MitteLTI

MitteLTI is a software library designed to facilitate the integration of Learning Tools Interoperability (LTI) into web applications. LTI is a standard developed by the IMS Global Learning Consortium that allows learning platforms, such as learning management systems (LMS), to connect with external tools and services. MitteLTI aims to simplify the process of implementing LTI according to the LTI 1.1.1 and LTI Advantage specifications.

The library provides developers with tools to handle LTI launch requests, validate signatures, and manage user data passed between the LMS and the tool. It supports various aspects of the LTI protocol, including authentication, authorization, and the passing of course and user context. MitteLTI is often used by developers who are building educational tools or plugins that need to interact seamlessly with common LMS platforms like Canvas, Blackboard, or Moodle.

Key features of MitteLTI typically include mechanisms for parsing LTI parameters, generating LTI launch URLs, and managing the security aspects of the LTI handshake. By abstracting away some of the complexities of the LTI protocol, MitteLTI enables developers to focus more on the educational functionality of their tools rather than the intricacies of the integration standard. The library is usually available as an open-source project, allowing for community contributions and adaptation.
