An observation of the annotation, understood as an event defined in time (both real and symbolic) that has a value (e.g. a specific agreement) and a precise duration.

• JAMS Score Observation ^c

An annotation describing a piece of music annotated on the basis of a music score.

A observation defined on a symbolic notation or on a music score, i.e. described from a temporal point of view using references to symbolic elements defined by the notation itself.

• Is Observation Of ^op only
  
• Is Observation Of ^op exactly 1
  

The duration of a MusicTimeInterval, which defines a value and a ValueType.

• Has Music Time Value Type ^op only
  
• Is Music Time Duration Of ^op only
  
• Has Music Time Value Type ^op exactly 1
  
• Has Value ^dp some
  
• Has Value ^dp exactly 1
  

An index that defines a point in a musical sequence, whether it is a temporal sequence (expressed in real time) or a symbolic sequence (expressed in symbolic time).

• Has Music Time Index Component ^op
• Is Music Time Index Of ^op

• Has End Music Time Index ^op

• Has Music Time Index Component ^op only
  
• Is Music Time Index Of ^op only
  
• Has Music Time Index Component ^op min 1
  

A component of a MusicTimeIndex, which defines the value of the component and its ValueType. Multiple MusicTimeIndexComponents are required for representing points on a sequence that requires more than one value to be defined. For example, a symbolic notation usually needs beats and measures to define a point on a sequence: in this case there will be a MusicTimeIndexComponents defining the measure position and another MusicTimeIndexComponents for defining the beat position.

• Has Music Time Value Type ^op only
  
• Is Music Time Index Component Of ^op only
  
• Has Music Time Value Type ^op exactly 1
  
• Has Value ^dp some
  
• Has Value ^dp exactly 1
  

The interval in which an Annotation or an Observation takes place. It describe the time frame in which the Annotation/Observation is valid.

• Has End Music Time Index ^op
• Has Music Time Duration ^op

• Has Music Time Duration ^op only
  
• Has Music Time Index ^op only
  
• Has Music Time Index ^op min 1
  
• Has Music Time Duration ^op exactly 1
  

It defines the type of the temporal value being represented, for example seconds for audio annotations and beat/measure for score annotations.
