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. For the syntax, see s:mul:Wikisource:ProofreadPage. It is also used on Wikilivres.

Requirements and recommendations

 * Access to the command line is required if running the update script (maintenance/update.php) from the web browser fails (documentation here and here).
 * If you want to use DjVu files (optional but recommended), a native DjVu handler needs to be available for configuration. See also Manual:How to use DjVu with MediaWiki.
 * In addition, use of ProofreadPage is highly improved by the use of the following extensions:
 * LabeledSectionTransclusion (strongly recommended)
 * Poem
 * PdfHandler (may require additional PHP packages) — adds PDF support
 * PagedTiffHandler
 * ParserFunctions

Extension

 * 1) Install LabeledSectionTransclusion (not required but strongly recommended)
 * 2) Download the files from Git or download a snapshot (select your version of MediaWiki) and place the files under $IP/extensions/ProofreadPage. Warning: Current master branch of the git repository is only compatible with with MediaWiki 1.21 and above. In order to use ProofreadPage with MediaWiki 1.19 or 1.20 use the REL1_19 branch.
 * 3) Add to the end of LocalSettings.php:
 * 4) 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.)
 * 5) 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 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. .

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

 * In order to use the page quality system, it is necessary to create four categories. The names of these categories must be defined in Mediawiki:Proofreadpage_quality0_category to Mediawiki:Proofreadpage_quality4_category.
 * Ensure that you have installed Extension:ParserFunctions

Configuration of index namespace
The configuration is a JSON array of properties. Here is the structure of a property in the array, all the parameters are optional, the default value are set: The data parameter can have for value: "type", "language", "title", "author", "translator", "illustrator", "editor", "school", "year", "publisher", "place" or "progress".
 * You need to create MediaWiki:Proofreadpage_index_template in order to display index pages. This page is a template that receive as parameter entries of the edition form.
 * You need to create MediaWiki:Proofreadpage_index_data_config that contain the configuration of the index form. This new configuration page overrides MediaWiki:Proofreadpage_index_attributes and MediaWiki:Proofreadpage_js_attributes.

Creating your first page (example with DjVu)

 * 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'
 * Insert the tag in the Pages field to visualize the page list
 * To edit page 5 of the book navigate to 'Page:Alice_in_Wonderland.djvu/5' and click edit

Syntax
This extension introduces the following tags: and.

OAI-PMH
Since 28904, the extension has an OAI-PMH API for index pages. This 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). This repository provides the data stored in index pages. [//wikisource.org/wiki/Special:ProofreadIndexOai?verb=ListRecords&metadataPrefix=prp_qdc Example in oldwikisource]. It is based on MediaWiki:Proofreadpage_index_data_config (see Configuration of index namespace section), using especially "data" and "type" configuration entries.

Sets based on MediaWiki categories can be configured in Mediawiki:Proofreadpage_index_oai_sets that contain a JSON array like:
