ceLTIc LTI Library

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 supports enabling WordPress as a tool.

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.
