Class: Thing

Root of the type hierarchy. Carries the identity and naming slots shared by every node that appears in a record's JSON-LD — the top-level resource and every nested object (Person, Organization, Place, Language, DefinedTerm, License, etc.). Modeled as its own class, not folded into CreativeWork, because those nested classes are Things but not CreativeWorks.

Slots

Name	Cardinality and Range	Description	Inheritance
id	1 Uriorcurie	Unique identifier (IRI/URL) for this resource. In JSON-LD, @id represents the globally unique identifier. (Maps to @id; the identifier slot is bound to @id by gen-jsonld-context.)	direct
identifier	0..1 recommended String	Primary persistent identifier for this resource (e.g., DOI, Handle, ARK, or persistent URL). Can be a simple string or PropertyValue object.	direct
name	0..1 String	Title or name of the digital object, page, or resource.	direct
description	0..1 String	Brief description of the data. For datasets: what is included (variables, measurements), method/origin. For software: what it does, access requirements, supported languages.	direct
url	0..1 Uri	URL to the website that contains and/or describes the digital object or person.	direct
sameAs	0..1 Uri	URL of a reference web page that unambiguously indicates the item's identity (e.g., ORCID profile, Wikidata entry). NOTE: deliberately NOT mapped to dcat:landingPage — although CreativeWork populates sameAs from the landing page, this is a generic Thing slot (a Person's sameAs is an ORCID, not a landing page), so the landing-page equivalence is builder behavior, not a slot-level fact.	direct
