Managing the Knowledge Base

Liferay 7.4 U72+/GA72+

With Knowledge Base, you can draft product documentation quickly and organize it into hierarchies that end users can navigate. Add folders and nested articles to create the desired structure and order. Additionally, manage article and folder permissions to ensure only intended users can access your content.

Adding Folders

Open the Site Menu () and go to Content and Data → Knowledge Base.
In the Folders and Articles section (), click Add () and select Folder.
Enter a name and description.
Configure the folder’s permissions. By default, the View permission is assigned to the Guest role, meaning anyone can view the folder.
Click Save.

Managing Folders and Articles

After adding folders and articles, you can drag and drop them in the left side panel to organize and order your documentation. You can also click Actions () to access additional management options.

Note

For 7.4 U71/GA71 and earlier versions, Knowledge Base articles include a priority value. This value appears beneath the article’s title and determines its order in the Knowledge Base Display widget. You can configure this behavior via Knowledge Base System Settings.

Folder Options

Additionally, you can click Info () to toggle the information panel for the current folder.

While viewing an article, you can also click Info () to view article details and versions.

Scheduling Articles for Publishing

Release Feature

When creating or editing an article, you can schedule it for publishing at a specific date and time. While scheduled, the article only appears in the Knowledge Base application and does not appear in site pages.

If you edit a scheduled article and click Save, Liferay saves the article as a draft and cancels the scheduled publication. Alternatively, if you click Edit Schedule, you can choose whether to publish the article immediately or schedule it for publishing at a future date and time.

To use this feature, enable the LPS-188058 release feature flag.

Setting Review and Expiration Dates for Articles

Sometimes Knowledge Base articles are only valid for a period of time. For these situations, you can set expiration and review dates for Knowledge Base articles to help insure the integrity of your documentation. While set, Liferay checks Knowledge Base articles at a set interval for any articles that have reached their expiration or review date. It then sends notifications to the reviewers, owners, and subscribers. When an expiration date is approaching, Liferay notifies users that the article is expiring soon.

By default, articles are set never to expire or require review, but you can change this while creating or editing an article.

The default value is one year in the future, but you can select the desired date and hour. Users receive notifications for the article based on system mail and notification settings.

When an expiration date is reached, the Knowledge Base article cannot be used in sites. Users accessing the Knowledge Base article through a URL receive the 404 HTTP status. Additionally, an expired article cannot be modified unless the expiration date is set to a future value or expiration is disabled.

Reaching the review date does not affect the article. It only reminds users to review the article’s content.

Configuring Review and Expiration Notifications

Open the Global Menu (), go to the Control Panel tab, and click System Settings.
Under Content and Data, click Knowledge Base.
In the Service tab under System Scope, enter a check interval. This value determines the number of minutes between checks. By default, the value is 15 minutes.
Determine the number of weeks before expiration to send notification. Articles within this range are assigned an Expiring Soon label. The default value is 1 week.
Click Save.
Go to the Service tab under Site Scope.
Enable/Disable review and expiration emails.
Determine the content of review and expiration emails.
Click Save.
