A simple python script to copy/scrap/crawl a FHIR repository to another one.

The script is written in Python 3.

Install it from pip

python -m venv .venv
source .venv/bin/activate
pip install git+
cp .venv/bin/ .

Edit for your needs.

Run it :


How to run it from git

First clone this repository.

git clone

You can install it quickly into a Virtual Environment. First, you need to move to the source folder and create an Virtual Environment (all commands are for Unix-based OS and may need tweaking on Windows):

python -m venv .venv
source .venv/bin/activate

On Windows without Windows Subsystem for Linux, you will need to change the last command to .venv\bin\activate.bat.

These commands will create a new directory, visit it, create the virtual environment, and activate it. Then you can install the dependencies.

pip install .

Before running it, you can refere to the configuration.

Now you can run the app.

python .venv/bin/

How to configure it

Edit the file to configure the variable in main.

### Source Repository urlClient = "http://localhost:52773/fhir/r4/" ### Source authorization heard source_authorization=None ### Destination Repository urlServer = "http://localhost:32783/fhir/r4/" ### Destination authorization heard target_authorization=None ### List of resource to fetch ### If None, the script will fetch all available resources p_resources=None ### Limit the number of resource to fetch p_limit=100

How it works

By default the algorithm will read the metadata of the source.
For each resource found, it will retrieve it, transform it and insert it in the target with the same ID.

The transformation is done by the transform function, it is based on the keys/values of the resource. In this example, the transformation ignores the endpoint keys and transforms the id values.

In case of error, the script moves to the next resource.

Future Development

If this script is successful, I will try to optimize its development for example by adding parameters with the python click module and maybe publish it on Pypi.
