Extends owl-time ontology (http://www.w3.org/2006/time) with support for several timelines, acting as a backbone to adress time interval/instants. Mainly designed with a multimedia use-case in mind.

Represents a linear and coherent piece of time -- can be either abstract (such as the one behind a score) or concrete (such as the universal time line). Two timelines can be mapped using timeline maps.
An interval (same as in OWL-Time). Allen's relationships are defined in OWL-Time.
Relates an interval or an instant to the timeline on which it is defined. The 29th of August, 2007 would be linked through this property to the universal timeline, whereas "from 2s to 5s on this particular signal" would be defined on the signal' timeline.
refers to a point or an interval on the time line, through an explicit datatype
refers to the end of a time interval, through an explicit datatype. time:hasEnd can be used as well, if you want to associate the end of the interval to an explicit time point resource
refers to the beginning of a time interval, through an explicit datatype. time:hasBeginning can be used as well, if you want to associate the beginning of the interval to an explicit time point resource
An interval defined on an abstract time-line.
Abstract time lines may be used as a backbone for Score, Works, ... This allows for TimeLine maps to relate works to a given performance (this part was played at this time).
This concept expresses that an instant defined on the universal timeline must be associated to a dateTime value
This property links an instant defined on the universal time line to an XSD date/time value
The timeline one can addresss "the 1st of July, 2007"
this is the `universal' time line -- can adress time intervals on it using date/dateTime -- UTC
Describe the relation between a continuous time-line and its sampled equivalent
associates a sample rate value to a uniform sampling map
associates a timeline map to its range timeline
A discrete time line (like the time line backing a digital signal
associates a timeline map to its domain timeline
Semi infinite time line...canonical coordinate system --> adressed through xsd:duration since the instant 0.
Describes the relation between a discrete time line and its windowed equivalent
Describes the relation between a continuous time-line, and a time-line that corresponds to its sampled and windowed equivalent
An instant defined on a discrete timeline
A subproperty of :at, having as a specific range xsd:int
A continuous timeline, like the universal one, or the one backing an analog signal
A "physical" time-line (the universal time line (UTC)) is an instance of this class. Other time zones consists in instances of this class as well, with a "shifting" time line map relating them to the universal time line map.
A timeline map linking a physical timeline to a relative one (originating at some point on the physical timeline)
An interval defined on a discrete timeline, like the one backing a digital signal
A subproperty of :beginsAt, having xsd:int as a range
A subproperty of :endsAt, having xsd:int as a range
A subproperty of :duration, having xsd:int as a range
an interval defined on a relative timeline
A property enabling to adress a start time point P of an interval [P,E] through the duration of the interval [0,P] on a continuous timeline
A subproperty of :duration, having xsd:duration as a range
A property enabling to adress an end time point P of an interval [S,P] through the duration of the interval [0,P] on a continuous timeline
a map just shifting one timeline to another
an interval defined on the universal time line
A subproperty of :at, allowing to address a year (beginning of it for an instant, all of it for an interval)
A subproperty of :at, allowing to address a year/month (beginning of it for an instant, all of it for an interval)
A subproperty of :at, allowing to address a date (beginning of it for an instant, all of it for an interval)
A subproperty of :beginsAt, allowing to address the beginning of an interval as a date/time
A subproperty of :endsAt, allowing to address the end of an interval as a date/time
hop size, associated to a uniform windowing map
window length, associated to a uniform windowing map
An instant defined on a relative timeline
A property enabling to adress a time point P through the duration of the interval [0,P] on a continuous timeline
An instant defined on an abstract timeline
subproperty of :at, having xsd:float as a range
associate a shift map to a particular delay
associate an origin map to its origin on the domain physical timeline
