Accessibility 2.0: people, policies and processes

The work of the Web Accessibility Initiative (WAI) is described in a set of technical guidelines designed to maximise accessibility to digital resources. Further activities continue to focus on technical developments, with current discussions exploring the potential merits of use of Semantic Web and Web 2.0 approaches.In this paper we argue that the focus on technologies can be counter-productive. Rather than seeking to enhance accessibility through technical innovations, the authors argue that the priority should be for a user-focussed approach, which embeds best practices through the development of achievable policies and processes and which includes all stakeholders in the process of maximising accessibility.The paper reviews previous work in this area and summarises criticisms of WAI’s approach. The paper further develops a tangram model which describes a pluralistic, as opposed to a universal, approach to Web accessibility, which encourages creativity and diversity in developing accessible services. Such diversity will need to reflect the context of usage, including the aims of a service (informational, educational, cultural, etc.), the users’ and the services providers’ environment.The paper describes a stakeholder approach to embedding best practices, which recognises that organisations will encounter difficulties in developing sustainable approaches by addressing only the needs of the end user and the Web developer. The paper describes work which has informed the ideas in this paper and plans for further work, including an approach to advocacy and education which coins the “Accessibility 2.0” term to describe a renewed approach to accessibility, which builds on previous work but prioritises the importance of the user. The paper concludes by describing the implications of the ideas described in this paper for WAI and for accessibility practitioner stakeholders

The selection, appraisal and retention of digital scientific data: dighlights of an ERPANET/CODATA workshop

CODATA and ERPANET collaborated to convene an international archiving workshop on the selection, appraisal, and retention of digital scientific data, which was held on 15-17 December 2003 at the Biblioteca Nacional in Lisbon, Portugal. The workshop brought together more than 65 researchers, data and information managers, archivists, and librarians from 13 countries to discuss the issues involved in making critical decisions regarding the long-term preservation of the scientific record. One of the major aims for this workshop was to provide an international forum to exchange information about data archiving policies and practices across different scientific, institutional, and national contexts. Highlights from the workshop discussions are presented

Interoperability and FAIRness through a novel combination of Web technologies

Data in the life sciences are extremely diverse and are stored in a broad spectrum of repositories ranging from those designed for particular data types (such as KEGG for pathway data or UniProt for protein data) to those that are general-purpose (such as FigShare, Zenodo, Dataverse or EUDAT). These data have widely different levels of sensitivity and security considerations. For example, clinical observations about genetic mutations in patients are highly sensitive, while observations of species diversity are generally not. The lack of uniformity in data models from one repository to another, and in the richness and availability of metadata descriptions, makes integration and analysis of these data a manual, time-consuming task with no scalability. Here we explore a set of resource-oriented Web design patterns for data discovery, accessibility, transformation, and integration that can be implemented by any general- or special-purpose repository as a means to assist users in finding and reusing their data holdings. We show that by using off-the-shelf technologies, interoperability can be achieved atthe level of an individual spreadsheet cell. We note that the behaviours of this architecture compare favourably to the desiderata defined by the FAIR Data Principles, and can therefore represent an exemplar implementation of those principles. The proposed interoperability design patterns may be used to improve discovery and integration of both new and legacy data, maximizing the utility of all scholarly outputs

Increased Content Accessibility For Wikis And Blogs

This paper aims to introduce a useful approach on the combined use of template based publishing tools (i.e. for blogs and wikis) and content personalization services. The approach considers that the original developers of web content have limited awareness on accessibility issues, and they are facilitated and guided by the editing interface. The publishing mechanism is responsible for storing web content in a flexible representation, where structured content is separated from the formatting information. Intermediate brokering services (i.e aggregators, mediators or simply the portal software) produce multiple versions of the same content in order to increase content accessibility. Finally, end-users are able to set their preferences on how the content will be presented and get a homogeneous representation of the community content. The different versions may comprise multiple languages, audio and text representations etc and be based on a single version of the original content. The structured nature of content produced by template based tools allows intermediate services to intervene and reproduce the original content in various formats and client tools to filter and present information according to user needs and capabilities. The paper presents the focal points of the suggested approach, details on the underlying architecture and presents the required supporting infrastructure

Using accessible digital resources for teaching database design: towards an inclusive distance learning proposal

[Proceedings of] 13th Annual Conference on Innovation and Technology in Computer Science Education (ITiCSE'08), Madrid, Spain, June 30-July 2, 2008This paper introduces a pilot experience in teaching database using accessible digital resources in 3er course of Computer Science degree at Universidad Carlos III de Madrid. A platform containing learning material in different formats (video, audio, slides presentation) has been designed allowing students accessing resources as well as to be evaluated by means of tests. Preliminary results show that 46.81% of the students have already interacted with the system and 97.12% of the students passed the tests.Publicad

A framework for filtering web accessibility guidelines

This paper first presents a framework for filtering the Web Accessibility Guidelines according to contexts of use. It then presents a prototype that implements the framework and explains an evaluation of the prototype

Guidance on how Learning at Scale can be made more accessible

While learning at scale has the potential to widen access to education, the accessibility of courses offered on Massive Open Online Course (MOOC) platforms has not been researched in depth. This paper begins to fill that gap. Data was gathered using the participatory ‘Evidence Café’ method. Thematic analysis identified characteristics of accessible courses on these platforms. These characteristics include elements of both technology and pedagogy. Capturing and analysing expert insights enables this paper to provide guidance on how online courses can be made more accessible. The findings suggest that course production teams need to work collaboratively with providers to address issues of accessibility and involve learners in design, testing and evaluation. Well-designed tutor-supported activities that follow web accessibility and usability guidelines are needed, as well as educator training on accessibility
