Bonjour Hélène,
Pour les notions d' "incarnation" d'un film dans un support (physique ou virtuel), le standard PB Core dispose de la notion d' "instantiation". Voir ici : https://pbcore.org/elements/pbcoreinstantiation
pbcoreInstantiation contains subelements that describe a single instantiation of an asset. The definition is malleable, but it should be thought of as any discreet and tangible unit that typically (though not always) comprises a whole representation of the asset. For example, an original master videotape, a preservation master video file, and a low-bitrate access copy would all be considered Instantiations of a single video program. All of the sub-elements held by this element are used to describe the instantiation specifically, not necessarily the asset as a whole.
C'est exactement ce que vous cherchiez : "an original master videotape, a preservation master video file, and a low-bitrate access copy"
En relisant en diagonale le profil PBCore, cela devrait être une relation avec une nouvelle fiche objet du type "Supporting materials", depuis l'écran prévu à cet effet "Instantiations".
