-   Tape Link
-     A Tape Link connects a :term:`Tape Library` to one or more :term:`Partitions <Partition>`,

+     Tape Link
+      A Tape Link represents a single tape link associated with a DPM-enabled
+      :term:`CPC`. Tape links define pathways to :term:`Tape Library` storage
+      that can be attached to :term:`Partitions <Partition>`.
+
+      When a tape link is attached to a partition, its fulfilled resources are
+      virtualized and the partition's view of them is represented by
+      :term:`Virtual Tape Resources <Virtual Tape Resource>`.
+
+      Tape Link resources are top-level resources whose conceptual parent is
+      the :term:`Console`; a linked tape library is identified by the
+      ``tape-library-uri`` property of the tape link.
