 A repository for the analysis of various RADx data dictionaries.  The repo contains a folder called "curated" that contains a collection of cleaned data dictionaries by Data Collection Center (DCC).  To process the data dictionaries run the "process-data-dictionaries.sh" script.  The processing will produce a series of folders containing intermediate processed data dictionaries and then a merge of all data dictionaries in a file called `merged.csv`.
