Search keeps all formats accessible on one page. EventSeries identifies a recurring group, but the field does not link individual records into a lifecycle or series instance.[1]
1,010,214 of 15,311,040 World events carry labels from Schema.org Event Types. Select a category to see its count and both relevant shares.

Example usage 1 of 3
Example Usage: Corporate conferences create repeatable information clocks around each scheduled opening keynote day
Ten NVIDIA GTC, Google I/O and AWS re:Invent cycles from 2023 through 2026 produce the same event-time pattern. Nine peak within one day of the opening keynote. Normalized attention rises from 128 events per million English World events during the baseline to 3,669 on keynote day, creating a repeatable disclosure clock.[4][5][6][7][8][9][10][11]
Only 13.4% of assigned records use scheduled ConferenceEvent or BusinessEvent formats. That distinction stops surrounding announcements from masquerading as the conference itself. Researchers can align suppliers, customers and competitors to keynote day, then test volatility, revisions, relative returns and adoption without pooling weeks of unrelated company coverage or inferring an announcement lifecycle from labels alone.[12]
Each line pools repeated conference cycles by event day and divides classified events by all English World events in the same seven-day window. 9 of 10 cycles peak within one day of the keynote. The recurring clock isolates predictable product and platform disclosure windows from unscheduled company news.
Example usage 2 of 3
Example Usage: Prime Day creates a repeatable opening-day signal across three expanding retail cycles
Prime Day creates a repeatable event-time signature across three annual retail cycles. The normalized Schema.org Event rate peaks on the official opening day in 2023, 2024 and 2025. Amazon expanded the 2025 sale from two days to four, yet the classified attention spike remains anchored to the first day of the event.[13]
SaleEvent accounts for 96.1% of assigned events in 2023 and 92.2% in 2025. Normalized assigned coverage rises from 1,011 to 1,614 events per million across those cycles. The category isolates a scheduled commercial demand window that ordinary Amazon mentions mix with products, logistics, advertising and corporate reporting.[14]
- Normalized coverage
- +603 per million
- SaleEvent share
- -3.9pp
- Assigned events
- +78
The English Prime Day cohort uses matched 29-day windows around official opening dates in 2023, 2024 and 2025. Daily Schema.org Event counts are divided by all English World events; the horizontal axis is event day, with zero marking the opening.
Example usage 3 of 3
Example Usage: Eras Tour coverage moves from live concerts into cinemas and streaming
Eras Tour reporting changes event format as the product moves through distribution channels. MusicEvent accounts for 66.1% of assigned events during the live-tour phase. ScreeningEvent reaches 79.4% around the theatrical release. The same property becomes a new research cohort when distribution moves from venues into cinemas.[15]
Streaming creates a third transition. OnDemandEvent reaches 70.6% of assigned coverage in March 2024, when Taylor's Version arrives on Disney+. Schema.org Event categories identify the relevant commercial clock without changing the entity query. Researchers can separate ticket sales, theatrical distribution and subscription engagement without pooling every Eras Tour mention across markets and distribution channels.[16]
- Normalized coverage
- +119 per million
- MusicEvent
- -63.2pp
- ScreeningEvent
- +76.0pp
The explicit English Eras Tour cohort spans March 2023 through April 2024. Monthly shares use Schema.org Event-assigned records; normalized phase rates divide assigned events by all English World events in the same months for direct comparison.
