Koseu solves a number of important use cases:

• A Learning Object Repository with seamless integration into previous-generation LMSs
• An independent open source, highly scalable, extremely flexible MOOC hosting platform
• A Next Generation Open Source Learning Management System

Eventually, this will be the best LMS, LOR, and MOOC hosting platform in the world. But for now this is just a README file so I can get started writing the code.

If you want to see Koseu in action visit these web sites:

• Python for Everybody www.py4e.com
• Web Applications for Everybody www.wa4e.com
• The Tsugi project - www.tsugi.org

Actually most of the koseu code that already exists lives in https://github.com/tsugiproject/tsugi - the Koseu code will be refactored out of the Tsugi Management Console, rewritten to be more OO, and moved into this repository.

Koseu is written as a Silex (http://silex.sensiolabs.org/) application so it has pretty URLs, routing, nice OO patterns and all that hipster stuff.

The basic idea of Koseu is that it is "embedded" into a static web site. So the web site has things like images, PHP files, HTML, PowerPoint, tools etc that are just served like normal Web 1.0 files. When you add Koseu to a web site, it makes URLs like https://www.py4e.com/lessons start to appear. First you install Koseu using the following composer command:

composer require --dev koseu/lib

Then you need to route non-file, non-folder urls to koseu.php using a .htaccess similar to the following:

FallbackResource koseu.php

Then you need to add the koseu.php to your web site:

 <?php
 define('COOKIE_SESSION', true);
 require_once "tsugi/config.php";

 // Pull in the Koseu LMS (/lessons, /map, /badges ...)
 $launch = \Tsugi\Core\LTIX::session_start();
 $app = new \Koseu\Core\Application($launch);
 $app->run();

That is (or soon will be) it. Then you just add Koseu URLs in your web content to Koseu tools. For now, you still need to install and setup the Tsugi Management Console (https://github.com/tsugiproject/tsugi). But over time the Tsugi management console will also move into composer so as to deliver in the promise of "installing an LMS" in 10 lines of code.

코스 is the Korean word for "Course" and www.koseu.com and www.koseu.org were still available :)
