val time_ : string -> Iri.t
val c_DateTimeDescription : Iri.t

Description of date and time structured with separate values for the various elements of a calendar-clock system. The temporal reference system is fixed to Gregorian Calendar, and the range of year, month, day properties restricted to corresponding XML Schema types xsd:gYear, xsd:gMonth and xsd:gDay, respectively.

val c_DateTimeInterval : Iri.t

DateTimeInterval is a subclass of ProperInterval, defined using the multi-element DateTimeDescription.

The day of week

val c_Duration : Iri.t

Duration of a temporal extent expressed as a number scaled by a temporal unit

val c_DurationDescription : Iri.t

Description of temporal extent structured with separate values for the various elements of a calendar-clock system. The temporal reference system is fixed to Gregorian Calendar, and the range of each of the numeric properties is restricted to xsd:decimal

val c_GeneralDateTimeDescription : Iri.t

Description of date and time structured with separate values for the various elements of a calendar-clock system

val c_GeneralDurationDescription : Iri.t

Description of temporal extent structured with separate values for the various elements of a calendar-clock system.

val c_Instant : Iri.t

A temporal entity with zero extent or duration

val c_Interval : Iri.t

A temporal entity with an extent or duration

val dt_Number : Iri.t

Note: integer is a specialization of decimal

val c_ProperInterval : Iri.t

A temporal entity with non-zero extent or duration, i.e. for which the value of the beginning and end are different

val c_TRS : Iri.t

A temporal reference system, such as a temporal coordinate system (with an origin, direction, and scale), a calendar-clock combination, or a (possibly hierarchical) ordinal system.

This is a stub class, representing the set of all temporal reference systems.

val c_TemporalEntity : Iri.t

A temporal interval or instant.

val c_TemporalUnit : Iri.t

A temporal unit of measure, which provides a scale factor for a time quantity.

val c_TimePosition : Iri.t

A temporal position described using either a (nominal) value from an ordinal reference system, or a (numeric) value in a temporal coordinate system.

val c_Year : Iri.t

Duration year, not a calendar year!

val after : Iri.t

Gives directionality to time. If a temporal entity T1 is after another temporal entity T2, then the beginning of T1 is after the end of T2.

val before : Iri.t

Gives directionality to time. If a temporal entity T1 is before another temporal entity T2, then the end of T1 is before the beginning of T2. Thus, before can be considered to be basic to instants and derived for intervals.

val day : Iri.t

Day position in a calendar-clock system.

val dayOfWeek : Iri.t

The day of week, whose value is a member of the class time:DayOfWeek

val dayOfYear : Iri.t

The number of the day within the year

val days : Iri.t

length of a temporal extent expressed in days

val dt_generalDay : Iri.t

Day of month - generalization of xsd:gDay, formulated as a text string with a pattern constraint to reproduce the same lexical form as gDay, except that values up to 99 are permitted, in order to support calendars with more than 31 days in a month. Note that the value-space is not defined, so a generic OWL2 processor cannot compute ordering relationships of values of this type.

val dt_generalMonth : Iri.t

Month of year - generalization of xsd:gMonth, formulated as a text string with a pattern constraint to reproduce the same lexical form as gMonth, except that values up to 20 are permitted, in order to support calendars with more than 12 months in the year. Note that the value-space is not defined, so a generic OWL2 processor cannot compute ordering relationships of values of this type.

val dt_generalYear : Iri.t

Year number - generalization of xsd:gYear, formulated as a text string with a pattern constraint to reproduce the same lexical form as gYear. Note that the value-space is not defined, so a generic OWL2 processor cannot compute ordering relationships of values of this type.

val hasBeginning : Iri.t

Beginning of a temporal entity.

val hasDateTimeDescription : Iri.t

Value of DateTimeInterval expressed as a structured value.

val hasDuration : Iri.t

Duration of a temporal entity, expressed as a scaled value or nominal value

val intervalDuring : Iri.t

If a proper interval T1 is intervalDuring another proper interval T2, then the beginning of T1 is after the beginning of T2, and the end of T1 is before the end of T2.

val intervalEquals : Iri.t

val intervalFinishedBy : Iri.t
