The goal of this vignette is to provide an explicit map between the metadata fields used by cffr and each one of the valid keys of the Citation File Format schema version 1.2.0.
Summary
We summarize here the fields that cffr can parse and the original source of information for each one of them. The details on each key are presented on the next section of the document. The assessment of fields are based on the Guide to Citation File Format schema version 1.2.0 (Druskat et al. 2021).

abstract
This key is extracted from the “Description” field of the DESCRIPTION file.
Example
library(cffr)
# Create cffr for yaml
cff_obj <- cff_create("rmarkdown")
# Get DESCRIPTION of rmarkdown to check
pkg <- desc::desc(file.path(find.package("rmarkdown"), "DESCRIPTION"))
cat(cff_obj$abstract)
#> Convert R Markdown documents into a variety of formats.
cat(pkg$get("Description"))
#> Convert R Markdown documents into a variety of formats.authors
This key is parsed from the “Authors” or “[email protected]” field of the DESCRIPTION file. Only persons with the role “aut” or “cre” are considered.
Example
cff_obj <- cff_create("rmarkdown")
pkg <- desc::desc(file.path(find.package("rmarkdown"), "DESCRIPTION"))

This key can be set via the parameters of the cff_create()/cff_write() functions:
Example
cff_objv110 <- cff_create("jsonlite", cff_version = "v1.1.0")
cat(cff_objv110$`cff-version`)
#> v1.1.0commit

This key is parsed from the “Authors” or “[email protected]” field of the DESCRIPTION file. Only persons with the role “cre” (i.e, the maintainer(s)) are considered.
Example
cff_obj <- cff_create("rmarkdown")
pkg <- desc::desc(file.path(find.package("rmarkdown"), "DESCRIPTION"))

This key is parsed from the “Date” field or, if not present, from the “Date/Publication” field that is present on packages built on CRAN.
Example
# From an installed package
cff_obj <- cff_create("rmarkdown")
pkg <- desc::desc(file.path(find.package("rmarkdown"), "DESCRIPTION"))
cat(pkg$get("Date/Publication"))

This key is parsed from the “doi” field of the preferred-citation object.
Example
cff_doi <- cff_create("cffr")

This key includes all the possible identifiers of the package:
From the DESCRIPTION field, it includes all the urls not included in url or repository-code.
From the CITATION file, it includes all the dois not included in doi and the identifiers (if any) not included in the “identifiers” key of preferred-citation.

Example
# Get cff object from jsonvalidate

This key is extracted from the “Repository” field of the DESCRIPTION file. Usually, this field is auto-populated when a package is hosted on a repo (like CRAN or the r-universe). For packages without this field on the DESCRIPTION (that is the typical case for an in-development package), cffr would try to search the package on any of the default repositories specified on options("repos").
In the case of Bioconductor packages, those are identified if a “biocViews” is present on the DESCRIPTION file.
If cffr detects that the package is available on CRAN, it would return the canonical url form of the package (i.e. https://CRAN.R-project.org/package=jsonlite).
Example
# Installed package
inst <- cff_create("jsonlite")
cat(inst$repository)

# Demo file downloaded from the r-universe
runiv <- system.file("examples/DESCRIPTION_r_universe", package = "cffr")
