Hsin-Yu Chiang ScDa & Chien-Hsiou Liu PhDa (2011) Evaluation of the Benefits of Assistive Reading Software: Perceptions of High School Students with Learning Disabilities. Assistive Technology: The Official Journal of RESNA Volume 23, Issue 4, 2011 DOI:10.1080/10400435.2011.614673 pages 199-204 Published online: 04 Nov 2011 http://www.tandfonline.com/doi/full/10.1080/10400435.2011.614673#tabModule I would love a template of what is required as well - so sorry but I have lots of papers but not sure which ones you want as I could help with AAC - do you want the benefits of technology use for this group as a collection of research papers?

Using RDFa, the author can annotate her page to make the structured data clear: For example, one can say that this text is equivalent of a metadata title (a term defined at http://purl.org/dc/terms/title) as follows: <h2 property="http://purl.org/dc/terms/title">The Trouble with Bob</h2> <p>Date: <span property="http://purl.org/dc/terms/created">2011-09-10</span></p> See http://www.w3.org/TR/xhtml-rdfa-primer/diagrams/title-and-author.svg for a pictorial representation of the data. Note thatyou can also define the vocab for the whole page making the attribute values simpler, as follows: <body vocab="http://purl.org/dc/terms/"> ... <h2 property="title">The Trouble with Bob</h2> <p>Date: <span property="created">2011-09-10</span></p> The attributes in RDFa are: • about – a URI specifying the resource the metadata is about • rel and rev – specifying a relationship and reverse-relationship with another resource, respectively • src, href and resource – specifying the partner resource • property – specifying a property for the content of an element or the partner resource • content – optional attribute that overrides the content of the element when using the property attribute • datatype – optional attribute that specifies the datatype of text specified for use with the property attribute • typeof – optional attribute that specifies the RDF type(s) of the subject or the partner resource (the resource that the metadata is about). Looking at the following example <p>My name is <span property="foaf:nick">John D</span> and I like <a href="http://www.neubauten.org/" rel="foaf:interest" xml:lang="de">Einstürzende Neubauten</a>. </p> The RDFa terms are used to say what the element is, and how it is is relivent Any compliant vocablery can be link to to say this is an "X" Hence RDFa enables us to add more information to web pages without standardizing terms in HTML itself, and one can use vocabularies external to the W3C. For example authors could reference use terms defined or explained elsewhere, as symbols or, for example, terms defined by EPub (see http://www.idpf.org/epub/vocab/structure/) However RDFa can also be used t create a vocabularies (or you can use full RDF ). This is important because one can also add values to the ROLE attribute in HTML as HTML Role is modular. See http://www.w3.org/1999/xhtml/vocab Another use of RDFa for COGA would be to identify of alternative content for alternitive access strategies that exist in the same page. Many RDFa vocabularies exist such as http://logd.tw.rpi.edu/datasets_rdfa, and http://schema.org/docs/schema_org_rdfa.html Conclusion Currently RDFa does not seem to be used to improve accessibility for people with cognitive disabilities. No author strategies are defined to this aim. However it can act as an enabling technology for accessibility for people with cognitive disabilities allowing: • alternative content • adaptable content • extra information.
