Create a Salmon Data Package

Assembles a Frictionless Data Package with salmon-specific semantic fields (IRIs, concept schemes, etc.) and writes resources plus datapackage.json to disk.

Usage

create_salmon_datapackage(
  resources,
  dataset_meta,
  table_meta,
  dict,
  codes = NULL,
  path,
  format = "csv",
  overwrite = FALSE
)

Arguments

resources

Named list of data frames/tibbles (one per resource)

dataset_meta

Tibble with dataset-level metadata (one row)

table_meta

Tibble with table-level metadata (one row per table)

dict

Dictionary tibble with column definitions

codes

Optional tibble with code lists

path

Character; directory path where package will be written

format

Character; resource format: "csv" (default, only format supported)

overwrite

Logical; if FALSE (default), errors if path exists

Value

Invisibly returns the path to the created package

Examples

if (FALSE) { # \dontrun{
# Create a simple package
resources <- list(main_table = mtcars)
dataset_meta <- tibble::tibble(
  dataset_id = "test-1",
  title = "Test Dataset",
  description = "A test dataset"
)
table_meta <- tibble::tibble(
  dataset_id = "test-1",
  table_id = "main_table",
  file_name = "main_table.csv",
  table_label = "Main Table"
)
dict <- infer_dictionary(mtcars, dataset_id = "test-1", table_id = "main_table")
create_salmon_datapackage(
  resources, dataset_meta, table_meta, dict,
  path = tempdir()
)
} # }
