dataset facet
In the RDF universe, a dataset is a collection of one or more RDF graphs.
In a semantic mesh, there are two kinds of datasets:
- node flows are dcat:DatasetSeries (which are also dcat:Dataset) and represent an "abstract dataset": they don't have concrete distributions of their own.
- Flow data is only materialized in FlowShot distributions.
- Metadata about the various flows is consolidated in the node's metadata flow in the form of distributions.
- paylod nodes contain a "payload flow" and their intramesh identifiers refer to that payload dataset in the abstract. The dataset is still contained in a particular kind of node flow, i.e., a mesh-resource.node-component.flow.dataset (Private). But the flow's identifier refers to a particular flow, whereas the node identifier will become the canonical IRI of the dataset (on publication).
- in the case of mesh-resource.node-component.flow.dataset (Private), they can store their Dataset metadata in the dataset itself, or in their reference flow, or both.
- FlowShots are dcat:Dataset and represent a specific version of their abstract datasets; they have one or more snapshot distributions.
