Lesson Thirty-Five. HTML 5 – Semantic Web
1.1. HTML5 is a markup language for structuring and presenting content for the World Wide Web and a core technology of the Internet. It is the fifth revision of the HTML standard (created in 1990 and standardized as HTML 4 as of 1997) and, as of December 2012, is a W3C Candidate Recommendation. Its core aims have been to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices (web browsers, parsers, etc.).
Answer the question:
1. What’s the core of HTML5?
Check answers:
1. to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices (web browsers, parsers, etc.).
Interview. Sundar Pichai, Google's head of Chrome and Android, has given his first major interview BY STEVEN LEVY http://www.wired.com/business/2013/05/exclusive-sundar-pichai-reveals-his-plans-for-android/
As head of Chrome you have promoted the vision of cloud-based apps, based on technologies like HTML 5, saying that they will be as powerful and fast as native apps written to run directly on specific machines. But last year Mark Zuckerberg said that Facebook’s biggest mistake was trying to use HTML 5 and the open web for its mobile apps. He said it simply didn’t have the quality and speed to serve his users. Was that a blow to your vision of Chrome?
I think the reality is a bit different. I managed Chrome and apps even before Android. Some of our large applications are now written directly to the device — for instance, we have native Gmail apps. But I disagree with the opinion that all of Facebook’s mobile issues can be blamed on HTML 5. I just don’t think that was true. There are other companies with very successful apps that have taken an HTML 5 approach on mobile and done really well. For instance, a lot of magazines have switched from native back to HTML 5 for the mobile apps. Financial Times did it, and they’ve blogged that their user engagement and traction has increased significantly. It’s the reverse of what Facebook said. And this is the beauty. Each developer’s needs are unique.
Answer the questions:
1. What was the Facebook’s biggest mistake in Mark Zuckerberg’s opinion?
2. What does Sundar Pichai disagree with?
3. What markup language have a lot of magazines starded to use again?
Check answers:
1. Trying to use HTML 5 and the open web for its mobile apps;
2. He disagees with the opinion that all of Facebook’s mobile issues can be blamed on HTML 5.
3. HTML5.
25.2. The Semantic Web is a collaborative movement led by the international standards body, the World Wide Web Consortium (W3C). The standard promotes common data formats on the World Wide Web. By encouraging the inclusion of semantic content in web pages, the Semantic Web aims at converting the current web dominated by unstructured and semi-structured documents into a "web of data". The Semantic Web stack builds on the W3C's Resource Description Framework (RDF)
According to the W3C, "The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries. The term was coined by Tim Berners-Lee for a web of data that can be processed by machines
Microformats extend HTML syntax to create machine-readable semantic markup about objects including people, organisations, events and products.
The Semantic Web proposes to help computers "read" and use the Web. The big idea is pretty simple -- metadata added to Web pages can make the existing World Wide Web machine readable. This won't bestow artificial intelligence or make computers self-aware, but it will give machines tools to find, exchange and, to a limited extent, interpret information. It's an extension of, not a replacement for, the World Wide Web.
That probably sounds a little abstract, and it is. While some sites are already using Semantic Web concepts, a lot of the necessary tools are still in development. In this article, we'll bring the concepts and tools behind the Semantic Web down to earth by applying them to a galaxy far, far away.
