We've heard from a number of site owners who want to make sure their public source code is searchable via Google Code Search. To help with that, we extended the Sitemap Protocol to support code files. This makes it possible to specify all the code files on your site, as well as the programming language and software license for each file.

To get started, check out the new Code Search tags for Sitemaps. For complete software packages that are archives (.tar, .tar.gz, .tar.bz2, or .zip), you can create a packagemap file to describe all the individual code files in each package. For example:

  <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
          xmlns:codesearch="http://www.google.com/codesearch/schemas/sitemap/1.0">
  <url>
     <loc>http://example.com/download/myfile.c</loc>
     <codesearch:codesearch>
         <codesearch:filetype>C</codesearch:filetype>
         <codesearch:license>LGPL</codesearch:license>
     </codesearch:codesearch>
  </url>

  <url>
     <loc>http://example.com/download/myproject.tgz</loc>
     <codesearch:codesearch>
         <codesearch:filetype>archive</codesearch:filetype>
         <codesearch:license>Apache</codesearch:license>
         <codesearch:packagemap>packagemap.xml</codesearch:packagemap>
     </codesearch:codesearch>
  </url>
  </urlset>

Once you've created your Sitemap, post it to a public URL on your site and then be sure to submit it through Google Webmaster Tools.

We hope this effort will help make even more code accessible and useful for developers. Let us know what you think. There's still a lot more code out there, so we'll keep working on improving Google Code Search as a tool for finding it.

Have you ever wanted to submit your various content types (video, images, etc.) in one Sitemap? Now you can! If your site contains videos, images, mobile URLs, code or geo information, you can now create—and submit—a Sitemap with all the information.

Site owners have been leveraging Sitemaps to let Google know about their sites’ content since Sitemaps were first introduced in 2005. Since that time additional specialized Sitemap formats have been introduced to better accommodate video, images, mobile, code or geographic content. With the increasing number of specialized formats, we’d like to make it easier for you by supporting Sitemaps that can include multiple content types in the same file.

The structure of a Sitemap with multiple content types is similar to a standard Sitemap, with the additional ability to contain URLs referencing different content types. Here's an example of a Sitemap that contains a reference to a standard web page for Web search, image content for Image search and a video reference to be included in Video search:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
 xmlns:image="http://www.google.com/schemas/sitemap-image/1.1"
 xmlns:video="http://www.google.com/schemas/sitemap-video/1.1">
<url>
 <loc>http://example.com/foo.html</loc>
 <image:image>
   <image:loc>http://example.com/image.jpg</image:loc>
 </image:image>
 <video:video>
   <video:content_loc>http://example.com/videoABC.flv</video:content_loc>
   <video:title>Grilling tofu for summer</video:title>
 </video:video>
</url>
</urlset>

Here's an example of what you'll see in Webmaster Tools when a Sitemap containing multiple content types is submitted:



We hope the capability to include multiple content types in one Sitemap simplifies your Sitemap submission. The rest of the Sitemap rules, like 50,000 max URLs in one file and the 10MB uncompressed file size limit, still apply.

Last spring, the Sitemaps protocol was expanded to include the autodiscovery of Sitemaps using robots.txt to let us and other search engines supporting the protocol know about your Sitemaps. We subsequently also announced support for Sitemap cross-submissions using Google Webmaster Tools, making it possible to submit Sitemaps for multiple hosts on a single dedicated host. So it was only time before we took the next logical step of marrying the two and allowing Sitemap cross-submissions using robots.txt. And today we're doing just that.

We're making it easier for webmasters to place Sitemaps for multiple hosts on a single host and then letting us know by including the location of these Sitemaps in the appropriate robots.txt.

How would this work? Say for example you want to submit a Sitemap for each of the two hosts you own, www.example.com and host2.google.com. For simplicity's sake, you may want to host the Sitemaps on one of the hosts, www.example.com. For example, if you have a Content Management System (CMS), it might be easier for you to change your robots.txt files than to change content in a directory.

You can now exercise the cross-submission support via robots.txt (by letting us know the location of the Sitemaps):

a) The robots.txt for www.example.com would include:
Sitemap: http://www.example.com/sitemap-www-example.xml

b) And similarly, the robots.txt for host2.google.com would include:
Sitemap: http://www.example.com/sitemap-host2-google.xml

By indicating in each individual host's robots.txt file where that host's Sitemap lives you are in essence proving that you own the host for which you are specifying the Sitemap. And by choosing to host all of the Sitemaps on a single host, it becomes simpler to manage your Sitemaps.

We are making this announcement today on Sitemaps.org as a joint effort.
