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.

New 3-D wiring technique brings scalable quantum computers closer to reality
19.10.2016 | University of Waterloo
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
