See [background notes](/docs/datamodel.html#identifierBg) for more details.

Scope

Domain: Thing (https://schema.org/Thing). Range: PropertyValue (https://schema.org/PropertyValue), Text (https://schema.org/Text), URL (https://schema.org/URL).

CDIF

Definition

The primary identifier for the dataset; other identifiers should be listed in the sameAs field. Schema.org has three ways of encoding identifiers-- a text description, a URL, or by using the schema:PropertyValue field. The Science on Schema.org guidance strongly recommends using the PropertyValue approach. see https://github.com/ESIPFed/science-on-schema.org .... Dataset.md#identifier. Ideally, for any given data provided they would provide identifiers either all as strings or all as identifier_type.

Scope

@id - resolvable URI when the concept-or-term branch is used; absent when the value is a plain string.
