Nick FreearAccessibility, internationalization, web dev, Moodle and other stuff

I was tipped off about Nomensa's player, newly open sourced (thanks Chetz), and ever curious, I thought I'd take a look.

I came across version 1 of the player last year, and I must say at the time I was a bit bemused. It seemed to be a thin wrapper around either YouTube, or the JW Player (I can't remember which), and Nomensa weren't upfront about saying so.

Note, I'm not going to go into the accessibility aspects here, but instead concentrate on how the open-source project itself is presented.

Over the past 12 months I've created a number of contributed plugins for Moodle. Moodle is an open-source e-learning or virtual learning environment (VLE), that teachers, lectures and trainers can use to enhance face-to-face and blended teaching. It is also used by a number of large institutions like The Open University for distance education.

I have been asked to present the reasoning behind our choice of CodeIgniter over Drupal for the OU player/ OU embed projects.

I will argue that the OU player project provides an ideal case study for why The Open University, including the central IT providing departments should not adopt a one-size-fits-all approach to the choice of information technologies. At present, I think they are in danger of doing this. You may also be interested in Juliette Culver's post, Why we moved from Drupal to CodeIgniter, and Will Wood's post, Agile Ballooning.

First, some background. CodeIgniter is a minimal model-view-controller PHP framework. It is open source, makes full use of the object-oriented programming paradigm, offers database abstraction, an ORM (object-relational-model) layer, and various extension mechanisms including libraries, hooks and helper functions. By default, templating/ views are implemented in PHP, though an alternative templating system such as Smarty could be plugged in. There are many third-party plugins available, and it is a simple matter to plugin other libraries, for example parts of the Zend framework. As a low level framework, its benefits are a shallow learning curve, the promotion of maintainable, well-structured code, small footprint, performance and flexibility (http://codeigniter.com).

Between the Wednesday 8th and 13th of June we are conducting usability and accessibility testing for the OU media player project, at The Open University's campus in Milton Keynes.

We are seeking test subjects for 1 to 1.5 hours testing. Travel expenses and a fee will be paid. Anyone can come forward, including those who are deaf or hard of hearing, those who have dyslexia and those who use a screen reader.

Thanks, Nick

Enjoy! (May 2011)

In spare moments in the past few weeks I've been revisiting browser search plugins. I've created plugins for CloudEngine/ Cloudworks, iSpot, the Journal of Interactive Media in Education, and The Open University. I thought I'd jot down what they are, why they're useful and how I'm integrating them into my projects.

I've proposed a mini-project here, for IET to host an experimental embedding service on behalf of The Open University. This will serve a similar purpose to Embed.ly (api.embed.ly) and Oohembed (oohembed.com), and act as a proxy on behalf of other embed or service providers, for example, YouTube, LAMS, Prezi and Google Docs forms.

Two point before I start:

1. I'm not a lawyer, so this blog post does not constitute legal advice. If you need help, contact a lawyer who specializes in software and content licensing. I accept no liability...
2. I'm absolutely not against Creative Commons Licenses, for content. Indeed on recent projects I've made extensive use of CC licensed text, images and so on, and this blog is CC licensed. Just not for software...

So, you've written some software and decided to share it with others - congratulations! You may be contemplating licensing it with one of the range of Creative Commons Licenses... Hold on! In this blog post, I'll explain why this is a really bad idea, both for you and the community. And I'll hopefully dispel some myths and point you to other sources of information.

A colleague of mine asked me the other day at Dev8D if there was a list of all of The Open University's free/ open source contributions. I had to say that as far I knew there wasn't.

So, I've started this list on Delicious, using the tags ou opensource project. Note, I have also added tags for license where I can find one (eg. gpl for GNU General Public License), OU department (lts), technologies (svn, java) and wider projects (moodle).

Note that the tag ou does not necessarily imply that The Open University is the founding, sole, or main contributor to a project!

Feel free to add anything that I've missed. It's interesting to see what licenses we're using, what projects we're contributing a lot to (Moodle fairly obviously!) and so on. Enjoy...!
