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
