README

Semantic Image Caption (a.k.a. SIC) is a Semantic MediaWiki extension to support the generation of image captions from annotations.

Requirements

• PHP 8.1 or later
• MediaWiki 1.43 or later
• Semantic MediaWiki 7.0 or later

Installation

The recommended way to install Semantic Image Caption is using Composer with MediaWiki's built-in support for Composer.

Note that Semantic MediaWiki must be installed first according to the installation instructions provided.

Step 1

Change to the base directory of your MediaWiki installation. If you do not have a "composer.local.json" file yet, create one and add the following content to it:

{
	"require": {
		"mediawiki/semantic-image-caption": "~2.0"
	}
}

If you already have a "composer.local.json" file add the following line to the end of the "require" section in your file:

"mediawiki/semantic-image-caption": "~2.0"

Remember to add a comma to the end of the preceding line in this section.

Step 2

Run the following command in your shell:

php composer.phar update --no-dev

Note if you have Git installed on your system add the --prefer-source flag to the above command.

Step 3

Add the following line to the end of your "LocalSettings.php" file:

wfLoadExtension( 'SemanticImageCaption' );

Usage

Create a schema with the IMAGECAPTION_RULE_SCHEMA type to identify the default_rule and possible other rules to match a specific requirement for the generation of caption information.

Add caption annotations to images with a Text or Monolingual text type property (which is assigned to the caption_property in the schema).

Depending on the rules defined, properties used, and captions provided, embedded images will show captions generated from image page annotations.
