1. Architectural services – NavigAbile is, first of all, a Service Oriented Architecture (SOA). Architectural services are thus the first product of the project and the “foundations” of NavigAbile, both for current and future applications. Among the core services there are:
• Interoperability services – they are the interface of NavigAbile facing the external world. These services are exposed as web services, to be used by other sites/portals which choose to adopt NavigAbile.
• Profiling – directory service containing all user profiles and related personalization parameters
• Page filtering – the Page Filtering system contains a page generation engine that enhances accessibility and provides content personalization capabilities which go as far as the layout on page. The filter renders the page through a proprietary tag system and an HTML template.
• Communication services - created to facilitate communication, among them we have the multimodal dictionary, able to automatically associate a word or sentence to its related image using different graphic languages and formats (PCS, Bliss, GIFs, etc.), the Communication Table, the Sentences Composer.
• Support services for accessible content creation – they support content producers in the creation of accessible content, with the help of a text readability index and the possibility to verify the presence of a certain word in a pre-determined vocabulary.
2. NavigAbile website (www.navigabile.eu) – the website was created to:
• provide the users with basic accessible web services, such as e-mail, the billboard and the news;
• share educational material, presented using all the architectural services of NavigAbile, among the users and their aides;
3. NavigAbile Network Support Services (NNSS):
• Help desk to support users and operators;
• Tutors (NaviTutor) to closely follow-up NavigAbile communities;
