Semantic Extra Special Properties

Semantic Extra Special Properties is a Semantic MediaWiki extension that adds some extra special properties.

Requirements

• PHP 7.3 or later
• MediaWiki 1.35 or later, tested up to MediaWiki 1.39
• Semantic MediaWiki 3.1 or later, tested up to SMW 4.1

Installation

The recommended way to install Semantic Extra Special Properties is using Composer with MediaWiki's built-in support for Composer.

Note that the required extension 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-extra-special-properties": "~3.0"
	}
}

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-extra-special-properties": "~3.0"

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( 'SemanticExtraSpecialProperties' );

Step 4

Add the configuration parameters to the "LocalSettings.php" file according to your requirements below the call to wfLoadExtension added in step 4.

Step 5

This step may be skipped in case you are installing this extension for the first time to the respective wiki. If this extension is being upgraded from an version earlier than 2.0.0 you have to change your configruation in the "LocalSettings.php" file according to the consise migration guide.

Step 6

Run the "update.php" maintenance script to ensure that property tables are properly initialized.

Usage

The annotation process for predefined properties is mostly done in the background and therefore does not need any special interaction from a user but "LocalSettings.php" for SESP need to be enabled.

For details about available configruation parameters, please have a look at the configuration document.

Exif property names

You might want to check the labels for Exif properties. They are defined in MediaWiki core and being reused by SESP. It is possible that property names you already use will be prefedinied properties after activation of SESP. On the sepcial page "System messages" you can search for all messages with the prefix "Exif". One example: there is the message Exif-source that has the label "Source". If you use a property labeled "Source" already, you should change MediaWiki:Exif-source from "Source" to "Exif-source".
