Categories and Keywords allow you to create hierarchical taxonomy trees that reflect the structure of the content that you offer online and the relationships between the content elements. Content is classified within the taxonomies using keywords (metadata). You can navigate the content repository using taxonomies, which gives easy access to the content you are looking for.
Product catalogs are easily managed, and since content items can be classified against multiple taxonomies, you can dissect your catalog in multiple ways. Taxonomies can be BluePrinted in the same way as other content for language-specific, multi-site or multi-channel management.
