r2ddi is supposed to produce DDI 2.5 compliant XML from datasets in CSV, Stata and SPSS format.
Currently, only the import for Stata is fully implemented.
Simple to use
To extract the metadata from multiple Stata files (all located in one directory) into DDI-compliant XML files, the following two lines of code are sufficient:
library("r2ddi") dir2xml(path_in="your/path/here", path_out="your/path/here")
