WF Manifest Schema

WF Manifest is a JSON Schema for representing the output of the PID-LAND special-pid like wf-search and wf-select in RO-Crate / manifest format. It is used to organize waveform metadata into a structured dataset with proper provenance and references.

---

Purpose

• Standardize RO-Crate / manifest representation of waveform datasets.
• Enable automatic validation via JSON Schema.
• Support FAIR principles: Findable, Accessible, Interoperable, Reusable.
• Integration with other workflow components: wf-handle and wf-provenance.

---

Format and Structure

• Main type: object
• Required fields: @context, @graph
• Type checks: string, array, object
• Graph items: can be a Dataset, CreativeWork, or MediaObject
• Strict field consistency: additionalProperties: false ensures no unexpected fields.

---

Key Properties

Field	Type	Description
@context	string (URI)	Reference to JSON-LD context, e.g., RO-Crate context
@graph	array	List of entities in the manifest
@id	string	Unique identifier (URI) for the entity
@type	string	Entity type (Dataset, CreativeWork, MediaObject)
name	string	Human-readable name of the entity
hasPart	array	References to constituent parts of a dataset (for Dataset)
about	object	Indicates what the CreativeWork describes
encodingFormat	string	MIME type of the media object (for MediaObject)

Validation

• JSON Schema: ensures manifest structure is correct.
• SHACL: RDF-level validation of relationships.
• Checks include:
  • Dataset must have at least one hasPart
  • CreativeWork must have an about property

Notes

The schema is designed to link with WF Handle and WF Provenance outputs.

Together they implement a PID-centric, information-centric metadata model supporting FAIR data management, reproducible science, and long-term preservation.
