hydrus Build Status

hydrus is a set of Python-based tools for easier and more efficient creation of Hypermedia driven REST-APIs. hydrus utilises the power of Linked Data to create powerful REST APIs to serve data. hydrus uses the Hydra(W3C) standard for creation and documentation of its APIs.

Start-up the demo

  • with Docker and docker-compose installed, run docker-compose up --build
  • open the browser at http://localhost:8000/api/vocab

You should be displaying the example API as served by the server.

Add your own Hydra documentation file

To serve your own Hydra-RDF documentation file:

  • create a doc.py file as the ones in examples/ directory containing your own ApiDoc
  • set the APIDOC_REL_PATH variable in docker-compose.yml. This should the relative path from the project root
  • start-up the demo as above.

You should be displaying your API as served by the server.

Features

hydrus supports the following features:

  • Be a client that understands Hydra vocabulary and performs basic CRUD operations on data in a Hydra supporting server.
  • Be a generic server that provides the required data and metadata (in the form of API documentation) to a client over HTTP.
  • Be a middleware that allows users to interact with the server using Natural Language which is a processed machine consumable language. (under development)

Requirements

The system is built over the following standards and tools:

  • Flask, a Python-based micro-framework for handling server requests and responses.
  • JSON-LD as the preferred data format.
  • Hydra as the API standard.
  • SQLAlchemy as the backend database connector for storage and related operations.

Other than this, there are also various Python packages that hydrus uses. Running python setup.py install installs all the required dependencies.

NOTE: python3 should be used, not python2.

Demo

To run a demo for hydrus using the sample API, do the following:

Clone hydrus:

git clone https://github.com/HTTP-APIs/hydrus

Change directory and switch to the develop branch:

cd hydrus

git checkout -b develop origin/develop

Install hydrus:

pip install .

or

python setup.py install

and run the server:

hydrus serve

The demo should now be running on http://localhost:8080/serverapi/.
