Classes

The classes are presented in the following format. Class names that start with the letter “PH” followed by a number are presented in bold typeface, followed by the description. The “SubclassOf” field indicates the parent class from which the current class inherits properties and characteristics. The “SuperClassOf” field lists any classes that are direct descendants of the current class, inheriting its properties and characteristics. The “Properties” field lists the properties that instances of the class may have, with descriptions of their domains, ranges, and any hierarchical relationships. 

PH1 Performance

This class describes a performance as a culturally significant event constrained by time, conducted by one or more agents at a specific location. A performance represents a unique presentation in a defined setting, whether it is staged, ritualistic, musical, theatrical, or improvised, often leaving traces like written records, images, accounts, or oral histories. It can happen alone or as part of larger events such as productions, festivals, or tours, taking various forms including ritual, theatre, puppetry, dance, storytelling, or musical acts. Performances may take place in formal, communal, migratory, or diasporic contexts such as kampungs, schools, temples, and amusement parks. Here, performances are actual events rather than abstract works or repertoires.

PH3 Performance Genre

This classifies the main genre of a performance. Genres represent artistic forms and cultural practices, such as opera, puppet theatre, music, dance, comedy, drama, or rituals. These genres are seen as inherited, hybridised, and adapted locally, reflecting regional and diasporic histories. The class aids in comparative analysis and classification using a controlled vocabulary, while distinguishing between broad canonical traditions and more localised or vernacular forms.

Properties:

PH4 Theme

This class identifies the central theme or motif explored or expressed in a performance. Themes may be personal (such as love or grief), political (such as resistance or migration), or spiritual (such as rebirth or cosmology). They often recur across genres, repertoires, and historical periods, serving as conceptual threads within performance histories.

Properties:

PH5 Performance Style

This class defines the artistic and expressive modality by which a performance is delivered—its “how”. Style includes bodily movement, vocal quality, gesture systems, visual aesthetics, and design traditions. These are often shaped by regional schools, cultural conventions, diasporic formations or personal innovation. A performance may present multiple styles or a fusion of styles, and styles often evolve through adaptation and circulation.

Properties:

PH6 Performance Element

This class groups the constituent elements that make up or structure a performance. These may include textual materials, performing objects, staging configurations, sonic elements, movement and gesture, and systems of performance knowledge or transmission. It functions as a unifying superclass for modelling the internal components of performance, whether material, enacted, or conceptual.

SubclassOf: PH1 Performance

Properties:

PH7 Performance Text

This class models the written, recited, chanted, or otherwise language-based textual elements used in a performance, such as scripts, libretti, cue sheets, oral recitations, and chants. These texts may function as formal templates, improvisational frameworks, mnemonic aids, or carriers of narrative, ritual, and poetic meaning. In many Southeast Asian performance traditions, textual transmission may be oral, partially notated, or informally annotated, making this class important for documenting both written and intangible textual practices.

Superclass Of: None

Subclass Of: PH6 Performance Element E33 Linguistic Object

PH23 Character

This class models the fictional, mythological, symbolic, or historically stylised personas portrayed in performances. Characters may be unique to a specific performance or part of an established narrative, theatrical, ritual, or oral tradition. They may embody archetypes such as heroes, gods, demons, tricksters, warriors, ancestors, or comic figures. In many Southeast Asian performance traditions, characters are not merely narrative functions but also express cosmological roles, social hierarchies, ethical paradigms, or ritual significance, often conveyed through gesture, costume, voice, music, and movement. This class supports the modelling of character identities as conceptual constructs that can be linked to performances, performer roles, and performance conventions. Superclass Of: None Subclass Of: E28 Conceptual Object Properties:

PH24 Work
