wordpress.org codebase

Question

Is the codebase that runs wordpress.org publicly available? Specifically, I'm interested in the part that parses the plugins SVN repository to determine the current and past versions of plugins.

I know that I have to look at the tags for each plugin but there are complexities around which tag is marked as the Stable tag in the readme.txt.

You can try out the api.wordpress.org.

Take for example the secret MP6 plugin:

http://api.wordpress.org/plugins/info/1.0/mp6.xml

The current version is given by:

<version type="string">
<![CDATA[ 0.8 ]]>
</version>

and it looks like the previous versions are listed in the compatibility tag:

<compatibility type="array">
<array key="3.4.1">
<array key="1.0.0">
<integer>100</integer>
<integer>1</integer>
<integer>1</integer>
</array>
<array key="1.0.1">
<integer>100</integer>
<integer>1</integer>
<integer>1</integer>
</array>
<array key="1.0.2">
<integer>100</integer>
<integer>3</integer>
<integer>3</integer>
</array>
</array>
<array key="3.4.2">
<array key="1.0.2">
<integer>100</integer>
<integer>1</integer>
<integer>1</integer>
</array>
<array key="1.0.5">
<integer>100</integer>
<integer>1</integer>
<integer>1</integer>
</array>
</array>
<array key="3.5">
<array key="1.0.5">
<integer>100</integer>
<integer>1</integer>
<integer>1</integer>
</array>
</array>
<array key="3.5.1">
<array key="1.0.6">
<integer>100</integer>
<integer>2</integer>
<integer>2</integer>
</array>
</array>
</compatibility>

You can compare it to the SVN versions given here:

http://wordpress.org/extend/plugins/mp6/developers/

You can also get json or serialized php versions:

http://api.wordpress.org/plugins/info/1.0/mp6.json
http://api.wordpress.org/plugins/info/1.0/mp6.php
