CRAFTS (Configurable REST APIs For Triple Stores) is a configurable generator of REST APIs to simplify access to triple stores. CRAFTS allows knowledge engineers to configure REST APIs over multiple triple stores. Web developers can then use a CRAFTS API to read and write Linked Open Data. CRAFTS automatically handles the translation of API calls into SPARQL queries, delivering results in JSON format. The API of CRAFTS is uniform, domain-independent, and described with the OpenAPI specification.

CRAFTS is a Node.js web application. Edit the data/config.js file to parametrize your deployment (parameters are auto-descriptive).

Assuming npm is installed, launching CRAFTS just requires the following two commands:

$ npm update
$ node app.js
