e-Learning Development Phase One: Digital Library*
Hi my name is Boon Low, I’m a developer from the NA3 training team at the UK national e-science
I’m here to talk about the EGEE digital library. The library was first mentioned at the EGEE conference in Athens, a few years ago, as a support service for NA3 activities. Since then it has undergone several cycle of developments. So today, I will report on these developments and also will talk about about how you can use it.

Provides alternative training approaches
Self-paced, peer-to-peer learning
“I prefer to learn whenever I need to and online!”.
*
e-learning is the underlying basis upon which we are building the digital library. This is because it can help us to address some of our training requirements. Firstly, it could enhance the accessibility to courses, with persistent availability. Some of the survey that we have done in the past suggest that some learners would actually prefer not to travel to training events if there is a way for them to learn whenever they need to and online. Of course, there is still a big question mark about how effective and how feasible to it is to provide grid training online, the availability of training infrastructure. But the question is being answered. For example, by the t-infrastructure work that has just been described by Emidio, and the recent the Online Winter School run by the ICEAGE project. Robin has given a talk about just the winter school in the Monday session. You are welcome to talk to him if you have missed the session.
e-learning can also provide alternative training approaches, for example a 5 week online intensive course like the winter school or a totally self-paced course used by the learners themselves at their own time.
If it is not possible to provide an entire course online due to feasibility or resourcing issues, a particular strategy is to facilitate only part of it for example pre-requisite or induction type of training. This would free up resources for more advanced type of training provisions. This is very relevant right now as EGEE aims to reduce efforts to maintain the project and to meet the expectations of growing user communities.

e-Learning Services
*
This is a diagramme showing a range of e-learning services based on the e-Learning Framework. As you can see the scope is quite diverse.

Initial & main NA3 effort focus on facilitating training resources repository
Digital Library
*
The initial efforts of NA3 was to provide a repository for sharing training resources, so that the trainers do not have to spend a large of amount times in developing resources and concentrate on teaching.
This repository services to the resource discovery, the search & browse functionality of e-learning. The repository has been developed extensively to this day.
It is still one of the main function of the NA3 support services.

+ two other interim developments
This is the next version of the repository providing more content and improved search navigation. You can also search the content via basic metadata according to the ISO Dublin Core schema.

Metadata search
Full-text search
*
You can search resources by metadata or in full-text mode just like Google.
One of the function that we have improved is the resource type links at top of the page. The links provide both filtering or browse functionalities, depending on whether there is a keyword is entered in the search box. You can also cross-search content of digital libraries from other of grid projects such as ICEAGE and OMII-Europe.

Users can use web UI to create personal notification channel
*
There is also a RSS notification service that is dynamically generated for all search queries. Users can use the library interface to create personal notification channels, for example they can search for a particular subject and bookmark the feed, subsequently get alerted when new content related to the subject is available in the digital library.

RSS + MP3 (audio) = Podcasting, iTunes and iPod integration
*
Since the library contain Mp3 content, the RSS feed can be used for podcasting. This means users could download the audio content to the MP3 player via software such as iTunes. We have also made all the audio files from the recent summer school on grid computing as a special podcast on iTunes for people to subscribe to.

The digital library URL:
http://library2.nesc.ed.ac.uk:8080/fedora/services/access?wsdl
Based on a range of open source systems: Fedora, Apache Solr, Orbeon Forms, Blacklight
Technology: Java, Ruby on Rails + AJAX (new beta)
Digital Library
*
So far there are various types of resources available from the digital library. A majority of them are presentations that we gathered from the training events. We are always looking to add more useful content and particularly repurpose existing content for better online use. For example, we have repurposed the audio track from the international summer school and synchronised it with the presentation and reuse the resources in the winter school.
Please a take note of these URLs well. We are revamping the library once again. I will take a little bit more about it later. A beta version of new digital library is online. You are welcome to take a look at it and provide any feedback.
The library content is accessible via SOAP web services, and it is based on a range of open source systems and built on a platform with a mixture of Java, Ruby on Rails and AJAX technologies.

With the notification service, we have ticked a more box for e-learning.

This is a screenshot of the metadata management service. You use the form to tag metadata based on the ISO metadata schema, Dublin Core, providing bibliographic and educational data such as learning objectives, instructional details.
The metadata form is AJAX based. You can easily add or remove form widgets for metadata fields that can hold multiple values.

Login
Create entry in the digital library by filling minimum metadata fields
Add URL or upload a file
+
*
You can create entry into the digital library easily in 3 steps: logging, then creating the entry by filling in a couple of metadata fields and then either add a URL of submit a file
The content and metadata can also be updated or enhanced later via the metadata form interface by any authenticated users. The library also maintain a history of all edits providing a way to revert back an older version of metadata and content if it needs be.

Digital Library 2.0
A better digital library to incorporate outputs from past initiatives such as ICEAGE
Focus on broader definition of digital library:
A “digital library” is fundamentally a resource that reconstructs the intellectual substance and services of a traditional library in digital form
*
As I have mentioned earlier, we are currently revamping the digital library once again, as 2.0 version, to provide better services and to incorporate the useful outputs from past initiatives such as the ICEAGE project.
We will focus on the broader definition which ascribes the digital library as a resource that reconstructs all aspect of the traditional library in digital form.
This means going moving beyond repository centric functions, and towards providing an environment that is conducive to training, encourage people to interact and share stuff.
EGEE-III INFSO-RI-222667
Federate content of digital library in diverse communities
Federation = Interoperability: interfaces (UI and APIs) and content standard
Digital Library 2.0: Well?
How would we achieve this? Well, I’m sure you have heard of Web 2.0. We hope to explore the Web 2.0 ways of working for the digital library, looking more into user-centric function and user-generated content. We will also make use of dynamic UI, to provide enhanced user experience.
Since content is still key to the digital library, we will continue to find ways to repurpose and federate content with sources from various communities such as other grid education initiatives and content providers.

We have started work on the new version already. It now has a look and feel that is more coherent with the EGEE project website.
