# FHIR Transformer Specification

## Introduction

This document describes a portable transformation engine 
that can be used to convert different kinds of source 
material into a FHIR repository. 

## Components 

grahamegrieve

Use cases

This document describes a way of granting an application access to data on a set of patients. 
The application can request a copy of all pertinent (clinical) access to the patients in a 
single download. Note: We expect that this data will be pretty large. 

Authorizing Access

Access to the data is granted by using the SMART backend services spec 
(url: http://docs.smarthealthit.org/authorization/backend-services/).
