In Elium, tags of the same group can be organised into a coherent set called an "Category" (e.g., the tags "France" and "Belgium" belong to the "Country" category). The other tags, which do not belong to any group, are referred to as orphan tags.

Every category has different characteristics:

optional or mandatory (at least one tag of this category must be applied to content for it to be valid)
open or restricted tags (the list of tags in this category is predefined by the administrator and cannot be enriched by contributors)
universal or dedicated to certain defined spaces

Except for restricted categories, contributors have the ability to create new tags at the time of tagging, thereby enriching existing categories or the list of orphan tags. It is the responsibility of system administrators to keep the tag dictionary up to date.

Tags are collective. Everyone can see the tags attributed by all users.

🤓 We advise you to:

limit the number of categories
create the most cross-functional categories
check the proliferation of tags with the help of closed suggestion lists, meaning by limiting the categories and preventing the creation of tags in these categories
avoid mandatory categories that do not encourage contribution
give categories short and explicit names
