Accessibility 2.0 – A Million Flowers Bloom

On Tuesday, I was at the Accessibility 2.0 conference hosted by AbilityNet. The conference introduced some important topics currently effecting web professional, touching on accessibility with Silverlight, support of HTML5 and WAI-ARIA on assistive technologies as well broader discussion on accessibility on mobile devices. The events were organised into a series of presentation and discussion panels from a group of distinguished speakers

Christian Heliman keynote “Finite Incatatem – Accessibility is not black magic” slides are available on slideshare, the main focus of his presentation was to increase the profile of universal design (accessible design/development practices) in web development and particularly to include accessibility early on the development phase. He also, introduced the work done on Easy YouTube player an attempt at making YouTube videos more accessible to people with disabilities. Further presentation on making multimedia accessible is presented by Open University at Techshare 2009, with an interesting comparison of media players including easy-youtube.

Silverlight accessibility was touched on by Saqib Shaikh (Microsoft), who introduced Silverlight as cross platform, cross browser, open standard and demonstrated accessibility features built into the platform such as colour contrast, keyboard access and the potential to create accessible videos. A series of demonstration were made showing how screen readers (NVDA) interacted with an open source accessible Silverlight media player particularly reading closed captions/audio descriptions from W3C timed text files associated with the video.

Steve Faulkner presented on HTML5 and WAI-ARIA, he reported current browser support for HTML5 is limited, with Microsoft Internet Explorer yet to fully support this. HTML5 form controls were poorly supported by assistive technology at present, with very few exposing even basic keyboard access. The HTML5 canvas element was criticised for being an accessibility black hole, since no content is exposed to assistive technologies, although workaround for producing accessible content have been suggested. Video element was also criticised for lacking support for caption/subtitling at least in the first release of the standard.

Steve compared WAI-ARIA support reporting support was much better across browsers and assistive technologies such as JAWS, NVDA and ORCA. JAWS public beta shows support for a variety of roles from Drag-drop to ARIA Live Region used commonly with AJAX. He also demonstrated the use of landmark roles to mark specific regions of a page and quaintly described as “super charged skip to content links”.

Two discussion panels were held during the day, the first was on “Accessibility beyond the desktop discussion” and second on “To comply or not to comply? That is the question”. The first considered the impact of mobile technology on accessibility and considered how content could be presented accessibly to wide group of people. The second considered the challenges of producing accessible web solutions within the constraints of a work environment, presenting the issues faced by developers and offered recommendations. Detailed transcripts of the discussion panels to follow shortly with links to slides as and when published by AbilityNet.

Spreading the word about YODL

After a year of developing and implementing the pilot phase of YODL, the york online multimedia repository, we feel we have useful experience to share with other people working in this area. In July Julie Allinson and Elizabeth Harbord published an article in Ariadne, a Web magazine aimed at information professionals in archives, libraries and museums . The article outlined the progress of the project from its inception through to its actual implementation. (http://www.ariadne.ac.uk/issue60/allinson-harbord/). To accompany this, Julie suggested Frank Feng and I write a companion article from a technical perspective. I found this a slightly daunting but very interesting challenge, and the article we jointly wrote is now online. The article can be read at http://www.ariadne.ac.uk/issue61/stracchino-feng/

Rapid Innovation in Development

As a new recruit to the Digital library Team particularly YODL-ING, I have had the pleasant opportunity to attend the JISC conference – Rapid innovation in Technology – hosted at the breath taking City of Manchester Stadium by UKOLN.

The two day conference was organised into a series of events focused around introducing and encouraging the exchange of ideas between developers from the recently funded JISC Rapid Innovation Projects.  The first day had a series of short introductory speeches from each participant, followed by a series of expert talks and review groups.  The second day saw the official launch of DevCSI – a community project to establish a network for developers in education sector, as well as expert talks and presentations from developers.

Each invited guest was required to give a 45 second presentation on their projects followed by constructive feedback and then a 20 second condensed “Dragon’s Den” like pitch the following day.  Being on the job for two days, I didn’t expect the third day would involve presenting to room of 50 people about the project! The baptism of fire approach however did help condense my ideas about the project into a succinct pitch, a useful skill indeed. A short interview of the YODL-ING project was taken by blogger Kirsty McGill and presented at the IEDemonstrator blog, with videos of the 20 second pitch to follow.

Overall the conference was well organised, enjoyable and productive.

Till the next one! Nigel.

YODL upgrade and downtime 14th to 18th september

We are continuing to develop “behind the scenes” stuff on YODL, and as a result of this will be making some system changes next week. This will mean that YODL will not be available all week (14th to 18th Sept 2009) but will make our system a bit more flexible in the long run, and take us closer to the point at which we can roll out YODL from the beta testing stage to making it available to the university as a whole

YODL-ING at York, quietly

We’ve been a little quiet in York’s latest venture into the JISC realm, but things are really starting to move forward now.

The project, York Digital Library – Integration for the Next Generation’ (YODL-ING), will implement and develop a number of  technologies to enhance and embed repositories into the information infrastructure of the University of York. We’ve already kicked off work with the Fedora gurus at Acuity Unlimited on some work around supporting metadata creation and searching with ontologies, and also on access control and policy managment, particularly around storing licence information and visualising licence terms to users, building on Acuity’s work on the RELI project.  In addition we’re working with colleagues from the White Rose Research Online (WRRO), our EPrints repository which we share with Leeds and Sheffield Universities,and from Leeds’ LUDOS repository to look at building a SWORD client for offering one-stop deposit. Other work will look at integrating our multimedia digital library into York’s VLE, Streaming Service and the forthcoming Library discovery tool, in order to offer new interfaces for interacting with digital library content.  Thinks are already ramping up, but will be even busier when our new developer starts in September.  Look out for access control use cases and requirements, and a SWORD client specification in the next couple of months.

All of this ties into work on YODL, which is still marching forward.  In particular, and very much related to the work mentioned above, we are almost there with integrating fedora and muradora with our LDAP and student data system, which will allow us to control access based on student credentials and course membership. By the start of the next academic year, we will have a service available for our History of Art students to access image course collections online – a critical milestone for the project.

York-Leeds Exchange of Experience

Notes from an exchange of experience meeting, hosted by the University of York Library and Archives, 24 April 2009, involving York University, Leeds University and York Saint John University.

Present: Jonathan Ainsworth (Leeds), Julie Allinson (York), Michael Emly (Leeds), Frank Feng (York), Matthew Herring (York), Rachel Proudfoot (WRRO), Lauren Shipley (York Saint John), Peri Stracchino (York).

YODL (York Digital Library) – Peri Stracchino

Peri demonstrated YODL, including search and browse functions, resource displays and resource submission workflow. YODL runs on Fedora software, which is extremely flexible and powerful, but only comes with a very basic user interface. YODL is currently using Muradora as its interface software. This was developed especially as a ‘front end’ to Fedora, and has been a useful way of getting a user interface implemented in the short-term.

YODL is now in a semi-live beta testing phase, with 3750 images in it (mostly from the History of Art Department). The team has built a tool (based on Xforms) to create and submit VRA Core 4 image metadata, with auto-suggest functionality or drop-down menus for most fields. LCSH and Getty vocabularies are used. Before the system can go fully live, sufficient access control mechanisms need to be built to satisfy the terms of the CLA license (under which much of the material is created), which is a major challenge. The team has recently carried out the first phase of user testing with academics from the History of Art Department.

York Saint John – Lauren Shipley

YSJ has a one-year-old program to create an open access multimedia repository to store material created as part of university projects and to support teaching. Lauren is the only member of staff working on the project and she works one day a week on it. The first one-year phase was funded by JISC and has focussed on multimedia content, especially from a project called C4C (‘Collaborating for Creativity’). The next phase will be to include etheses and research publications.

The project is live and uses ArchivalWare software. Lauren demonstrated both the public interface (including video clips of student performances) and the metadata creation workflow of ArchivalWare (using Dublin Core). The lack of time dedicated to the project is a barrier (especially as Lauren does not have time to create and ingest metadata records herself and relies on content contributors to do this) and much of her time is spent doing advocacy work for the project. Nevertheless a lot has been achieved for such a project.

LUDOS (Leeds University) – Jonathan Ainsworth

New developments:

• Thousands of digital images and metadata from the library’s special collections added. Some material is restricted as it is in copyright (it was originally created under fair dealing for individual academics and can now only be viewed and managed by LUDOS staff).
• Handle system implemented to create unique permanent IDs for objects, which can be resolved with a global resolution service.
• EAD finding aids added to LUDOS for archival collections
• Forms for user self-submission introduced

Jonathan also demonstrated some features of Digitool, including how objects can appear in more than one collection, based on search terms added to the metadata.

WRRO – Rachel Proudfoot

• Survey of researchers reported than awareness of open access is low and that the idea of institutional repositories is not a meaningful one within academic departments. Researchers do not understand the challenge of cultural changes.
• Advocacy – address awareness with PhD and early career researchers.
• REF is relevant – there is an increasing interest in citation impact (though the evidence is mixed regarding the impact of open access).
• Workflow – capturing the correct version of a paper is an issue. The optimum is at the point of publication, but also good to capture early ‘from the desktop’.
• Symplectic software used to harvest metadata about Leeds publications from abstracting and indexing services – this can later be matched up with papers deposited to WRRO earlier in their publication processes.
• How to capture grant data – Symplectic?
• Promoting self-archiving (this is more scalable than having dedicated staff to do ingesting/metadata creation). This is a big challenge, however. Centralised copyright checking will continue (some academics are worried about breaking copyright; others are not concerned enough).
• Investigating ways of importing metadata from various sources (e.g. from departmental and personal websites), but this is of variable quality. However, it is better than having no metadata.
• Access control – this is difficult as the three institutions (Leeds, York, Sheffield) all use different systems.
• Etheses – new project to add these to WRRO.

SWORD – Julie Allinson

SWORD is a standard for submitting content to repositories, which itself uses the Atom publishing protocol with an extension for metadata. The basic concept is to allow content creators to submit content to repositories easily and potentially to more than one repository with a single operation. There are both web and desktop clients for doing this. Both are based on the concept of a transaction with the client requesting a service document from the repository and receiving a receipt after their submission.

Discussion

Topics discussed included:
• Metadata – the problems of describing complex resources, such as the Michael Nyman archive acquired by Leeds, using standards such as Dublin Core. YODL’s use of VRA and the flexibility of open source software, such as Fedora, to build bespoke metadata creation workflows provides one solution, but with the downside of development costs.
• Advocacy – achieving institution-wide awareness is very difficult, but crucial to success. Need to work to build basic awareness as widely as possible and to collaborate closely with particular individuals who have content to contribute.

First user testing of YODL

On Tuesday of this (21st April) week we carried out our first user-testing on the Digital Library (YODL), with two academic members of staff from the History of Art Department. We used a method known as ‘thinking aloud’, which involves giving the testers some tasks to complete using the interface you are testing, and asking them to speak out any thoughts, impressions, frustrations they have as they use the system, which you note down. This worked very well and we had a lively session, with plenty of opinions and ideas!

The main outputs were a series of changes to the interface design, some of which are relatively minor and others of which would involve a fair amount of work. In general, the challenge is to create something which meets the specific needs of particular user groups (in this case History of Art), but which is also applicable to the wider user community. We plan to implement some of the changes suggested and then do further testing with History of Art.
