Schedule

A schedule defines a repeating time period used to describe a regularly occurring Event. At a minimum a schedule will specify repeatFrequency which describes the interval between occurrences of the event. Additional information can be provided to specify the schedule more precisely. This includes identifying the day(s) of the week or month when the recurring event will take place, in addition to its start and end time. Schedules may also have start and end dates to indicate when they are active, e.g. to define a limited calendar of events.

Properties

13 of its own, and 14 it inherits. Each says what kind of value it takes.

Its own13
PropertyValueWhat it means
byDayValue: DayOfWeek or Text

Defines the day(s) of the week on which a recurring Event takes place. May be specified using either DayOfWeek, or alternatively Text conforming to iCal's syntax for byDay recurrence rules.

byMonthValue: Integer

Defines the month(s) of the year on which a recurring Event takes place. Specified as an Integer between 1-12. January is 1.

byMonthDayValue: Integer

Defines the day(s) of the month on which a recurring Event takes place. Specified as an Integer between 1-31.

byMonthWeekValue: Integer

Defines the week(s) of the month on which a recurring Event takes place. Specified as an Integer between 1-5. For clarity, byMonthWeek is best used in conjunction with byDay to indicate concepts like the first and third Mondays of a month.

durationValue: Duration or QuantitativeValue

The duration of the item (movie, audio recording, event, etc.) in ISO 8601 duration format.

endDateValue: Date or DateTime

The end date and time of the item (in ISO 8601 date format).

endTimeValue: DateTime or Time

The endTime of something. For a reserved event or service (e.g. FoodEstablishmentReservation), the time that it is expected to end. For actions that span a period of time, when the action was performed. E.g. John wrote a book from January to December. For media, including audio and video, it's the time offset of the end of a clip within a larger file.

Note that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.

exceptDateValue: Date or DateTime

Defines a Date or DateTime during which a scheduled Event will not take place. The property allows exceptions to a Schedule to be specified. If an exception is specified as a DateTime then only the event that would have started at that specific date and time should be excluded from the schedule. If an exception is specified as a Date then any event that is scheduled for that 24 hour period should be excluded from the schedule. This allows a whole day to be excluded from the schedule without having to itemise every scheduled event.

repeatCountValue: Integer

Defines the number of times a recurring Event will take place.

repeatFrequencyValue: Duration or Text

Defines the frequency at which Events will occur according to a schedule Schedule. The intervals between events should be defined as a Duration of time.

scheduleTimezoneValue: Text

Indicates the timezone for which the time(s) indicated in the Schedule are given. The value provided should be among those listed in the IANA Time Zone Database.

startDateValue: Date or DateTime

The start date and time of the item (in ISO 8601 date format).

startTimeValue: DateTime or Time

The startTime of something. For a reserved event or service (e.g. FoodEstablishmentReservation), the time that it is expected to start. For actions that span a period of time, when the action was performed. E.g. John wrote a book from January to December. For media, including audio and video, it's the time offset of the start of a clip within a larger file.

Note that Event uses startDate/endDate instead of startTime/endTime, even when describing dates with times. This situation may be clarified in future revisions.

From Thing14
PropertyValueWhat it means
additionalTypeValue: Text or URL

An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org style guide.

alternateNameValue: Text

An alias for the item.

descriptionValue: Text or TextObject

A description of the item.

digital.org.aiValue: Number

Digital maturity score from 0.0 (fully analog/manual) to 1.0 (fully digital/autonomous). Indicates the degree to which an entity operates digitally.

disambiguatingDescriptionValue: Text

A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.

identifierValue: PropertyValue, Text or URL

The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.

imageValue: ImageObject or URL

An image of the item. This can be a URL or a fully described ImageObject.

mainEntityOfPageValue: CreativeWork or URL

Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.

nameValue: Text

The name of the item.

ownerValue: Organization or Person

A person or organization who owns this Thing.

potentialActionValue: Action

Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.

sameAsValue: URL

URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website.

subjectOfValue: CreativeWork or Event

A CreativeWork or Event about this Thing.

urlValue: URL

URL of the item.
