dailymed_data_processor

Scripts to download in bulk and process the drug labels data from DailyMed.

For a given SPL index start page and number of pages of the index to process (or) a pre-configured list of DailyMed Set IDs, the scripts parse and obtain the historical set id data and label data for each SPL version. If at least one version of a label set has an association to an NDA application number, the processed labels from the Set ID are saved to MongoDB.

Data Schema

MongoDB Set Up

The connection info for the Mongo DB instance is set in the .env file. This should work for a standard MongoDB set up on localhost. If using a different set of DB configs, this file must be updated.

A sample docker set up for mongo, that maps to localhost:27017 can be found here. This set up also includes the Mongo Express viewer.

Running the Code

Requires a minimum python version of 3.6 to run.

1. pip3 install -r requirements.txt
2. For usage and args, run python3 main.py -h

Usage Examples

• To download the history and process the label data for a pre-determined list of SPL Set IDs, use:

python3 main.py --set_ids_from_file=resources/set_ids.json

• To download the SPL index for a certain page range and process the history and labels for those Set IDs, use:

python3 main.py --start_page=1 --num_pages=2

• Results from intermediate stages (SPL index download and Set ID history download) can be written to disk using the following flags.
  • write_index_data
  • write_history_data

Running Tests

Unit tests are created using Pytest and can be run simply using the following command, from the source root.

$ PYTHONPATH=. pytest -vv

Code Formatting

It is recommended to use the Black Code Formatter which can be installed as a plugin for most IDEs. pyproject.toml holds the formatter settings.
