Decorations

Decorations are domain-specific extensions of ProcessCore. They specialize core types through additionalType, define decoration-specific properties, and add entities only where the domain needs concepts that do not have a direct ProcessCore counterpart.

Available Decorations

Decoration	Domain
ISA	Investigation, Study, Assay, Source, Sample, and ISA property-value roles
Workflow Run	Workflow and Run datasets, workflow protocols, and workflow invocations
Datamap	Datamap datasets and DataContext annotations for file fragments

Extension Rules

• Do not modify ProcessCore entities for a decoration.
• Use additionalType to discriminate specializations.
• Prefer additionalProperty for extensible metadata that can compose across decorations.
• Add decoration-specific entities only when the concept does not fit a core type.
