Example Dataset Definitions"
In dataset: Create Data Frames for Exchange and Reuse

This page documents the illustrative IRIs used in the dataset package vignettes. They are examples only and do not point to real datasets.

Purpose

To illustrate how IRIs can uniquely identify dataset elements.
To provide dereferenceable links that pass CRAN checks.
To show Linked Data best practice: one namespace doc, with fragments.

Example Dataset Definitions For RDF

The base namespace in vignette("rdf", package = "dataset") is:

https://dataset.dataobservatory.eu/examples/dataset.html#

Although these example IRIs use .html# in the base namespace, the .html part does not imply that the resource is literally an HTML file. In RDF, any absolute IRI is valid. We use this form only for illustration, because the R package documentation infrastructure is not designed to support full content negotiation between human-readable HTML and machine-readable Turtle files.
In real publishing scenarios, a bare namespace ending with /dataset# is more conventional.

obs:1

Example observation 1 (not real data).

obs:2

Example observation 2 (not real data).

obs:3

Example observation 3 (not real data).

In real publishing scenarios, you would replace these with persistent URIs that identify actual datasets and their observations. For example, a DOI-based identifier such as:

https://doi.org/10.5281/zenodo.14917851#obs:1

could be used to refer to the first observation in a dataset archived at Zenodo.

Machine-readable form

A Turtle serialization of the same example definitions is also available:

@prefix ex:   <https://dataset.dataobservatory.eu/examples/dataset#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix dcat: <http://www.w3.org/ns/dcat#> .

ex:obs1 a dcat:Observation ;
    rdfs:label "Example observation 1 (not real data)" .

ex:obs2 a dcat:Observation ;
    rdfs:label "Example observation 2 (not real data)" .

ex:obs3 a dcat:Observation ;
    rdfs:label "Example observation 3 (not real data)" .

In fact, semantic applications know that they should not even read this HTML page, but instead go directly to the dataset.ttl version, as it is a World Wide Web standard to disseminate data and metadata.
