W3C publishes a report from the Second Web and TV Workshop, which took place in Berlin in February. The report summarizes the discussion among the 77 participating organizations and highlights some key Web and TV convergence priorities:
Adaptive streaming over HTTP
Home networking and second-screen scenarios
The role of metadata and relation to Semantic Web technology
Ensuring that convergent solutions are accessible
Profiling and testing
Possible extensions to HTML5 for Television
Prioritization now continues in the W3C Web and TV Interest Group. That group will review existing work, as well as the relationship between services on the Web and TV services. It will identify requirements and potential solutions to ensure that the Web will function well with TV.
The W3C Workshop in Berlin was made possible in part by sponsorship from Netflix, IPTV Forum Japan, and Tomo-Digi. This second Web and TV workshop was also organized with the support of the OMWeb EU project. Read the press release about the report.

SEO-Google search filters
To search specific results on google
intitle: / allintitle: Start your query with this tag and follow with your keywords to see who is using good SEO by targeting these keywords in their title tag. Using only “intitle” will show pages with title tags containing any of the keywords you search for, and “allintitle” will only show pages with title tags containing all the keywords. Doing your search with this tool will help you determine who is tightly targeting your keywords by using them in the title tag.
inanchor: / allinanchor:” When trying to find what backlinks any particular page has, there are several options. Google itself will not display every backlink, but using this tag can help you determine who is using the searched keyword in their anchor text for backlinks. This can be used to find both your own site’s anchor text use and how your competition is doing with anchor text.
intext: / allintext:” If you’re trying to determine which pages are using your searched keywords most effectively in the page content, this is your tag. Results here will display which pages are using the target keywords most in their visible content.
link: This is another tag you can use when doing backlink research. When you use this tag with a domain or a full page URL you can see what pages Google has listed that are linking to this page. Again, Google will not list all backlinks, but this can give you a quick rundown of backlinks to specific pages.
site: This is a tag that is often missed for its true value. When you use this tag and follow it with a domain name, it will display all pages that Google’s robots have crawled. If, in addition to this, you add keywords – it will display only pages inside that domain that match the keyword query. This is an easy way to determine if Google has cached a specific page, or for finding out relevant information within a particular domain. You can even do a partial search with this tag to find out all sites of a certain class that match your query. For example, typing “site:.edu” will list all relevant results that only have domains with the “.edu” extension.

XQuery and XPath Full Text 1.0; XQuery Update Facility 1.0 are W3C Recommendations
W3C published two Recommendations : XQuery Update Facility 1.0 and XQuery and XPath Full Text 1.0. The former defines an update facility that extends the XML Query language, XQuery. The XQuery Update Facility provides expressions that can be used to make persistent changes to instances of the XQuery 1.0 and XPath 2.0 Data Model. The latter extends XQuery 1.0 and XPath 2.0 with full-text search capabilities. The former document was published by the XML Query Working Group, the latter jointly with the XSL Working Group.

Google analytics - formula for finding the bounce rate
Bounce rate is a very important metric for website/blog owners. It basically tells you what percentage of your visitors are “bouncing” away after landing on your site (e.g., they just visit one page and leave before clicking on to a second page inside your site). A bounce can occur for several reasons, including:
The visitor hit the “Back” button on his browser.
The visitor closed his browser.
The visitor clicked on one of your ads.
The visitor clicked on one of your external links.
The visitor used the search box on his browser.
The visitor typed a new URL on his browser.
All the actions above would cause the visitor to leave your site. Provided he did any of these actions right after arriving at your site (and before clicking on to a second page), it would be counted as a bounce. In fact the formula for finding the bounce rate on your website is:
Bounce rate = Visits that left after one page / Total number of visits
For example, if during a certain month your site received 120,000 visits, out of which 80,000 bounced after visiting just one page, your bounce rate for that month would be 80,000 divided by 120,000, which equals to 0.66 (or 66%). Notice that you can calculate the bounce rate of your whole website or of single pages inside it.
Obviously the lower the bounce rate on your website, the better, because it means that visitors are getting engaged by your content and design, and that they are clicking to visit a second (third and so on) page on your site.
How do you know the exact bounce rate on your site? A web analytics program like Google Analytics will automatically track the numbers for you.

Web Tracking and Privacy Focus of W3C Workshop
Tracking (e.g., for behavioral advertising) has come to the forefront recently as part of the overall Web privacy conversation in the broader Web and policy community. Several software vendors (including Microsoft, Mozilla, and Google) are offering measures that are intended to permit users to opt out of this tracking, or to prevent tracking by Web sites that are known to engage in these practices. Similar technology is deployed in a number of plugins (including NoScript, AdBlock plus, TACO, and PrivacyChoice). As part of ongoing efforts in the area of user privacy on the Web, W3C is organizing a Workshop on Web Tracking and User Privacy, 28-29 April 2011 in Princeton, New Jersey (USA). Topics are likely to include: whether a do not track proposal is advisable or other means might accomplish the same goals; benefits and challenges of browser-bade approaches; other approaches to better user privacy in the face of frequent online tracking. Anyone may participate in this Workshop; a position paper is required and space is limited.

SEO - Build back links to your website
Article marketing is one of the most effective ways to build back links to your website. It is better to use a couple of high traffic article directories than to submit your articles to hundreds or even thousands of directories as this will create an enormous amount of duplicate content which is devalued by the search engine algorithms. It is also a mistake to put articles on your website that you have used for article marketing purposes because this would create duplicate content on your website. While you certainly want the benefit of back links to increase your search engine results page (SERP) rank you need to take into account other factors which can affect your SERP position such as duplicate content.
Blogging, forum posting and paid advertising on relevant websites can also provide excellent one way links to your website. You can write blog articles on your own blog as well as writing comments and articles on other people's blogs that link back to your website. Forums will generally not allow you to directly link to your website in the posting itself, however you can use a link to your site as a signature under your post which can be just as effective as an embedded back link. Placing paid ads on high traffic, related and authoritative sites can also provide one way links back to your website which is likely to both increase the number of visitors as well as your SERP position.
