OPENDF: Stata module to work with Open Data Format files in Stata

The opendf package provides functions to work with the Open Data Format (ODF) in Stata. The ODF is an open, non-proprietary, multilingual, metadata-enriched, and zip-compressed data format designed to meet the FAIR principles for scientific data management and stewardship. It is platform-independent and open-source, ensuring broad accessibility and usability. The package provides three core functions: opendf read, opendf docu, and opendf write. opendf read: This function imports ODF files into Stata, loading both data and associated metadata into the environment. The metadata is stored in labels and characteristics within Stata. Users can specify the additional parameters rowrange, colrange, clear, save, replace, and verbose. opendf docu: This function displays metadata for the dataset or specific variables in a user-friendly style within Stata. When called without arguments, it shows metadata for the entire dataset. When provided with a variable name, it displays metadata specific to that variable. The function also supports a languages argument to display metadata in one or several specific languages. opendf write: This export function allows users to save Stata datasets in the ODF format. It captures all metadata stored in labels and characteristics that are compatible with the ODF specification and writes it to an XML file within the ODF zip file. The function requires the file name or path for the new ODF zip file and offers additional arguments such as input, languages, variables, replace, and verbose.
