DCAT2 representation

This page details how to represent the information definition outlined in Complex and simple types using DCAT2. It mostly concerns dataset and dataset series. For example, the queryDatasets operation may return DCAT structured data.

DCAT 2 is used in https://www.europeandataportal.eu/en

Assumptions

DatasetSeries is close to being a DCAT catalog
Dataset is the overarching concept - maps to DCAT Dataset
The actual file maps to DCAT Distribution
