You must have a plan to manage and organize your
information. This is one of the most important parts of any SharePoint
implementation. The plan will help you ensure that information is easy to find
and that content is easy to access within your sites. Your information and the
management of it is only as good as the metadata applied to the content and the
search capabilities designed to index and query it. A taxonomy defines and
controls the way a Web site is organized, what things are named, and how people
find information. In short, a taxonomy makes it easier to organize and find
things on your SharePoint site.
SharePoint uses content types for
information asset types and term sets for coherent tagging of
information. Content types define classification
hierarchy of information built from a set of fields defining the metadata. Some metadata fields require the use of a
controlled vocabulary defined in the managed metadata service.
