The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web. It is particularly intended for representing metadata about Web resources, such as the title, author, and modification date of a Web page, copyright and licensing information about a Web document, or the availability schedule for some shared resource.

RDF is intended for situations in which this information needs to be processed by applications, rather than being only displayed to people. RDF provides a common framework for expressing this information so it can be exchanged between applications without loss of meaning. Since it is a common framework, application designers can leverage the availability of common RDF parsers and processing tools. The ability to exchange information between different applications means that the information may be made available to applications other than those for which it was originally created.

In his report, Band says that rapid adoption of Web 2.0 technologies is not just a critical factor, but a generational one as well, noting that "22 percent of adults now read blogs at least monthly, and 19 percent are members of a social networking site like Facebook or LinkedIn. Even more amazingly, almost one-third of all youth publish a blog at least weekly, and 41 percent of youth visit a social networking site daily."Band also suggests that the true 2.0 shift has been about control and power. "'Web 2.0' began as a user-focused revolution," he writes, "remaking the consumer Web into a landscape that is easy to use, efficient to navigate, populated by self-generated content (versus institutional publications) and driven by ad hoc and established communities of people with similar interests. In a Web 2.0 world, power moves from institutions to consumers because they can now rapidly connect and digitally converse among themselves about the products and services they buy."

In the future, ID providers will loosen their connection to social applications and start taking over management of users' social attributes. Users will be able to log in to applications using credentials hosted by their ID providers of choice and grant permissions to these applications to read or even sync selected fragments of their profile data. The borders of these walled gardens will thus blur, and the social Web will become more of a weave than a patchwork quilt.

Enterprise 2.0 To Become a $4.6 Billion Industry By 2013

For vendors specifically, there are 3 main challenges to becoming successful in this new industry, including: I.T. shops being wary of what they perceive as "consumer-grade" technology Ad-supported web tools generally have "free" as the starting point Web 2.0 tools will have to now compete in a space currently dominated by legacy enterprise software investments

One of the main challenges of getting Web 2.0 into the enterprise will be getting past the gatekeepers of traditional I.T. Businesses have been showing interest in these new technologies, but, ironically, the interest comes from departments outside of I.T. Instead, it's the marketing department, R&D, and corporate communications pushing for the adoption of more Web 2.0-like tools.

-- Improved Community Insight -- Awareness administrators now have increased self-service capability to report and graph participation and success metrics in their communities, including user activity, content activity and more.

offering great new social networking capabilities, advanced reporting and community management that will really help encourage robust community participation

"Over the last year, the Enterprise 2.0 space has gathered significant momentum. We've been working with leading companies to realize the business potential of social media and the benefits of using Web 2.0 communities to stimulate conversations between employees, customers and partners around their brands," said John Bruce, CEO of Awareness. "Our Awareness Summer 2008 release builds on this and lets customers offer their community members a wider variety of engagement points across the Web and a user experience that really encourages participation."

(c) Moreover, a feed could have meta-data about the person doing the rating, listing facts like education level, age, ethnicity, political views, or whatever a person might feel is relevant.

(4) Search engines then use the data aggregated by the registrar(s). Due to the quantity and variety of data published in the aggregated feeds, it becomes possible to weight and filter search results not just on Google-style pagerank algorithms, but also things like: (a) quality according to generally trusted sources; or quality according to your peer group; or quality according to academic and academic-endorsed sources; etc.

Moreover, with data included in the feed about the rater, we would be enabled to see, for any given search, what the top rated websites were for our peer group. How teenage girls rate a news article might differ greatly from how 40-year-old men rate them — and this would be useful data for both groups to have.

McAfee first explains why past knowledge management "solutions" rarely solved anything. He then explains what makes Web 2.0 technologies different. "The good news," he writes, is that the new technologies "focus not on capturing knowledge itself, but rather on the practices and output of knowledge workers." By providing both a platform for collaboration and a means of recording the details of the collaboration, the technologies create a public record of previously private knowledge-sharing conversations, a record that's permanent and easily searched. Knowledge is captured, in other words, as it's created, without requiring any additional work. As people search and use that knowledge, moreover, they refine it - through commenting, linking, syndicating and tagging, for instance - which makes it even more valuable.
