PyLTI provides Python Implementation of IMS LTI interface that works with edX

Project Description

PyLTI - LTI done right

PyLTI:Python implementation of LTI
Author:MIT Office of Digital Learning

PyLTI is a Python implementation of the LTI specification [1]. It supports LTI 1.1.1 and LTI 2.0. While it was written with edX [2] as its LTI consumer, it is a complete implementation of the LTI specification and can be used with any learning management system that supports LTI.

A feature of PyLTI is the way it is used in the creation of an LTI tool. PyLTI is written as a library that exposes an API. This separation of concerns enables a developer to focus on the business logic of their tool and support of their framework of choice.

To demonstrate this usage, there are also a collection of example LTI tools written to support different Python web frameworks.
