In a SharePoint environment, such metadata fields are called columns. They are used to create specific views in your libraries or to use in the search engine.
SharePoint comes with a strong tool to centrally manage metadata, managed metadata. It will offer some great practical uses for your business. Consistent use of metadata, improved content discoverability, increased flexibility and the possibility to easily translate, add synonyms to, reuse and pin keywords are just a few of the many benefits of managed metadata.
