Even by the standards of web software, the Google App Engine team moves pretty quickly, with a new version every 6 weeks or so. (I learned how fast they go when I was writing App Engine technical docs and trying to keep up with what the engineers were creating.) This week, the team launched App Engine 1.5.1, with a nice collection of new features, including support in the SDK for testing the High Replication Datastore, an API to use ProtoRPC from Python, and support for user presence in the Channel API. You can see the complete list and more details in the App Engine Blog.

Nature does new releases too, although it usually takes a lot longer to add new features and fix bugs. Can the current version of humans sense a magnetic field? Scientists in Massachusetts found indirect clues by replacing a fly protein with a human one. In a study, the human cryptochrome protein restored the fly’s ability to respond to a magnetic field. Not only is that pretty cool, that BBC Science News page has an awesome picture of a fly.

Finally, if you have a few minutes this weekend, check out this nifty video that takes an original and fun look at multiplication.

Today, we’re happy to introduce Recipe View, a new way of finding recipes when searching on Google. Recipe View enables you to filter your regular web search results to show only recipes and to restrict results based on ingredients, cook time, or calorie preferences:

Read more about Recipe View on the Official Google Blog and be sure to check out our video of Google Chef Scott Giambastiani demonstrating how he uses Recipe View to find great recipes for Googlers:



Recipe View is based on data from recipe rich snippets markup. As a webmaster, to make sure your recipe content can show in Recipe View (currently rolling out in the US and Japan) as well as in regular search results with rich snippets (available globally), be sure to add structured data markup to your recipe pages. Rich snippets are also available for reviews, people, products, and events, and we’ll continue to expand this list of categories over time. You can always see the full list of supported types by referring to our rich snippets documentation and by watching for further updates here on the Webmaster Central Blog.

This marks an exciting milestone for us -- it’s the first time we’ve introduced search filters based on rich snippets markup from webmasters. Over time, we’ll continue exploring new ways to enhance the search experience using this data.

Webmaster level: All

In December 2011 we announced annotations for sites that target users in many languages and, optionally, countries. These annotations define a cluster of equivalent pages that target users around the world, and were implemented using rel-alternate-hreflang link elements in the HTML of each page in the cluster.

Based on webmaster feedback and other considerations, today we’re adding support for specifying the rel-alternate-hreflang annotations in Sitemaps. Using Sitemaps instead of HTML link elements offers many advantages including smaller page size and easier deployment for some websites.

To see how this works, let's take a simple example: We wish to specify that for the URL http://www.example.com/en, targeting English language users, the equivalent URL targeting German language speakers http://www.example.com/de. Up till now, the only way to add such annotation is to use a link element, either as an HTTP header or as HTML elements on both URLs like this:

<link rel="alternate" hreflang="en" href="http://www.example.com/en" >
<link rel="alternate" hreflang="de" href="http://www.example.com/de" >

As of today, you can alternately use the following equivalent markup in Sitemaps:

<url>
<loc>http://www.example.com/en</loc>
<xhtml:link
rel="alternate"
hreflang="de"
href="http://www.example.com/de" />

<xhtml:link
rel="alternate"
hreflang="en"
href="http://www.example.com/en" />

</url>
<url>
<loc>http://www.example.com/de</loc>
<xhtml:link
rel="alternate"
hreflang="de"
href="http://www.example.com/de" />

<xhtml:link
rel="alternate"
hreflang="en"
href="http://www.example.com/en" />

</url>

Briefly, the new Sitemaps tags shown in bold function in the same way as the HTML link tags, with both using the same attributes. The full technical details of how the annotations are implemented in Sitemaps, including how to implement the xhtml namespace for the link tag, are in our new Help Center article.

A more detailed example can be found in our new Help Center article, and if you need more help, please ask in our brand new internationalization help forum.
