Distribution

A physical embodiment An available distribution of the Dataset in a particular media formatdataset.

Used to describe the different ways that a single dataset can be made available in. I.e., it can be downloaded or it can be accessed online in one or more distributions (e.g. one in a downloadable .csv file, another file with an access or query webpage)

dcat:Distribution

Dataset Series

A resource type.

Dataset series are defined in [ISO-19115] as a collection of datasets […] sharing common characteristics. However, their use is not limited to geospatial data, although in other domains they can be named differently (e.g., time series, data slices) and defined more or less strictly (see, e.g., the notion of "dataset slice" in [VOCAB-DATA-CUBE]).

With "dataset series" we refer to data, somehow interrelated, that are published separately. An example is budget data split by year and/or country, instead of being made available in a single dataset.

dcat:Dataseries

Data Service

A Resource type.
