SCOVO – Statistical Core Vocabulary


A vocabulary for representing statistical data. Three basic concepts are used: a dataset, representing the container of some data, such as a table holding some data in its cells; a data item, representing a single piece of data (e.g. a cell in a table); a dimension, representing some kind of unit of a single piece of data (for example a time period, location, etc.)
