CentraSite is installed with a number of predefined taxonomies. Some of these taxonomies are "core taxonomies" that belong to CentraSite itself.

Other predefined taxonomies are installed to support the use of CentraSite by products such as the webMethods product suite. These taxonomies belong to other products, which expect the taxonomy definitions to remain unchanged. Modifying or deleting these taxonomies in CentraSite can lead to inconsistencies or errors in the product that uses the taxonomy. For example, if you modify or delete a taxonomy that is used by the webMethods product suite, components such as the webMethods API-Portal may not be able to capture the original API metadata from CentraSite. You must not modify these predefined taxonomies.
