Extension:Proofread Page

The Proofread Page extension can render a book either as a column of OCR text beside a column of scanned images, or broken into its logical organization (such as chapters or poems) using transclusion.

The extension is intended to allow easy comparison of text to the original and allow rendering of a text in several ways without duplicating data. Since the pages are not in the main namespace, they are not included in the statistical count of text units.

The extension is installed on all Wikisource wikis.



Extension

 * 1) Download the files from Git or download a snapshot (select your version of MediaWiki) and place the files under $IP/extensions/ProofreadPage
 * 2) Add to the end of LocalSettings.php:
 * 3) Add the required tables to the database; on the command line, enter:  (Note: Your designated database user needs to have CREATE rights on your MediaWiki database.)
 * 4) Installation can now be verified through Special:Version on your wiki

Thumbnailing
The extension links directly to image thumbnails which often don't exist. You must catch 404 errors and generate the missing thumbnails. You can do this with any one of these solutions:  Set an Apache RewriteRule in .htaccess to thumb.php for missing thumbnails:  or set the Apache 404 handler to Wikimedia's thumb-handler. This is a general-purpose 404 handler with Wikimedia-specific code, not simply a thumbnail generator.   For MediaWiki >= 1.20, you can simply redirect to thumb_handler.php:   Or in apache2.conf :  

WARNING: There is an .htaccess file in the images directory that may interfere with any .htaccess rules you install.

Namespaces
ProofreadPage create by default two custom namespaces named "Page" and "Index" in English with respectively ids 250 and 252.

Their names are translated if your wiki use an other language. Full list.

You can customize their name or their id: Create namespaces by hand and set their ids in LocalSettings.php using $wgProofreadPageNamespaceIds global. You will do something like:

Configuration

 * You need to create MediaWiki:Proofreadpage_index_template in order to display index pages
 * In order to use the page quality system, it is necessary to create four categories. The names of these categories must be defined in s:Mediawiki:Proofreadpage_quality1_category to s:Mediawiki:Proofreadpage_quality4_category.
 * Ensure that you have installed Extension:ParserFunctions

Creating your first page

 * Before following these steps ensure you have followed the instructions in Using DjVu with MediaWiki.
 * Create a page in the "Page" namespace (or the internationalized name if you use an not-English wiki). For example if your namespace is 'Page' create 'Page:Alice in Wonderland.djvu'
 * Create the corresponding file for this page File:Alice in Wonderland.djvu
 * Create the index page 'Index:Alice in Wonderland.djvu'
 * To edit page 5 of the book navigate to 'Page:Alice_in_Wonderland.djvu/5' and click edit

Roadmap
Thibaut Horel aims to improve this extension, fixing bugs and adding features.
 * Go over Mediawiki 1.19 problems:
 * create tickets for unsolved ones and estimate the amount of work needed. Before Saturday March 10th
 * fix the problems
 * Review and integrate already existing patches:
 * Review requested features:  create tickets for importants ones. Get in touch with other big Wikisources (de, it, ...) to see if they have specific pages to track requested features
 * Other projects to look at, get in touch with: Captcha-OCR, PagedTiffHandler

OAI-PMH
Since 28904, the extension has an OAI-PMH API for index pages.

The API is implemented in a new special page Special:ProofreadIndexOai using a basic OAI-PMH protocol with Simple Dublin Core (oai_dc) and Qualified Dublin Core (prp_qdc).

S small metadata typing system has also been implemented and Special:ProofreadPageIndexOaiSchema provides an XML schema for Qualified Dublin Core because OAI doesn't provide one. The associated xml namespace is http://mediawiki.org/xml/proofreadpage/qdc/

This repository will provide the data stored in index pages, while the repository of the OAI extension provides metadata about pages. For example, the entry for Index:La Fontaine - The Original Fables Of, 1913.djvu will have as dc:creator "Jean de la Fontaine" in this repository and "User:Zephyrus" in the repository of the OAI extension. https://en.wikisource.org/wiki/Index:La_Fontaine_-_The_Original_Fables_Of,_1913.djvu
