With my move from the University of Dundee's School of Computing, I thought it time I ported the old CCF website to the OATS portal. With the Bliss Think Tank in July'07 we've been busy hacking more demonstrators. Mats, Bengt and Lars have been busy fine-tuning the SYMBERED system (CCF support for CMS - using PHP, MySQL, Java). I've been busy working on a .NET infrastructure and building a central CCF ontology in SQLServer. The database I've been working with is now populated with around 9000 concepts (based on the STANDUP project ontology) and around 3000 Bliss symbols (some of which are mapped to concept codes). There is an prototype asp.net website where you can search the ontologies, update the bliss-ccf mappings, write ruby annotated bliss messages (then you can copy the source to your own website like i've done below). This webservice could be used as a portal to manage the ccf, and more excitingly, for use by other sofware / web applications, e.g. FoxySymbols. I hope to get the webservice & database hosted soon.

Background

Around the world, people with impaired communication, including difficulties to read or write, may use symbols as an alternative or complement to character based texts. Referencing to, and exchanging these alternatively coded messages over the Internet is difficult due to the lack of standardised encoding schemes and common practises. This site is intended to motivate, describe and promote the introduction and adoption of a common, open and vendor neutral Concept Coding Framework (CCF) to overcome some of these difficulties. In particular will act as a base for all contribution to this work - be it formal documentation or informal discussions.

The suggested CCF has been carefully designed to be conformant to the standard language technologies that are rapidly developing and penetrating the Internet communities. In this way we believe that the proposed CCF can contribute to a major leap in bridging between different technologies and products developed for AAC users and, more importantly, between these Assistive Technologies (AT) and the main-stream technologies of today's and tomorrow's networked information society.

The bridging approach also implies that the CCF is not intended to replace and exclude the use and development of current and future proprietary assistive technologies in the AAC field. Instead the CCF and its bridging technology and tools are designed to provide added value for all stake-holders; AAC users, special product developers and service providers, as well as general service and information providers who want to support improved accessibility to their products.

Designed to be used over the Internet for email, web-based activities, chat and/or other emerging Internet based services, the CCF technology can, however, be used by software manufacturers also to provide additional functionality, enhanced support for, and integration of, software and systems with multi-modal language features mainly intended for local use.

Although, this work is part of the EU funded WWAAC project, the concept coding work is to be kept open source as we want to collaborate with experts and stakeholders in both the AAC field and internet technologies/accessibility area. Thus we are wanting to use this area to establish an interest group in the concept coding approach. if you are interested in getting involved at whatever level then please contact us.
