Semantic Tasks

Semantic Tasks (a.k.a. ST) is a Semantic Mediawiki extension that provides task notification and reminder emails with the help of semantic annotations.

In contrast to the built in notification systems in MediaWiki (watching pages), this extension can be used to trigger notifications without user interaction with the MediaWiki system, e. g. by filling in a form (using the PageForms extension) where a user name is entered in a form and in the resulting template the respective properties are set to trigger a email notification (see below).

Requirements

• PHP 7.3 or later
• MediaWiki 1.35 or later
• Semantic MediaWiki 3.2 or later

Installation

The recommended way to install Semantic Tasks 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:

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-tasks": "~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( 'SemanticTasks' );

Step 4

You must run a cron job e.g. once a day to trigger the reminders to be sent by e-mail. To do so add the following line to your crontab to execute the respective script every day at 12:

Step 5

It is possible to adapt the names of the properties for your wiki via configuration in the "LocalSettings.php" file. This is an optional step if you would like to use different property names. This is the list of default settings:

• $stgPropertyAssignedTo = 'Assigned to';
• $stgPropertyCarbonCopy = 'Carbon copy';
• $stgPropertyTargetDate = 'Target date';
• $stgPropertyReminderAt = 'Reminder at';
• $stgPropertyStatus = 'Status';
• $stgPropertyAssignedToGroup = 'Assigned to group';
• $stgPropertyHasAssignee = 'Has assignee';

Configuration

• SemanticTasksNotifyIfUnassigned - (default: false) If set to true will notify users being unassigned from tasks
• $stgNotificationFromSystemAddress - (default: false) If set to true will use $wgSiteName and $wgPasswordSender for notification emails From field

Usage

Notification emails

They are sent as soon a page is saved. The system looks for the [[Assigned to::*]], [[Carbon copy::*]] and/or [[Assigned to group::*]] properties.

Groups

Create a group page with properties [[Has assignee::*]] and then assign the group to the task with [[Assigned to group::*]] property.

Status

Set Status to [[Status::Closed]] to inform assignees that the task has been closed and to disable notifications and reminders.

Reminder emails

Once the script execution is triggered via cron the software looks for the [[Reminder at::*]] and the [[Target date::*]] property. It then sends reminders to all the assignees.
