Overview

About

Maintained by Roberto Villegas-DiazCRAN page ↗GitHub ↗Issues ↗

Provides tools for creating, manipulating and reading Research Object Crates (RO-Crates), a lightweight approach to packaging research data with structured metadata. Includes utilities for metadata generation, entity management, validation and reading existing RO-Crates following the specification https://w3id.org/ro/crate/1.2/.

Changes in 0.1.0

Added higher level function to load RO-Crates from various inputs,

load_rocrate.

Added higher level function to validate RO-Crate and display report with

errors and warnings (if any was found), validate_rocrate.

Defined new checks for RO-Crate validation to ignore system specific

directories (e.g., __MACOSX on macOS).

Refactored functions to streamline checks, including is_rocrate.
Updated get_entity so it takes a vector for id and type, reuses the

shorter vector (only if the length 1), or errors if vectors have different

lengths.

Updated is_rocrate_bag so it returns a boolean value, indicating the

validity of the given RO-Crate bag. Previously, it returned a path to the

root of the RO-Crate.

Updated unbag_rocrate to return the path to RO-Crate root _visibly_.
add_entities() is deprecated. Use add_entity() instead.
load_rocrate_bag() is deprecated. Use load_rocrate() instead. Note that

validation must be done as a separate step using validate_rocrate().

read_rocrate() is deprecated. Use load_rocrate() instead.
remove_entities() is deprecated. Use remove_entity() instead.
entity(x=) renamed to entity(id=).

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("rocrateR", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("ResearchObject/ro-crate-r")

Development version from ResearchObject/ro-crate-r. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-rocrater

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-rocrateR

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-rocrateR

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
