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.
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
