Profiles

The ARC Data Model specification defines three peer profiles that together form the general ARC RDM model. The implementation uses one unified object model; the profiles describe coherent subsets of the same model surface.

Reading Order

1. ARC Core
2. Datamap
3. Administrative
4. ARC Workspace Project File
5. Querying

Principles

• Process-centric: experiments and workflows are modeled as processes connecting inputs to outputs.
• Unified: ARC Core, Datamap, and Administrative properties are available on the shared model types rather than split into separate runtime objects.
• Extensible: Annotation and additionalType carry domain-specific information while typed properties cover the common profile surface.
• Representation-aware but model-first: SQL and YAML schemas derive from the markdown spec.

Main Areas

Area	Description
ARC Core	Provenance model: Dataset, Process, Recipe, Sample, Data, Annotation, FormalParameter, and DefinedTerm
Datamap	Data files, selected fragments, fragment descriptors, and dataset-level data contexts
Administrative	Dataset agents, affiliations, citations, licenses, dates, and administrative metadata
Decorations	ISA and Workflow Run mappings layered onto the unified model
ARC Workspace Project File	Bidirectional rules for partitioning ARC metadata across local resources
Querying	Query use cases and graph traversal notes
