While adding the media, in this case an article, the user can:
Assign the media to one or many categories.
Assign tags to the media.
Enter content through a WYSIWYG (what you see is what you get) editor.
Choose if the system should do automatic linking. If this is done the system will locate all keywords predefined in the system and replace those with a link. Keywords and keyword target URLs are defined through a separate page. Automatic linking is very helpful for navigation and for improved search engine optimization (in case the knowledge base is publically available).
