How to model dataset series?
- Approaches for time series, dataset slices, other relationships
During the revision process of DCAT-AP in 2015, it was noted that the DCAT specification only considers relationships between a catalogue and the datasets described in the catalogue, and between a dataset and the distributions that represent the manifestations of the dataset.
The specification of DCAT is silent on any relationships between catalogues, between datasets and between distributions.
In real-world implementations, such relationships do exist and may be modelled in different ways. An example of such relationships are time-series. In some implementations, time-series are modelled as distributions of a single dataset; in others, as separate datasets with or without links between them.
A common approach to modelling such relationships in DCAT-AP would improve interoperability among catalogues.
