Virtual worlds are getting quite a bit of attention at work at the moment and for good reason. Clearly there is a huge potential for their use in education and momentum in this area is really building. Like many I have experimented a bit with platforms like Second Life but am now wanting to do more. Second Life, while being great for some uses may not meet all requirements for everyone. I am particularly interested in installing my own virtual world and there are a number of options. Once installed, the first thing I need to do is start building or populating my virtual worlds and so far this is not easy for a novice. A lot of effort seems to be required to start creating appealing and useful artefacts for these worlds. What I’d really like to do once I have created something is to be able to transport it into another virtual world so that I can get some re-use out of it. Some sort of standards and mechanisms for such transportation would be great here. Interoperability specs here we come!
So it was with interest I read this post on the readwriteweb blog.
‘Teleporting’ sounds a lot more interesting than ‘harvesting’ (metadata). Sharing and re-using assets from virtual worlds is going to be very important and I look forward to hearing more about work in this area (perhaps we will see an OpenSocial for virtual worlds).

Cheers,
Jerry.

From the Learning Futures Eiffel team blog here’s a nice introduction on standards to consider for ePortfolios. It gives a nice summary of the major ePortfolio specific standards to consider and importantly, mentions related specifications such as OpenSocial which I believe those interested in ePortfolios should start to at a minimum, become familiar with. From the article:

Today, even if few ePortfolio suppliers are engaged in the implementation of existing specifications, those doing it generally do so within the context of a specific community, using what is called application profiles, i.e. an adaptation of a base specification to the particular requirements of this community. This adaptation adds a level of complexity to the issue of interoperability, as different application profiles of the same base specification do not necessarily interoperate…

Our own experience in this area certainly backs this up. Some time ago, we developed an Employability Skills ePortfolio and used the IMS ePortfolio specification to build it. The IMS specification itself is (well) quite comprehensive to say the least which added some complexity to our work but in developing a profile specifically for employability skills, we in effect lost interoperability with other IMS ePortfolio conformant applications unless they used the same profile as us (highly unlikely).

In the past I have discussed the need for simple to implement standards and concentrated on specifications such as RSS, Atom and microformats. The Learning Futures article references hResume, an interesting format used by LinkedIn. Compare the definition for that with a heavy duty specification and see which one you would rather implement.

Google, the Internet Society of Australia (ISOC-AU) and the Sydney Linux User’s Group are hosting an event for the first annual Document Freedom day on Wednesday 26th March at the Sydney Google offices. From the document freedom site:

“The Document Freedom Day (DFD) is a global day for Document Liberation with grassroots action for promotion of Free Document Formats and Open Standards in general. The DFD was initiated and is supported by a group of organisations and companies, including, but not limited to the Free Software Foundation Europe, ODF Alliance, OpenForum Europe, IBM, Red Hat and Sun Microsystems, Inc.

On 26 March 2008, the Document Freedom Day will provide a global rallying point for Document Liberation and Open Standards. It will literally give teams around the world the chance to “hoist the flag”:”

For more information about the event in Sydney, see here.

At education.au we are keen to use, showcase and promote open standards in general, but we obviously have a specific interest in those that affect or can be utilised within education. This event in particular is well timed in terms of what is happening at the moment with open document formats and the standardisation process. Many will have heard about OOXML and possibly the fast tracking of the Draft International Standard 29500. However, if you are not, simply try googling OOXML. The debate over this issue is intense, to say the least. Trying to find an unbiased view can be challenging. Here are a couple of links that are worth reading but as with anything that is written, are written through the eyes of the writers/contributors.

• Office Open XML - Wikipedia
• ODF/OOXML technical whitepaper

Cheers,

Jerry

From Stephen Downes’ blog, notification that the IMS Global Learning Consortium is exploring the use of Creative Commons licensing in its interoperability specifications. The press release from IMS doesn’t go into a great deal of detail other than plans to run a pilot project under a form of Creative Commons licence. It will be interesting to see what form that licence takes. It sounds like it could be a great initiative and I look forward to more details coming out.

Some more news on standards. For those interested in SCORM, ADL and SIFA have just announced a partnership that will be looking at how to integrate SCORM into school applications that are using the Schools Interoperability Framework (SIF). A new version of SCORM that is ‘100% based on open standards’ (called Core SCORM) will be developed. More information can be found here and here. I look forward to more information as it becomes available.

Interesting post from Tim Hand got me to thinking about this one. From Tim’s perspective, the standards arena seems to have stalled a bit (if I’m reading correctly). When compared to what’s happening in Web 2.0 with new services and technologies just powering ahead. Try to keep up with what’s happening in the world of mashups alone and it’s staggering. There is interoperability (of a kind) everywhere. Developers are connecting up all sorts of apps, data sources etc to deliver new, innovative services. In doing this they are not dependent on cumbersome, complex standards. We recently did some research on standards in the area of ePortfolios and one of the major findings from that was the impact that Web 2.0 was having in that area. It was hard to find ePortfolio implementations (other than vendor software) that were using standards such as IMS ePortfolio but many of the implementers were interested in using RSS and other lightweight specifications in their implementations. They could easily consume content from other sources and also publish/syndicate their content very easily. Simple specs and simple services enable them to include functions from other sites into their ePortfolios (eg using Flickr to hold images of your work). Students also saw services such as myspace and Facebook as better places for them to have their ePortfolio (there were some interesting variations on this though).
So what does this mean for the formal world of standards and specifications. The very nature of the standards process is a slow one. A great deal of work goes into the development of a standard/specification which involves development work, collaboration, reviews, (public) comment, ratification and so on, all of which takes time. Time unfortunately is not ‘Standards’ best friend in the frenetic, fast pace of the Web 2.0 world. As the rate of change increases in both speed and sheer number of new services, it seems to me that the slow paced standards process faces a real challenge to keep up.
