ROCrateMetadataFileElem Model¶

The ROCrateMetadataFileElem model is a special entity required by the RO-Crate specification. It describes the ro-crate-metadata.json file itself. Its primary purpose is to declare conformance to a specific version of the RO-Crate specification and to identify which entity in the @graph is the "Root Dataset" via the about property.

Properties¶

Property	Type	Description	Required
`guid` (alias: `@id`)	`str`	The identifier for this entity. It must be `"ro-crate-metadata.json"`.	Yes
`metadataType` (alias: `@type`)	`Literal["CreativeWork"]`	The schema.org type. It must be `"CreativeWork"`.	Yes
`conformsTo`	`IdentifierValue`	A link to the specific version of the RO-Crate specification the crate adheres to.	Yes
`about`	`IdentifierValue`	A link to the "Root Dataset" entity (`ROCrateMetadataElem`) within the `@graph`.	Yes

Example¶

This entity is typically the first item in the @graph list of an ro-crate-metadata.json file.
