We are flattered. David is aiming for a clone of our Maricopa Learning eXchange, and is added to the list of people requesting a copy of it.
To be honest, as it stands right now, the MLX is rather specialized (our use of colleges for organizing content, some of the file storage methods, LDAP hooks for creating accounts). The real problem is time and staff- the technical staff in my office is 1.5 and one is writing this right now- the bulk of the database and PHP integration development has been done by a brilliant part-time student programmer. This is Maricopa, not Michigan ;-) We just are not able to devote resources into supporting a sharable MLX as it would drain what we have available for its development.
It still sounds stingy.
What I would like to aim to do is provide a documented framework for the MLX, a downloadable version of the mySQL database structure. But someone else is going to have to sort it out for making a clone.
We will give it a try, but do not hold your breath.
That is pretty fair for the creation process. You do not see the submission forms, the user options, the inventory tools. The RSS creation is handled by a timed (cron) script, and uses a simple RSSWriter script for output. Trackback is automatically enabled simply in the template PHP that is output for each MLX item, but there are some background things like the MovableType Standalone Trackback code. We are working on a new content rating feature as well.
We have been updating code behind the scenes to make the system simpler (improved database table structure, streamlined search logic, use of more includes and templates for the output), and I can already see that our database tables have shrunk from 9 to 6.
For an environment, we are very much an open-source platform- Linux Apache, MySQl, PHP. The MLX is scattered across three servers though it need not be- a web server for the front end, a dedicated database server (for this and other projects), another server for the MovableType Trackback engine (just because I had MT on a test server, so that is where it landed), and another one just does the cron tasks for timed updates (actually it just does a CURL to PHP scripts scattered here and there). There is no reason it could not all go on one box.
So to end a long unorganized post, I will take a look into what it would take to boil the MLX down to a more generic version, removing of content and function specific to Maricopa.
But no promises.
