In rocrateR: Tools for Creating and Manipulating RO-Crates

Check if path points to a valid RO-Crate bag

Description

Check if path points to a valid RO-Crate bag

Usage

is_rocrate_bag(path, algo = NULL, bagit_version = "1.0")

Arguments

path	String with full path to a compressed file contain an RO-Crate bag, see bag_rocrate for details. Alternatively, a path to a directory containing an RO-Crate bag.
algo	String with algorithm used to generate the RO-Crate bag (default: NULL, which auto detects the algorithm from the ⁠manifest-<algo>.txt⁠ file, inside the bag). See digest for more details on valid algorithms.
bagit_version	String with version of BagIt used to generate the RO-Crate bag (default: "1.0"). See \Sexpr[results=rd]{tools:::Rd_expr_doi("10.17487/RFC8493")} for more details.

Value

Returns a boolean flag to indicate if the given RO-Crate bag is valid.
