Site Columns

Site Column is a SharePoint term to describe a list column, or metadata field that can be shared across all libraries and lists in any Site in a Site Collection. 

In our Semaphore solution a “Semaphore Classification” type site column is provided that adds taxonomy support to SharePoint lists.

This is a dynamic column that provides powerful taxonomy support to SharePoint users :

• Items can e manually labelled using a taxonomy tree browser
• Items can e manually labelled using a full text search over the taxonomy including the main terms and any synonyms.
• Items can be automatically classified with terms from the taxonomy.
