Overview: Classify your content using taxonomies
Using classifications, you can organize content items, such as news, events, and comments.

In Sitefinity CMS, there are two types of classifications:
- Simple list
Simple lists group content into a controlled set of categories. There is no relation between the classifications of the simple list. They are equal members of a single structure. - Hierarchical list
By using this kind of classification, you can group content in hierarchy on more than one level. Relationship between a top level entry and a subentry in the hierarchy can mean group membership or refinement of the top classification by a particular characteristic or feature.
EXAMPLE: Dogs can be one tag and Cats can be another. Both Dogs and Cats are simple lists, meaning that all items tagged with Dogs are equal members of Dogs structure, there are no relationships between dogs. On the other hand, you can have a category Animals, which has subcategories Dogs and Cats. This means that all cats are Cats and all dogs are Dogs, but also all cats and dogs are Animals.
IMPORTANT: Classifications are shared across different sites. If you are using multiple sites, changing a classification on one site will change the classification on every other site that uses it.
To view, create, edit, delete, and manage classifications, click Content » All classifications.
The system displays a list of the predefined classifications – tags and categories, together with all created custom classifications.
