Drop additional LICENSE file?

Do we need both license files?

I imagine by both you mean https://github.com/FederatedMethods/dsROCrate/blob/main/LICENSE and https://github.com/FederatedMethods/dsROCrate/blob/main/LICENSE.md, in which case, the answer is yes! The former is the CRAN standard to specify a Copyrights holder and year; whilst, the latter is a 'human-friendly' overview of the package's license. This is the standard for R packages. See https://usethis.r-lib.org/reference/licenses.html for details.
