Thalamus: The GNU Health Federation Message and Authentication Server
=====================================================================

The Thalamus project provides a RESTful API hub to all the GNU Health 
Federation nodes. The main functions are:

#. **Message server**: A concentrator and message relay from and to  
   the participating nodes in the GNU Health Federation and the GNU Health
   Information System (PgSQL). Some of the participating nodes include 
   the GNU Health HMIS, MyGNUHealth mobile PHR application,
   laboratories, research institutions and civil offices.

#. **Authentication Server**: Thalamus also serves as an authentication and
   authorization server to interact with the GNUHealth Information System


Thalamus is part of the GNU Health project, but it is a self contained, 
independent server that can be used in different health related scenarios.

Installation
------------
Thalamus is pip-installable::

  $ pip install thalamus

  
Technology
----------
RESTful API: Thalamus uses a REST (Representional State Transfer) 
architectural style, powered by 
`Flask <https://en.wikipedia.org/wiki/Flask_(web_framework)>`_ technology

Thalamus will perform CRUD (Create, Read, Update, Delete) operations. They
will be achived via the following methods upon resources and their instances.

* **GET** : Read
 
* **POST** : Create
 
* **PATCH** : Update
 
* **DELETE** : Delete.

The DELETE operations will be minimal.
  

JSON: The information will be encoded in `JSON <https://en.wikipedia.org/wiki/JSON>`_ format.

Resources
---------

Some resources and end-points are:

* People (/people)

* Pages of Life (/pols)

* DomiciliaryUnits (/domiciliary-units)

* PersonalDocs (/personal_docs)


Running Thalamus from a WSGI Container
--------------------------------------
In production settings, for performance reasons you should use a HTTP server.
We have chosen `gunicorn <https://gunicorn.org/>`_ . 

For example, you can run the Thalamus application from uWSGI as follows.
The default configuration file uses secure (SSL) connections::

  $ gunicorn --daemon -c etc/gunicorn.cfg thalamus:app

For development, if you want to run it directly from the Flask Werkzeug server,::

  $ python3 ./thalamus.py


Examples
--------
**Command-line, using httpie**

Retrieve the demographic information of person::

  $ http --verify no --auth ARGBUE111FAV:freedom https://federation.gnuhealth.org:8443/people/ESPGNU777ORG


Yields to::

**Using Python requests**::

  >>> import requests
  >>> person = requests.get('https://localhost:8443/people/ESPGNU777ORG', auth=('ITAPYT999HON', 'gnusolidario'), verify=False)
  >>> person.json()
    {'_id': 'ESPGNU777ORG', 'active': True, 'biological_sex': 'female','dob': 'Fri, 04 Oct 1985 13:05:00 GMT',
    'education': 'tertiary', 'ethnicity': 'latino', 'gender': 'female', 'lastname': 'Betz', 'marital_status': 'married',
    'name': 'Ana', 'password': '$2b$12$cjrKVGYEKUwCmVDCtEnwcegcrmECTmeBz526AAD/ZqMGPWFpHJ4FW', 'profession': 'teacher',
    'roles': ['end_user']}

**Note on roles**
The demo user "ITAPYT999HON" is a health professional (health_professional role),
so she has global access to demographic information. 

The user "ARGBUE111FAV", password "freedom". This is the "root" user for the demo database. 

Check the ``roles.cfg`` file for examples information about roles and ACLs.
