ROCrateMetadataElem Model¶

The ROCrateMetadataElem model represents the "Root Dataset" entity within an RO-Crate. This is the main descriptive node for the crate as a whole, containing high-level metadata such as its name, author, and license. It also uses the hasPart property to link to all other data and metadata entities packaged within the crate.

Property	Type	Description	Required
`guid` (alias: `@id`)	`str`	The unique, resolvable identifier for the RO-Crate itself.	Yes
`metadataType` (alias: `@type`)	`List[str]`	A list of types for the root entity. Typically `["Dataset", "https://w3id.org/EVI#ROCrate"]`.	Yes
