Class: AttributeSpecification

An attribute is conceptually a thing, but it requires no dedicated identifier (id). Instead, it is linked to a Thing via its has_attributes slot and declares a predicate on the nature of the relationship.

Examples

Example: AttributeSpecification-01-minimal

# Technically, the only required aspect of an AttributeSpecification
# is a predicate. That is because an attribute may not only have a
# single value, but is a more complex collection of attribute facets.
predicate: dcterms:title
value: "My attribute"

Example: AttributeSpecification-02-with-attributes

# An attribute without a singular value, but attributes of it
# own instead.

    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.
