dcatbyteSize

dcatbyteSize is a shorthand sometimes used to refer to the DCAT vocabulary term dcat:byteSize, a property defined in the Data Catalog Vocabulary (DCAT). The canonical property name is dcat:byteSize, and many DCAT descriptions use this exact label. In some documentation or discussions, the term may appear as dcatbyteSize, but it denotes the same concept: the size of a distribution measured in bytes.

Definition and data type. dcat:byteSize attaches to a dcat:Distribution and conveys the size of the distribution’s downloadable representation in bytes. The value is an xsd:nonNegativeInteger, representing the number of bytes. The size is intended to reflect the actual file size at the time the distribution is retrieved, though it may be unknown or approximate in some catalogs.

Usage and interpretation. Publishers include dcat:byteSize to aid data consumers in planning downloads and storage, and to enable quick comparisons among distributions. Because the size can change for dynamic or regularly updated resources, the property may be omitted or updated when the resource changes. For multi-part or multipart distributions, each part may have its own byteSize.

Relation to other metadata. dcat:byteSize is commonly used alongside dcat:downloadURL to indicate what is being downloaded and its location. It is independent of content encoding or compression; the value typically reflects the size of the resource as retrieved from the URL, often the compressed file in the distribution.
