18. An apparatus for replicating a portion of a content repository comprising: a graphical user interface (GUI) to receive a selection of a content item in a content repository and an input describing one or more desired relationship patterns for replication, the relationship patterns associated with an ontology describing logical relationships between the selected content item and other content items in the content repository, wherein the content items comprise digital documents, wherein the ontology is stored in one or more tags associated with one or more content items in the content repository; a semantic engine to identify the selected content item and related content items of the content repository to replicate to a target storage device based on a storage capacity of the target storage device, wherein the target storage device is separate from the content repository, wherein the related content items comprise a logical relationship with the selected content item based on the desired relationship patterns; and a replication engine to extract the identified content items and store the identified content items on a storage device.
