Class Property
2 typesschema.org
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](https://schema.org/docs/styleguide.html).
Class Property
2 typesschema.org
Defines the day(s) of the week on which a recurring [Event](https://schema.org/Event) takes place. May be specified using either [DayOfWeek](https://schema.org/DayOfWeek), or alternatively [Text](https://schema.org/Text) conforming to iCal's syntax for byDay recurrence rules.
Class Property
1 typeschema.org
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.
Class Property
1 typeschema.org
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.
Class Property
2 typesschema.org
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.
Class Property
2 typesschema.org
Associates an [Event](https://schema.org/Event) with a [Schedule](https://schema.org/Schedule). There are circumstances where it is preferable to share a schedule for a series of repeating events rather than data on the individual events themselves. For example, a website or application might prefer to publish a schedule for a weekly gym class rather than provide data on every event. A schedule could be processed by applications to add forthcoming events to a calendar. An [Event](https://schema.org/Event) that is associated with a [Schedule](https://schema.org/Schedule) using this property should not have [startDate](https://schema.org/startDate) or [endDate](https://schema.org/endDate) properties. These are instead defined within the associated [Schedule](https://schema.org/Schedule), this avoids any ambiguity for clients using the data. The property might have repeated values to specify different schedules, e.g. for different months or seasons.
Class Property
2 typesschema.org
Defines a [Date](https://schema.org/Date) or [DateTime](https://schema.org/DateTime) during which a scheduled [Event](https://schema.org/Event) will not take place. The property allows exceptions to a [Schedule](https://schema.org/Schedule) to be specified. If an exception is specified as a [DateTime](https://schema.org/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](https://schema.org/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.
Class Property
3 typesschema.org
The identifier property represents any kind of identifier for any kind of [Thing](https://schema.org/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](https://schema.org/docs/datamodel.html#identifierBg) for more details.
Class Property
2 typesschema.org
Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See [background notes](https://schema.org/docs/datamodel.html#mainEntityBackground) for details.
Class Property
2 typesschema.org
Defines the frequency at which [Event](https://schema.org/Event)s will occur according to a schedule [Schedule](https://schema.org/Schedule). The intervals between events should be defined as a [Duration](https://schema.org/Duration) of time.
Class Property
1 typeschema.org
Indicates the timezone for which the time(s) indicated in the [Schedule](https://schema.org/Schedule) are given. The value provided should be among those listed in the IANA Time Zone Database.
Class Property
2 typesschema.org
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.
