In inbo/camtraptor: Read, Explore and Visualize Camera Trap Data Packages

Transform Camtrap DP metadata to EML

Description

Transforms the metadata of a Camera Trap Data Package to an EML file that can be uploaded to a GBIF IPT for publication.

Usage

write_eml(
  package,
  directory = ".",
  title = package$title,
  description = package$description,
  creators = NULL,
  keywords = c("camera traps")
)

Arguments

package	A Camtrap DP, as read by read_camtrap_dp().
directory	Path to local directory to write file to. If NULL, then the EML object is returned instead, which can be useful for extended/adapting the EML before writing with EML::write_eml().
title	Dataset title.
description	Dataset description. Will be added after an automatically generated paragraph. Multiple paragraphs can be provided as a character vector.
creators	Dataset creators If NULL then all package$contributors will be added as creators, in the order as listed. If e.g. c("Emma Cartuyvels", "Jim Casaer", "...", "Peter Desmet"), then Emma Cartuyvels, Jim Casaer and Peter Desmet will be set as first, second and last creators respectively, on the condition that their name (title) is present in package$contributors. All other contributors will be inserted at "...", sorted on their last name.
keywords	Dataset keywords.

Value

eml.xml file written to disk or EML object when directory = NULL.
