The complexity of web content and the popularity of ubiquitous internet devices complicate the web accessibility and intelligibility, making simple web surfing a complicated task. The problem is even more acute in the case of the disabled persons. This is why the problem of using compact and simple web content is very actual now.
The dynamic development of Internet appliances and the necessity of managing multiple devices complicate even further the problem of web accessibility making it even more urgent. The modern solutions for these
CC/PP stands for Composite Capabilities/Preferences Profile, and is a system for expressing device capabilities and user preferences. With CC/PP, a user with a specific preference, or disability-related need can clarify that even though their browser handles millions of colours, they personally can only distinguish certain colours. Or, perhaps the user navigates exclusively with a keyboard or stylus.
Why do we need CC/PP?
With the growing popularity of ubiquitous Web devices spread across such a broad range of media and bandwidth, authoring for the
When expressing device capabilities, the strength of CC/PP is that it has the flexibility HTTP content negotiation lacks. Far from simply defining a fixed set of preferences that would be used to build
device profiles, the RDF-based framework also allows the creation of whole vocabularies, making the expression of device and agent capability, as well as user preference, infinitely extensible.
Using CC/PP, creators of Web devices and user agents can easily define precise profiles for their products. Web servers and proxies can use these profiles to
A PICS overview that was presented in Europe during the week of March 25, 1996 is available now.
An overview of the PICS system is available from the paper "PICS: Internet Access Controls Without Censorship," which has been submitted for publication. In addition, the on-line presentations Overview of the PICS effort (presented by Albert Vezza, Associate Director, MIT's Lab for Computer Science and Spokesman for PICS, at Internet World, October 30, 1995) and Description of PICS Technical effort (presented by Jim Miller (Research Scientist, World Wide
PICS is a cross-industry working group whose goal is to facilitate the development of technologies to give users of interactive media, such as the Internet, control over the kinds of material to which they and their children have access. PICS members believe that individuals, groups and businesses should have easy access to the widest possible range of content selection products, and a diversity of voluntary rating systems.
In order to advance its goals, PICS will devise a set of standards that facilitate the following:
