To tell everyone what your interests are, go to your profile editing page and enter your interests/tags. If a tag you entered already exists, you get associated to that tag. If it does not, a new tag will be created.
For an example of using tags to share interests, see the School demo site "horses" tag
After writing a blog post, users are allowed to add user defined tags about the post. These are usually keywords relevant to the post separated by commas. If a tag you entered already exists, you get associated to that tag. If it does not, a new tag will be created. If one tag is associated with interests and a blog post, the tag page will show both.
Users who can access the course and have the course capability moodle/course:tag are able to tag the courses. This capability is given to teachers and managers by default. If user is also allowed to edit course settings, the "Tags" section will be added to the form in Course administration > Edit settings, otherwise they will be able to set the tags on the separate page Course administration > Course tags. Courses is the only content type where capability to tag is separated from capability to edit the entity. (See the Course tagger role for more information.)
Other users may then search tags from Navigation > Site pages > Tags and find tagged courses or use the tag cloud block.
Teachers can tag course activities and resources when setting them up.
Users are able to add tags to the wiki pages while editing them. Tags will be displayed together with the page, however it is not yet possible to search wiki pages by tags.
Users are able to add tags to the questions in the question bank while editing them. It is not yet possible to search questions by tags.
Each tag in Moodle has a page associated with it. The tag page brings together users, courses and blog posts related to that tag. A tag has a description, links to related tags, a list of users associated with that tag and Moodle blocks with resources related to it.
If a user has the capability to edit tags, a link "Edit this tag" will appear in the tag page. The tag may be edited to add a description and related tags.
If the tag name or its content is inappropriate, a user may click on the "Flag as inappropriate" link to report that (capability to flag tags is required). This will allow those responsible for maintaining the good use of the tags functionality to take appropriate action, such as deleting the tag. See Managing tags for details.
If the user has the capability to edit blocks on tags pages, he will be able to change the configuration of the blocks that appear on the tag page.
The related tags that appear in a tag page comes from two sources:
- User suggested related tags, entered in the "Related tags" field.
- System suggested related tags, which are automatically calculated. Tags that appear a lot together ("Computers" and "Software" for example) will be considered related.
A very effective way of viewing all tags is in a tags block, or "tag cloud". A unique feature of tag clouds are that the size of each tag is related to the number of items associated with it. The larger the tag, the more items associated with it.
The Search tags page in Navigation > Site pages > Tags allows you to look for existing tags.
