Hi Everyone, On the RDF IG list lately, there has been a lot of conversation about the Semantic Web. One action item that has been raised is using RDF and meta-data to optimise page accessibility; and hence I am writing to this list. It has been suggested to me (by William Loughborough on the RDF IG list) that: [[[ In the WAI Working Groups for both content guidelines and tools (and possibly protocols/formats) we are wrestling with the notion of suggesting/requiring metadata dealing with the conformance claims made by authors that are a little more reassuring than just a logo at the bottom. ]]] - http://lists.w3.org/Archives/Public/www-rdf-interest/2000Nov/0106.html Therefore, may I suggest the following checkpoints and implementation examples: Checkpoints (where item 1. is A/AA, and item 2. AAA):- 1. Include Dublin Core or similar RDF based meta-statements where not constrained by validation, or provide alternative methods for doing so (e.g. using qualified Dublin Core metadata in HTML META elements). Provide RDF site and page summaries. 2. Using the methods in 1., indicate that the author(s) have followed the guidelines and checked their site in accordance with WAI guidelines. An example of this follows:- In HTML (currently: see [1]): <meta name="DC.title" content="Checkpoint Checker" /> <meta name="DC.description" content="W3C WAI WCAG 1.0 Checkpoint Checker" /> <meta name="description" content="W3C WAI WCAG 1.0 Checkpoint Checker" /> <meta name="W3C WAI WCAG 1.0 Conformance Level" content="AAA - Triple A" /> In RDF: <rdf:RDF xmlns:dc="http://purl.org/DC" xmlns:wcag="http://www.w3.org/2000/wcag" xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" > <rdf:description rdf:about="http://rdf.pair.com/xchecker.htm" dc:title="Checkpoint Checker" dc:description="W3C WAI WCAG 1.0 Checkpoint Checker" wcag:version="1.0" wcag:level="AAA" wcag:proselevel="Triple A" /> </rdf:RDF> The xmlns:wcag namespace is just an example: the WAI would have to create a real and suitable one. [1] Also, could someone ask the HTML WG to provide an RDF Dublin Core module in either m12n or XHTML 2.0? Currently we can only use the profile attribute in head to link to an RDF file. (Mr. Raggett, as HTML activity lead, would it be possible for you take this up?). Looking at the WAI IG charter, this applies to 2.1.1 and 2.1.3 in the following:- [[[ 2. Scope 2.1 Scope of WAI IG discussion The scope of issues for WAI IG consideration includes issues within the five areas of work of the Web Accessibility Initiative: 1. ensuring that the technologies of the Web support accessibility; 2. developing guidelines for Web accessibility; 3. developing tools to facilitate Web accessibility; 4. conducting education and outreach to promote Web accessibility; 5. tracking research and development which can affect future Web accessibility. ]]] - http://www.w3.org/WAI/IG/Charter Kindest Regards, Sean B.
