The Review and Submit section of the Add/View/Edit Identity Provider (Service Provider) page lets a Site Administrator (SA) preview an entity's metadata in its SAML form. It is also where the SA perform a number of metadata management functions:

  • Submit an entity's metadata for publication in the InCommon metadata
  • Un-publish a entity's metadata from the InCommon metadata
  • Delete the entity from Federation Manager 

These options appear as they are appropriate for the status your entity is in in Federation. Visit Understanding entity status in Federation Manager for additional information on possible entity status in Federation Manager.
