Subject taxonomies can be used to tag content with "flat" information about the content's topic (such as Olympic Games 2012). They can also enrich assets with hierarchical categorization for fine-grained drill down navigation (such as Hardware / Printers / Laser Printer).

Subject Taxonomies are represented by the content type CMTaxonomy.

Location taxonomies allow content to be associated with one or more locations. Location taxonomy hierarchies can be used to retrieve content for a larger area even if it is only tagged with a specific element within this area ("All articles for 'USA'" would include articles that are tagged with the taxonomy node North America / USA / Louisiana / New Orleans).

Location taxonomies are represented by the content type CMLocTaxonomy which inherits from CMTaxonomy and adds geographic information for more convenient editing and visualization of a location.

The taxonomy administration editor can be used to create a taxonomy and build a tree of keywords.

The taxonomy administration editor displays taxonomy trees and provides drag and drop support and the creation and deletion of keywords.
