From XOWA: the free, open-source, offline wiki application

mwad is a python script / executable by Mattze96 to generate XML dumps using the MediaWiki API

## Overview: XML Dumps

XOWA is an offline wiki application for online wikis. It works by converting a MediaWiki XML dump into an .xowa sqlite3 database.

XML dumps can be obtained in the following locations:

- Wikimedia wikis: https://dumps.wikimedia.org/backup-index.html
- Wikia wikis: On the Special:Statistics for a given wiki. For example, for the freespeech wikia wiki, one can go to http://freespeech.wikia.com/wiki/Special:Statistics
- Other wikis: Varies and depends on wiki setup.

For non-Wikimedia wikis (Wikia wikis and other wikis), the dumps may not be available or out-of-date. For example, the freespech wikia has a dump date of 2013-12-26, which is over 2 and a half years old.

For Wikia wikis, one can request an XML dump by doing the following:

- Logging in with a user account
- Requesting a dump through the Special:Statistics page
- Waiting for the dump to be generated

Other wikis may require emails to the wiki's admins.

An alternative to this process is to use Mattze96's mwad: the Media Wiki Api dump

## Usage

Currently mwad is available as a command-line executable and a python script.

- For up-to-date info, see https://github.com/Mattze96/mwad
- For info as of 2016-07-10, see mwad usage notes below
- For a walk-through synopsis, see the following:

### Generating the dump

#### Executable

- Open up a command prompt

  `cmd`

- Change to the mwad directory

  `cd C:\xowa\bin\windows\python\mwad`

- Run mwad with the following options

  mediawiki_api_dump.win32.exe http://freespeech.wikia.com

#### Python script

- Make sure you have Python 3 installed on your system
- Open up a command prompt

  `cmd`

- Change to the mwad directory

  `cd C:\xowa\bin\any\python\mwad`

- Run mwad with the following options

  python mediawiki_api_dump.py http://freespeech.wikia.com

Both cases will generate an xml file called `freespeech.wikia.com-20160710-pages-articles.xml`

### Importing the dump

- Create a folder called C:\xowa\wiki\freespeech.wikia.com
- Move the xml file to C:\xowa\wiki\freespeech.wikia.com
- Rename the file to freespeech.wikia.com.xml
- Choose "Main Menu" -> "Tools" -> "Import Offline"
- Change "Wiki" to "Other wiki"
- Change "Where to get the dump" to "read from file"
- Select the XML file by clicking "..."
- Press "Import Now"

Depending on the wiki, the Main_Page may not be available. You can use the XOWA search bar to look for pages in the wiki.

## Other notes

- Do not run this on Wikimedia wikis. Wikimedia has strict web-crawling policies. If you run this on a Wikimedia wiki, such as en.wikipedia.org, your IP address will probably be banned and you will be unable to access Wikipedia.
- Pay attention to the licenses for the wiki. All Wikia wikis are under a Creative Commons license for article text[1]. Other wikis may follow similiarly permissive licensing but it is your responsibility to check. If a wiki has a strict copyright license, please do not run mwad on it.
- Web-scraping policies may get your IP banned. Different wikis may have different limits on number of articles downloaded, even through their API. If you're downloading a large wiki, you should consult first with the wiki's admins. Otherwise, your IP address may be flagged as an unauthorized web-crawler and you will be banned.
