  • A generic server that can serve required data and metadata(in the form of API documentation) to a client over HTTP.
  • A middleware that allows users to use the client to interact with the server using Natural Language which is processed machine consumable language. (under development)


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.
