Ian Callanan Kay Robbins Scott Makeig This ontology defines the HED Hierarchical Event Descriptor schema structure. This ontology only defines the structural elements of the HED schema. The actual HED tags are in HED. HED Schema Ontology (HEDS) HED Schema Ontology releases/2024-06-10 The unique identifier of this element in the HED namespace. Maps HedElement into string. hedId This tag requires that a descendent node be included. Maps a HedTag into a boolean. requireChild This top-level library schema node should have a parent which is the indicated node in the partnered standard schema. Maps a HedTag into a HedTag name as a string. rooted This tag is a hashtag placeholder that is expected to be replaced with a user-defined value. Maps a HedTag into a boolean. takesValue The unique identifier of this element in the HED namespace. true true hedId This tag must have a descendent. true true requireChild This top-level library schema node should have a parent which is the indicated node in the partnered standard schema. true true rooted This tag is a hashtag placeholder that is expected to be replaced with a user-defined value. true true takesValue The value is not inherited by child nodes. annotationProperty This schema attribute's value can be true or false. This property was formerly named boolProperty. boolRange This schema attribute can apply to any type of element class (i.e., tag, unit, unit class, unit modifier, or value class). This property was formerly named elementProperty. elementDomain This schema attribute can apply to node (tag-term) elements. This was added so attributes could apply to multiple types of elements. This property was formerly named nodeProperty. tagDomain This schema attribute's value can be a node. This property was formerly named nodeProperty. tagRange This schema attribute's value can be numeric. numericRange This schema attribute's value can be a string. stringRange This schema attribute can apply to unit classes. This property was formerly named unitClassProperty. unitClassDomain This schema attribute's value can be a unit class. unitClassRange This schema attribute can apply to unit modifiers. This property was formerly named unitModifierProperty. unitModifierDomain This schema attribute can apply to units. This property was formerly named unitProperty. unitDomain This schema attribute's value can be units. unitRange This schema attribute can apply to value classes. This property was formerly named valueClassProperty. valueClassDomain This schema attribute's value can be a value class. valueClassRange Associates a HedSchema with some HedEntity. This is a structural property which allows tools to place an element in its correct schema. hasHedEntity Associates a HedEntity with its particular HedSchema class. This is a structural property which allows tools to place an element in its correct schema. inHedSchema Associates a HedUnit with its category (HedUnitClass). This is a structural property which allows tools to place a unit in its correct grouping. hasUnitClass The default units to use if the placeholder has a unit class but the substituted value has no units. defaultUnits A HED tag that is closely related to this tag. This attribute is used by tagging tools. relatedTag A tag is often associated with this tag. This attribute is used by tagging tools to provide tagging suggestions suggestedTag The unit class this placeholder tag belongs to. Maps a HedTag into a HedUnitClass name as a string. unitClass The value class this placeholder tag belongs to. Maps a HedTag into a HedValueClass name as a string. valueClass The default units to use if the placeholder has a unit class but the substituted value has no units. true true defaultUnits A HED tag that is closely related to this tag. This attribute is used by tagging tools. true true relatedTag A tag that is often associated with this tag. This attribute is used by tagging tools to provide tagging suggestions. true true suggestedTag The unit class that the value of a placeholder node can belong to. true true unitClass Type of value taken on by the value of a placeholder node. true true valueClass This tag is part of the indicated tag -- as in the nose is part of the face. true true isPartOf The semantic version of this schema. version The name of the library schema if applicable, otherwise an empty string. library If true, the schema is not merged with a partner schema. unmerged The version of the HED schema's standard schema partner. withStandard A schema attribute of value classes specifying a special character that is allowed in expressing the value of a placeholder. Normally the allowed characters are listed individually. However, the word letters designates the upper and lower case alphabetic characters and the word digits designates the digits 0-9. The word blank designates the blank character. allowedCharacter The factor to multiply these units or unit modifiers by to convert to default units. conversionFactor Indicates that this element is deprecated. The value of the attribute is the latest schema version in which the element appeared in undeprecated form. deprecatedFrom A schema attribute indicating that users can add unlimited levels of child nodes under this tag. This tag is propagated to child nodes with the exception of the hashtag placeholders. extensionAllowed This element comes from the indicated library version. This attribute is added by tools when a library schema is merged into its partnered standard schema. inLibrary This tag has special meaning and requires special handling by tools reserved Indicates that this unit element is an SI unit and can be modified by multiple and submultiple names. Note that some units such as byte are designated as SI units although they are not part of the standard. SIUnit This SI unit modifier represents a multiple or submultiple of a base unit rather than a unit symbol. SIUnitModifier This SI unit modifier represents a multiple or submultiple of a unit symbol rather than a base symbol. SIUnitSymbolModifier This tag can only appear inside a tag group. tagGroup This tag (or its descendants) can only appear in a top-level tag group. A tag group can have at most one tag with this attribute. topLevelTagGroup Only one of this tag or its descendants can be used in the event-level HED string. unique This unit is a prefix unit (e.g., dollar sign in the currency units). unitPrefix This is an abbreviation or symbol representing a type of unit. Unit symbols represent both the singular and the plural and thus cannot be pluralized. unitSymbol A special character that is allowed in expressing the value of a placeholder of a specified value class. Allowed characters may be listed individual, named individually, or named as a group as specified in Section 2.2 Character sets and restrictions of the HED specification. true true true true allowedCharacter The factor to multiply these units or unit modifiers by to convert to default units. true true true conversionFactor The latest schema version in which the element was not deprecated. true true deprecatedFrom Users can add unlimited levels of child nodes under this tag.

Chewing-artifact hed:HED_0012496 An electrical artifact from the far-field potential from pulsation of the heart, time locked to QRS complex. ECG-artifact hed:HED_0012497 Artifact from muscle activity and myogenic potentials at the measurements site. In EEG, myogenic potentials are the most common artifacts. Frontalis and temporalis muscles (e.g. clenching of jaw muscles) are common causes. Generally, the potentials generated in the muscles are of shorter duration than those generated in the brain. The frequency components are usually beyond 30-50 Hz, and the bursts are arrhythmic. EMG-artifact hed:HED_0012498 Ocular movements and blinks can result in artifacts in different types of data. In electrophysiology data, these can result transients and offsets the signal. Eye-artifact hed:HED_0012499 Artifact from eye blinking. In EEG, Fp1/Fp2 electrodes become electro-positive with eye closure because the cornea is positively charged causing a negative deflection in Fp1/Fp2. If the eye blink is unilateral, consider prosthetic eye. Eye-blink-artifact hed:HED_0012500 Eye movements can cause artifacts on recordings. The charge of the eye can especially cause artifacts in electrophysiology data. Eye-movement-artifact hed:HED_0012501 Artifact from moving eyes left-to-right and right-to-left. In EEG, there is an upward deflection in the Fp2-F8 derivation, when the eyes move to the right side. In this case F8 becomes more positive and therefore. When the eyes move to the left, F7 becomes more positive and there is an upward deflection in the Fp1-F7 derivation. Horizontal-eye-movement-artifact hed:HED_0012502 Artifact from nystagmus (a vision condition in which the eyes make repetitive, uncontrolled movements). Nystagmus-artifact hed:HED_0012503 Artifacts originating from slow, rolling eye-movements, seen during drowsiness. Slow-eye-movement-artifact hed:HED_0012504 Artifact from moving eyes up and down. In EEG, this causes positive potentials (50-100 micro V) with bi-frontal distribution, maximum at Fp1 and Fp2, when the eyeball rotates upward. The downward rotation of the eyeball is associated with the negative deflection. The time course of the deflections is similar to the time course of the eyeball movement. Vertical-eye-movement-artifact hed:HED_0012505 Artifact in the measured data generated by motion of the subject. Movement-artifact hed:HED_0012506 A mechanical artifact from a pulsating blood vessel near a measurement site, cardio-ballistic artifact. Pulse-artifact hed:HED_0012507 Artifact from breathing.

In EEG, this is a low amplitude undulating waveform that is usually greater than 2 seconds and may appear to be an unstable baseline. Sweat-artifact hed:HED_0012511 Artifact from tongue movement (Glossokinetic). The tongue functions as a dipole, with the tip negative with respect to the base. In EEG, the artifact produced by the tongue has a broad potential field that drops from frontal to occipital areas, although it is less steep than that produced by eye movement artifacts. The amplitude of the potentials is greater inferiorly than in parasagittal regions; the frequency is variable but usually in the delta range. Chewing and sucking can produce similar artifacts. Tongue-movement-artifact hed:HED_0012512 A data artifact arising from a non-biological source. Nonbiological-artifact hed:HED_0012513 Artifact stemming from mechanical ventilation. These can occur at the same rate as the ventilator, but also have other patterns.
