A data package forms a collection of data objects and metadata enabling understanding, use, and citation of a dataset. Metadata play an important role in understanding each object and how they relate to each other. EAL works for all digital object formats and has been used by the Environmental Data Initiative (EDI) to create and manage over 500 data packages for a nearly equal number of researchers. Revising data packages with EAL is easy but requires some forethought about file organization.
A useful organization scheme is a single directory for each data package containing:
template_directories() to create this organization
An even simpler organization scheme, albeit more cluttered, is a
single directory containing all files belonging to a data package. A
third option is to customize file location, use the
eml.path arguments of EAL
