Functionality of 'add_meta_data_for_dictionary' should be updated

As we update and improve our data to analysis pipeline approaches, we should also update the functionality of 'add_meta_data_for_dictionary'.

  • Incorporate REDCap data types and checks based on 'validate_var_name'
  • Incorporate new default 3-letter abbreviations for categories (e.g., in addition to 'SSS', 'INV', etc., we can include 'INC', 'SCR', etc.) based on standardized REDCap forms.
  • Allow greater flexibility in data dictionary columns/entries; for example, allow entries to be excluded via the value 'NULL'.
  • Consider creation of a 'data_dictionary' R class that interfaces with various generic methods for flexible creation, access, and manipulation of data dictionary entries.
