+``LinkObject`` is a :ref:`Data packet <data>` of a dedicated ``LINK`` type and specially-formatted content part, listing a set of delegations (name prefixes and the associated priorities) that should be used to guide forwarding of the Internet packet.

+Selected Delegation
+~~~~~~~~~~~~~~~~~~~

+The SelectedDelegation field indicates the index of the delegation in the attached ``Link`` that was chosen by a downstream forwarder(s).

+Link Object
+-----------
+
+The Link Object is a specialized form of a :ref:`Data packet <data>` packet, defined as follows::
+
+    LinkObject ::= DATA-TLV TLV-LENGTH
+                     Name
+                     MetaInfo (.ContentType = LINK)
+                     LinkContent
+                     Signature
+
+    LinkContent ::= CONTENT-TYPE TLV-LENGTH
+                      Delegation+
+
+    Delegation ::= LINK-DELEGATION-TYPE TLV-LENGTH
+                     Preference
+                     Name
+
+    Preference ::= LINK-PREFERENCE-TYPE TLV-LENGTH
+                     nonNegativeInteger
+
+
+Link Object is a data packet, whose content contains a list of one or more name delegations: a pair of name and the associate priority.
+The semantical meaning of the delegations depends on the specific use.  For example, when LinkObject is used as part of Interest packet, each delegation implies that the requested Data packet can be retrieved by forwarding the interest along the delegation path.  Specifics of the forwarding logic for Interests with ``LinkObject`` will be defined in a separated document.
+
+The list of delegations in ``LinkContent`` SHOULD be ordered by preference value in ascending order (i.e., the lowest value first).
+
+In a LinkContent, each Delegation SHOULD have a distinct Name.
