Biolink Beacon

A knowledge beacon implementation for the Monarch Biolink API (https://api.monarchinitiative.org/api/), a biomedical data source containing information about diseases, phenotypes, and genes, and the relations between them.

Getting the Project

The biolink-beacon package is not yet available through PyPI, thus, to install, clone this repo using git.

git clone https://github.com/NCATS-Tangerine/biolink-beacon

# ... then  enter  into your cloned project repository
cd biolink-beacon

Installing and Running without Docker

First, create a virtual environment:

python3.7 -m venv venv
source venv/bin/activate

The application expects to use a Python release 3.7.4 or newer binary (note that your binary in the venv command above may just be typed as python3.7, python3 or even just python but the python --version should resolve to 3.7.4 or better).

Next, make sure that your pip version is 3.7 compliant. It is also a good idea to ensure that you have the latest version of pip for your venv:

python -m pip install --upgrade pip

Site Configuration

The beacon server runtime relies on a swagger.yaml file sitting under server/swagger_server/swagger. Two templates are currently provided - one assuming a development 'localhost' host and root basepath; the other for NCATS endpoint deployment. Copy over one or the other template into a file named swagger.yaml within the same directory.

Dependencies

Then, run the following commands within the biolink-beacon directory. Note that errors may result if ontobio and connexion[swagger-ui] are not installed separately.

pip install ontobio
pip install -r requirements.txt
pip install connexion[swagger-ui]
pip install client/
pip install server/
cd server/
python -m swagger_server

Running with Docker

docker build -t ncats:biolink .
docker run -d --rm --name biolink -p 8080:8080 ncats:biolink

This will run the Docker container named 'biolink' as a daemon on port 8080 (or 8078 in the NCATS deployment).

Navigate to http://localhost:8080/ui/ in your browser to see the Swagger UI or whichever URL to which you have aliased the server (e.g. for NCATS, might be something like https://kba.ncats.io/beacon/biolink/ui/).
