## Description

The IMS Learning Tools Interoperability (LTI) specification provides a standard,
secure method by which a platform (e.g. an Learning Management System) can be seamlessly
integrated with a tool. This library plugin provides the support required to allow
other plugins to enable WordPress to act as either a platform (so that a blog can
be integrated with other content or learning activities) or as a tool (so that a
platform can integrate a WordPress blog into their user experience). For example,
the [open source LTI plugin](https://github.com/celtic-project/wordpress-lti/) supports
enabling WordPress as a tool.

## Installation

This plugin has no user interface; it merely loads the ceLTIc LTI library and any
dependencies so that they are available for use by other plugins. Just activate 
it to have the library loaded for any other plugins you wish to activate which use
it.

## FAQ

### Why do I need this plugin?

If you use a plugin which uses the ceLTIc LTI library, this plugin provides an alternative
from using composer to install this dependent library for each individual plugin,
and avoids the need for server access to do so. It also avoids having multiple versions
of the library installed and makes it easy to keep the library up-to-date when new
releases are made.

### Will my other LTI plugins work without this one?

This will depend upon how the plugins have been written, but the [LTI plugin](https://github.com/celtic-project/wordpress-lti/)
will look for the ceLTIc LTI library either within its own dependent library area
or use one loaded elsewhere, whichever is loaded first. This plugin will not affect
any plugins which do not use the ceLTIc LTI library.
