Class: Thing
The most basic, identifiable item. In addition to the slots that are common between a Thing
and an AttributeSpecification
(see ThingMixin
), two additional slots are provided. The id
slot takes the required identifier for a Thing
. The relation
slot allows for the inline specification of other Thing
instances. Such a relation is unqualified (and symmetric), and should be further characterized via a Statement
(see is_characterized_by
). From a schema perspective, the relation
slots allows for building self-contained, structured documents (e.g., a JSON object) with arbitrarily complex information on a Thing
.

description: Declares a relation that associates a `Thing` (or another attribute)
with an attribute, where an attribute is an intrinsic characteristic, such as
a quality, capability, disposition, function, or is an externally derived attribute
determined from some descriptor (e.g. a quantity, position, label/identifier).
Technically, this declaration is done via an `AttributeSpecification` that combines
a `predicate` with a value declaration and the attribute-related slots of a
`Thing`. Importantly, such attributes are declared inline, because they do not
have a unique identifier. If an identifier is available, a `Thing` declaration
(see `relation`), and a qualification of that relationship via a `Statement`
(see `is_characterized_by`) should be preferred.
