#pyccda

A Python library for CCDA XML files. Part of the BlueButton+ health data liberation initiative

##Development notice

This project is under development and is not fully-featured yet. However, pyccda is capable of parsing CCDA XML files and converting them to structured ProtoRPC messages or simplified CSV documents, which can be used to pipeline the data into data analysis tools.

##Usage

Before using, run pip install -r requirements.txt to install dependencies.

import pyccda
ccda = pyccda.CcdaDocument(open('ccda_file.xml'))

# Returns CCDA represented as a simple CSV, which can be
# useful to load data into an external data analysis tool.
ccda.to_csv()

# Returns CCDA represented as a protocol buffer message, for easy
# data access and transfer between systems.
ccda_message = ccda_doc.to_message()

# Easily access health information using the protocol buffer message.
ccda_message.allergies
ccda_message.demographics
ccda_message.immunizations
ccda_message.labs
ccda_message.medications
ccda_message.problems
ccda_message.procedures
ccda_message.vitals

##Running tests
