Writes provenance and Dublin Core metadata of a dataset to a file or connection in N-Triples format.

Usage

describe(x, con)

Arguments

x

A dataset_df object.

con

A connection or a character string path (e.g. from tempfile()).

Value

Writes N-Triples to con and invisibly returns x.

Examples

test_ds <- dataset_df(
  rowid = defined(c("eg:1", "eg:2"),
    namespace = "http://example.com/dataset#"
  ),
  geo = defined(
    gdp$geo[1:2],
    label = "Country",
    concept = "http://example.com/prop/geo",
    namespace = "https://eionet.europa.eu/geo/$1"
  ),
  dataset_bibentry = dublincore(
    title = "Example Dataset",
    creator = person("John", "Doe")
  )
)

# returns invisibly the contents of the text file serialisation:
testdescription <- describe(test_ds, con = tempfile())
testdescription
#> Doe (2025): Example Dataset [dataset]
#>   rowid     geo       
#>   <defined> <defined>
