HDS <=> CQM Models Converter

This repository includes a Ruby Gem that provides a module for converting between the older HDS based models (https://github.com/projectcypress/health-data-standards) and the newer CQM based models (https://github.com/projecttacoma/cqm-models).

See the Gemfile for specific Gem dependency requirements for using this library.

Include cqm-converter in your Gemfile:

gem 'cqm-converter'

Then run bundle install.

The CQM::Converter module provides a class (CQM::Converter::HDSRecord) for converting an HDS Record into a CQM Patient.

Example:

require 'cqm/converter'

# Initialize a new HDS converter. NOTE: This only needs to be done once, and
# should be re-used for every patient you wish to convert!
hds_record_converter = CQM::Converter::HDSRecord.new

# Read in an HDS record JSON file and create an HDS Record object from it.
hds_record = Record.new.from_json(File.read('spec/fixtures/hds/records/eh/1.json')))

# Convert the HDS Record into a CQM Patient.
cqm_patient = hds_record_converter.to_cqm(hds_record)

Also included is a rake task to do this conversion. Just point it to a JSON file containing an HDS Record, and it will output the corresponding CQM Patient JSON to STDOUT.

Note: This rake task is not intended for anything other than experimentation. Any serious use of this library should be programmatic.

Example:

bundle exec rake cqm:hds:to_cqm RECORD=spec/fixtures/hds/records/eh/1.json
