IT:AD:SharePoint:Concepts:MetaData

* Metadata is Data about Data * Metadata is for Classification

• Content to Content (Relation/Contextual/Hinting/etc.)
• Content to People (Personalization)
• Findability (Search & Organization)
  • eg: Page that finds all things tagged with XXX

* Two kinds of MetaData:

• Folksonomy = Tags created by End Users, on the fly
• Taxonomy = Tags created by admins, etc. creating structure of site
• MSDN Ref

In SP 2007, had:

• Content Type
  • A Site Content Type is a Container for Site Columns
  • MSDN
  • Create by:
    • [Site]/[SiteActions]/[Site Settings]/[Modify All Site Settings]
    • [Galleries]/[Site Content Types]/Create
    • Name, Description, etc.
    • Select Parent ContentType
      • Note that Special Content Types group contains content types that change the behavior of your list or library when added.
    • Select Parent Content Type
    • Select Group

      • Done.

In SP 2010, have the same, plus:

• Term Stores
  • A Container/Set of a Term Sets, which is a Container/Set of Terms
  • A Term Set (eg: 'Topics') could be contained by Term Store ('Corp Topics')
  • A Term can be just a Tag (eg: Topic A, Topic B, Topic C)
• Managed Metadata
  • KeyWorkds
    • Keywords
    • Enterprise Keywords

How this all comes together is that the first time you create a List, you just create a list, without thinking about it. In the background, a ContentType is created (containing Site Columns).

A more formal way, and less mangled, process is to Site Admin, and create a Term Store first.
