The BioSignalML Ontology

A collection of Signals held as a named entity, all pertaining to one thing (the subject) and which have been recorded in the same session.

A sequence of periodic measurements of some physical quantity, ordered by some sampling dimension, normally time. A Signal is part of some Recording.

Something that has occurred in time, possibly for some duration.

A general note, comment, or qualitative measure about the whole of, or some portion of, a Recording, Signal or Event.

A signal that has been sampled at a constant rate.

• bsml:LP_Filter ^c
• bsml:Notch_Filter ^c

A band-pass filter.

A high-pass filter.

A low-pass filter.

A notch (blocking) filter.

The source (i.e. device, simulation, etc) of a Signal or Recording.

• bsml:Simulation ^c
• bsml:Device ^c

A computer simulation or modelling process that created the Signal or Recording.

A physical device that converts the output of a sensor into a format able to be stored.

What actually captured a signal -- an electrode, transducer, etc.

• bsml:Transducer ^c
• bsml:Electrode ^c

A device that converts a measurable quantity into an electrical signal (e.g. thermistor, pressure sensor, strain gauge).

An electrical conductor in contact with non-conducting material, through which electrical activity can be measured.

The class or type of signal (e.g. EEG, ECG).

Something which is the class or type of an Event.

Some measurement of time, either a particular point in time or some interval.

• bsml:Instant ^c
• bsml:Interval ^c

A particular point in time.

A period in time.

• The class used to represent the types of measurement units used by signals.

• Measurement units would normally be entities in a specialised units of measure ontology.

A RDF graph containing Recording metadata, used for managing provenance.

A tag used to classify a resource.

A tag to indicate that an annotation relates to some form of error.

Pre-filtering applied to a signal as part of collection.

The Recording a Signal is part of.

What was used to collect or derive an electrical signal.

The location of actual data, in a format suitable for computer processing.

A signal's generic type.

The class or type of an Event.

• The physical units that are represented by a signal's data values.

• Specification of units allows for consistency checking and automatic conversion.

The sampling coordinates associated with a signal's data values.

• A semantic tag given to a resource by an annotation.

• Tags are effectively controlled keywords.

An instant or interval associated with a resource.

A resource describing the measurement uncertainty associated with a Recording, Signal, or Segment.

The binary-bit resolution of the analogue-to-digital convertor or sampling device used to digitise the signal.

The minimum frequency, in Hertz, contained in the signal.

The maximum frequency, in Hertz, contained in the signal.

The cutoff frequency, in Hertz, of a filter.

The maximum value of the signal.

The minimum value of the signal.

The sampling period, in seconds, of a uniformly sampled signal.
