In classification, one of the distinguishing characteristics of a class, identified as a means of differentiating it from other classes. As defined in FRBR (Functional Requirements for Bibliographic Records), one of a set of characteristics enabling users of information to formulate queries and evaluate responses when searching for information about a specific entity. Attributes can be inherent in the entity (physical characteristics, labeling information, etc.) or supplied by an external agent (assigned identifiers, contextual information, etc.). For example, the logical attributes of a creative work include its title, form, date of creation, intended audience, etc. As a general rule, a given instance of an entity exhibits a single value for each attribute, but multiple values are possible (a work may be published under more than one title or in more than one form), or a value may change over time (date of publication for serials).
