Download and extract categorylinks.sql. For example, for Simple Wikipedia, do the following:
<ul>
<li>
Navigate to <a href="http://dumps.wikimedia.org/simplewiki/latest/" rel="nofollow" class="external free">http://dumps.wikimedia.org/simplewiki/latest/</a>
</li>
<li>
Download the file marked simplewiki-latest-categorylinks.sql.gz
</li>
<li>
Unzip simplewiki-latest-categorylinks.sql.gz. When you are done, you will have a file called /xowa/wiki/simple.wikipedia.org/simplewiki-latest-categorylinks.sql
</li>
</ul>
</li>
<li>
Download and extract page_props.sql. For example, for Simple Wikipedia, do the following:
<ul>
<li>
Navigate to <a href="http://dumps.wikimedia.org/simplewiki/latest/" rel="nofollow" class="external free">http://dumps.wikimedia.org/simplewiki/latest/</a>
</li>
<li>
Download the file marked simplewiki-latest-page_props.sql.gz
</li>
<li>
Unzip simplewiki-latest-page_props.sql.gz. When you are done, you will have a file called /xowa/wiki/simple.wikipedia.org/simplewiki-latest-page_props.sql
</li>
</ul>
</li>
<li>
Open up /xowa/xowa_build.gfs and replace the file with the following:
</li>
</ul>
<pre>
app.bldr.pause_at_end_('n');
app.bldr.cmds {
add ('simple.wikipedia.org' , 'text.cat.core');
add ('simple.wikipedia.org' , 'text.cat.link');
add ('simple.wikipedia.org' , 'text.cat.hidden');
}
app.bldr.run;
</pre>
<ul>
<li>
Run <code>java -Xmx512m -jar xowa_linux_64.jar --cmd_file xowa_build.gfs --app_mode cmd</code>
</li>
</ul>
<p>
For Simple Wikipedia, the entire process should take less than 5 minutes. For English Wikipedia, the process will take about 1 hour.

<p>
For reference, this is the current script to set up the V2 Category system
</p>
<pre>
app.bldr.pause_at_end_('n');
app.bldr.cmds
.add_many('simple.wikipedia.org', 'ctg.hiddencat_sql', 'ctg.hiddencat_ttl', 'ctg.link_sql', 'ctg.link_idx').owner
;
app.bldr.run;
</pre>
<p>
Note that 'ctg.link_sql' and 'ctg.link_idx' are required.
</p>
<p>
Note that 'ctg.hiddencat_sql' and 'ctg.hiddencat_ttl' can be omitted. However, it is recommended that they be run (for English Wikipedia, it adds less than 5 minutes to the entire process).
</p>
<h3>
<span class="mw-headline" id="ctg.hiddencat_sql">ctg.hiddencat_sql</span>
</h3>
<ul>
<li>
This command will look for a file matching *page_props.sql in the wiki directory
</li>
</ul>
<dl>
<dd>
For example: /xowa/wiki/simple.wikipedia.org/simplewiki-latest-page_props.sql. Note this sql will have a format of (page_id, prop_name, prop_val)
</dd>
</dl>
<ul>
<li>
It will then parse the .sql file and look for entries having a prop_name of "hiddencat". For example (1, 'hiddencat', '')
</li>
</ul>
<ul>
<li>
When it's done, it will generate a Base85 encoded list of all page_ids
</li>
</ul>
<dl>
<dd>
The output directory will be /xowa/wiki/simple.wikipedia.org/tmp/ctg.hiddencat_sql/make/
</dd>
<dd>
An example of a file would be:
</dd>
</dl>
<pre>
!!!!#
!!!!$
</pre>
<h3>
<span class="mw-headline" id="ctg.hiddencat_ttl">ctg.hiddencat_ttl</span>
</h3>
<ul>
<li>
This command will look at the output of ctg.hiddencat_sql and find the appropriate title for the given id
</li>
</ul>
<dl>
<dd>
This step is necessary as the category indexes are sorted by title, not by id.
</dd>
</dl>
<ul>
<li>
When it's done, it will generate a sorted list of title|id.
</li>
</ul>
<dl>
<dd>
The output directory will be /xowa/wiki/simple.wikipedia.org/tmp/ctg.hiddencat_ttl/make/
</dd>

For example: /xowa/wiki/simple.wikipedia.org/simplewiki-latest-categorylinks.sql.

<ul>

It will then parse the .sql file and extract the following data: category_name, page_id, page_member_type, page_sortkey, page_member_add_date
</li>
</ul>
<ul>
<li>
When it's done, it will generate a sorted list of category|type|sortkey|id|date.

This command will generate the /category2/ hive based on the output of the above commands. It uses the following:
<ul>
<li>
Category link data as built in /xowa/wiki/simple.wikipedia.org/tmp/ctg.link_sql/make/.
</li>
<li>
Category hidden data as built in /xowa/wiki/simple.wikipedia.org/tmp/ctg.hiddencat_ttl/make/.
</li>
</ul>
</li>
</ul>
<ul>
<li>
It will then merge the output of the above data and generate the /main/ and /link/ sudirectories in /category2/
</li>
</ul>

<span class="mw-headline" id=".2Fcategory2.2F">/category2/</span>
</h2>
<h3>
<span class="mw-headline" id=".2Fmain.2F">/main/</span>
</h3>
<p>
The main files are located at /xowa/wiki/simple.wikipedia.org/site/category2/main/. They follow the same hive structure as the other directories (a main reg.csv and subdirectories of the format of /00/00/00/00/0123456789.xdat)
</p>
<p>
Each file contains header information for a category. Presently, this includes the following:
</p>
<ul>
<li>
Category name
</li>
<li>
Hidden: "y" means hidden; "n" means not hidden
</li>
<li>
Number of subcategories (Base85 encoded)
</li>
<li>
Number of files (Base85 encoded)
</li>
<li>
Number of pages (Base85 encoded)

EX: <code>A|y|!!!!!|!!!!!|!!!!!|</code>
</dd>
</dl>
<h3>
<span class="mw-headline" id=".2Flink.2F">/link/</span>
</h3>
<p>
The link files are located at /xowa/wiki/simple.wikipedia.org/site/category2/link/. They also follow the same hive structure as the other directories.
</p>
<p>
Each file contains members of a category. Presently, this includes the following:
</p>
<ul>
<li>
Category name
</li>
<li>
Length of subcategories data
</li>
<li>
Length of files data
</li>
<li>
Length of pages data
</li>
<li>
A series of entries listing category members
<ul>
<li>
Note that these entries are broken into subgroups (subcategories / files / pages) depending on the preceding lengths.
</li>
<li>
Each entry is in a semi-colon delimited format
<ul>
<li>
page_id (Base85 encoded)

XOWA currently has two category systems. This page will explain the rationale / details behind both.
</p>
<p>
An overview follows below.
</p>
<p>
For more information about V2 setup see <a href="http://xowa.org/wiki/home/page/App/Category/Building.html" id="xolnki_2" title="App/Category/Building" class="xowa-visited">App/Category/Building</a>
</p>
<p>
For more information about V2 internals see <a href="http://xowa.org/wiki/home/page/App/Category/Internals.html" id="xolnki_3" title="App/Category/Internals">App/Category/Internals</a>
</p>
<h2>
<span class="mw-headline" id="Version_1">Version 1</span>
</h2>
<p>
Version 1 is a simplistic category system.
</p>
<ul>
<li>
It relies only on page content inside the xml file. It does not use any of the category*.sql dumps.
</li>
</ul>
<p>
Note the following limitations:
</p>
<ul>
<li>
Does not work with large categories. It gets linearly worse with more members (do not use it to load a category with over 10,000 members)
</li>
<li>
Does not support paging. If a category has 1,000 members, it will load title information on all 1,000 (instead of just the first 200)
</li>
<li>
Does not use sortkey. For example, Jimmy Wales will alphabetize under J (for Jimmy Wales) instead of W (for Wales, Jimmy)
</li>
<li>
Does not accurately reflect page membership in categories.
</li>
</ul>
<dl>
<dd>
For example, most hidden categories are added to a template which is then included in a page.
</dd>
<dd>
Specifically, a page called "File:GNU.png" may belong to "All free media". However, the "File:GNU.png" page doesn't have the [[Category:All_free_media]] but instead embeds a template {{All_non_free_media}} which has the [[Category:All_free_media]]

Since a full parse (with templates) of the entire xml file would take many hours, this membership data is omitted.

V1 should be considered obsolete. No signficant changes will be made to it, as V2 is the official category system.
</p>
<p>
However, because V1 is faster to setup than V2, it still remains the default (with a strong recommendation to upgrade to V2 when time permits)

<span class="mw-headline" id="Version_2">Version 2</span>
</h2>
<p>
Version 2 is an accurate category system.
</p>
<ul>
<li>
It uses the Wikimedia dump files: categorylinks.sql, page_props.sql
</li>
</ul>
<p>
It addresses each of the limitations of version 1, including
</p>
<ul>
<li>
Works with large categories
</li>
<li>
Supports paging
</li>
<li>
Uses sortkey
</li>
<li>
Accurately includes all members of a category
</li>
</ul>
<p>
It has a few limitations:
</p>
<ul>
<li>
It requires additional dump files (as mentioned above).
</li>
<li>
It takes longer to setup. A separate .sql file must be parsed. For English Wikipedia this process takes about another hour.
</li>
<li>
It takes more disk space. The v2 system stores sortkeys individually per entry (just like Wikipedia). However this text data greatly increases the overall file size. English Wikipedia will have about 10.0 GB of extra data.
</li>
</ul>
<p>
V2 is the official category system and should generate Category pages just like Wikipedia.
