Component: Attribute

  • Attribute describes a dataset or concept attribute with optional textual information, data type, and values.

  • It can optionally reference a concept corresponding to the attribute values.

  • The attribute's data type can be specified using a "ref" attribute and optionally formatted using a "format" attribute.

  • An optional "id" can be provided, which must be unique within the concept, otherwise it's implicitly derived from the referenced concept.

Attributes
QName Type Fixed Default Use Annotation
concept xs:QName optional A reference to a concept that corresponds to the values of the attribute. If the attribute specifies a type, then the type must match the type of the referenced concept. A reference to an external concept must be of the form "prefix:other_concept_id", where "prefix" is the prefix used for the namespace of the external dataset (see XML namespaces).
id LocalId optional The id of the concept attribute. This identifier must be unique within the concept (across attributes and properties). The id may be omitted if the concept attribute is specified. In that case, an id is implicity created with value the local name of the referenced concept. For instance <attribute concept="unit:currency"/> is equivalent to <attribute id="currency" concept="unit:currency"/>
