Tags allow students and teachers to connect different types of content on the site.
The following areas may be tagged:
- Activities and resources
- Forum posts (new in 3.3)
- Glossary entries (new in 3.3)
- Books (teachers only - new in 3.3)
- Quiz questions
- Wiki pages
- Blog posts (including external blog posts)
- User interests (displayed on your full profile page)
See Using tags for more details.
Note that the list of possible tag areas is configurable by a site administrator - see Managing tags. The site administrator can also create sets of tags, such as a collection of standard tags for tagging courses. When a user clicks on a tag, the tag page displays only items with that tag in the same collection.
Users who can access the course and have the course capability moodle/course:tag are able to tag courses.
Activities and resources in a course may be tagged from their set-up screen.
