write_prov_tsv: write provenance as tsv file

In cboettig/prov: A Semantic Data Provenance Index

write provenance as tsv file

Description

Write provenance metadata to a table. While this format is less expressive than JSON-LD, it is also more efficient, particularly when data is appended. At this time, only documents dcat:Distribution (schema:DataDownload) types. Column names are taken from DCAT but no official namespace is set.

Usage

write_prov_tsv(
  data_in = NULL,
  code = NULL,
  data_out = NULL,
  meta = NULL,
  issued = as.character(Sys.Date()),
  theme = NA_character_,
  keyword = NA_character_,
  provdb = "prov.tsv",
  append = fs::file_exists(provdb)
)

Arguments

data_in	path or URI for input data
code	path or URI for code
data_out	path or URI to output data
meta	path or URI to metadata describing the workflow
issued	publication date, as Date or character object
theme	theme name
keyword	keyword
provdb	path to output JSON file, default "prov.json"
append	Should we append to existing json or overwrite it?
