This instance represents the containing Context itself. 1 1 1 1 1 0 1 0 1 1 URI that uniquely identifies a Context (earlier refered to as a ContextRef or ContextURI) Instances of this class are used as the domain of a set of higgins:metadata properties that, taken together, are considered to be the metadata about a higgins:attribute sub-property. Used as the super-Property of some DatatypeProperties whose domain is higgins:ValeAndMetadata or higgins:DigitalSubject to indicate that these properties are considered to be metadata about the ValueAndMetadata (or DigitalSubject) Instances of this property are used to point to one or more values (i.e. cases where the range is higgins:Value). One instance (at most) may also be used to point to a holder of metadata (an instance of higgins:Attribute) about the entire set of values. Used as the super-Property of some ObjectProperties of higgins:ValueAndMetadata or higgins:DigitalSubject to indicate that these properties are considered to be metadata about the ValueAndMetadata (or DigitalSubject) A directed relation between two Digital Subjects A directed relation between two Digital Subjects believed to represent the same underlying Entity
