Today W3C takes steps toward building a Web of trust, and making it possible to discover relevant, quality content more efficiently. When content providers use POWDER, the Protocol for Web Description Resources, they help people with tasks such as seeking sound medical advice, looking for trustworthy retailers, or searching for content available under a particular license (for instance, a Creative Commons license).
"People ask me how to pick out useful content among the vast amounts of information on the Web," said POWDER Working Group Chair Phil Archer of the Institute of Informatics & Telecommunications (IIT), NCSR Demokritos. "POWDER contributes to the solution. POWDER statements combined with authentication technology can help people find information that meets their own standards for quality, automatically."
Kai Scheppe of Deutsche Telekom AG added, "From a content provider's perspective this new means of describing Web resources opens up new possibilities for our customers to discover content with a higher degree of relevance. We are currently in the process of bringing POWDER documents online and look forward to broad spectrum adoption of this technology by information providers, aggregators and users alike."
POWDER Descriptions Help Automate Content Discovery
When content providers use POWDER descriptions, people can use tools to help discover relevant content. For instance, a site wishing to promote the mobile-friendliness of its content or applications can tell the world using POWDER. Content providers start by creating content that is conformant with W3C's mobileOK scheme and validating it with the mobileOK Checker. The checker generates POWDER statements that apply to individual pages. But a key feature of POWDER is that it lets content providers make statements about groups of resources - typically all the pages, images and videos on a Web site. Other tools such as the i-sieve POWDER generator (not from W3C) generates POWDER statements about the mobile-friendliness of entire sites. Once these POWDER statements are in place they can be used by search engines or other tools to help people find mobile-friendly content.
POWDER statements alone do not guarantee quality or relevance, but POWDER statements do promote accountability: they are always attributed to a "publisher." Knowing that people seek to build trust via the Web, publishers can take the next step by ensuring that their POWDER statements can be authenticated automatically. One consequence is that people will no longer have to "click to verify" trustmarks. Instead, tools can automate the verification, making life simpler for users while reducing the likelihood of spoofing.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
