ImportTextFiles.php

Please refer to the original MediaWiki document

A Typical Importation Process

1. Extract text content from some sources, ideally Wikipedia or some reputable data source with existing data model.
   1. In the case of Wikipedia, every page can be considered as a single text file, and each page has a unique ID provided in either XML or MediaWiki data model.
   2. Dump all the textual data content into a directory. Each page should be stored in a unique file, whose page name is stored in a comma delimited file (CSV), that each line associates a unique ID with a the page name.
2. Move the file into a place where MediaWiki's maintenance script can easily have access, such as /var/www/html/images. For Docker deployments, this directory is likely to be mapped onto the host machine's hard drive, therefore, easy to put the text files under this directory. For example:INPUTDATA_DIR under /var/www/html/images.
3. Go to the terminal of the host machine that serves MediaWiki, then, run the importTextFiles.php script like follows:

root@hostname:/var/www/html/#php ./maintenance/importTextFiles.php -s "Loading Textual Content from external sources"  --overwrite --use-timestamp ./images/INPUTDATA_DIR/*

Preprocess file names

Give a list of input data files, for example, a list of files from Wikipedia's Module collection, which contains a list of unique IDs mapping to the page name. The following command will produce a smaller file that contains the replacement.

ls ./images/TEMPLATE/ | xargs -n 1 -i grep {} wp_articles_template.csv > template_replacement.txt

When performing data extraction, one usually uses ,(comma) as a way to delimit words. To be compatible with the moveBatch.php syntax, we need to perform a substitution task:

sed -i "s/,/|/g" template_replacement.txt

Move pages to its proper names

After the replacement file is ready, one can simply run the moveBatch.php script to change the page names.

php ../maintenance/moveBatch.php --r="load template data" --noredirects template_replacement.txt

Note: The original instruction on the MediaWiki manual shows an --u=user option. The string user should be a user name in the database that you are trying to load this data. For simplicity, --u option can be ignored most of the time. If you insist using this option, make sure that you know a user name that already exists on the database, otherwise, it will throw exceptions.
