Anchors are metadata entities that group other entities together. They act like containers. This means, for example, if the anchor is deleted then the entities linked to the anchor are also deleted.
The anchor relationship is specific to particular types of metadata entities. So not all metadata entities linked to an anchor are deleted when the anchor is deleted.
For example, a personal profile may contain links to specific Assets. When the personal profile is deleted, the assets are not effected except that they loose their relationship to the personal profile.
