+h2. Resource
+
+Links are an extensible way to describe relationships between Arvados objects and metadata about individual objects.
+
+Each link has, in addition to the "Common resource fields":{{site.baseurl}}/api/resources.html:
+
+table(table table-bordered table-condensed).
+|_. Attribute|_. Type|_. Description|
+|head_uuid|string|The object being described or acted on.|
+|tail_uuid|string|The origin or actor in the description or action (may be null).|
+|link_class|string|Type of link|
+|name|string|Primary value of the link.|
+|properties|hash|Additional information, expressed as a key→value hash. Key: string. Value: string, number, array, or hash.|
+
+h2. Link classes
+
+Some classes are pre-defined by convention and have standard meanings attached to names.
+
+h3. permission
+
+See "permission links":{{site.baseurl}}/api/permission-model.html#links section of the permission model.
+
+h3. tag
+
+A **tag** link describes an object using an unparsed plain text string. Tags can be used to annotate objects that are not editable, like collections and objects shared as read-only.
+
+table(table table-bordered table-condensed).
+|_. tail_type→head_type|_. name→head_uuid {properties}|
+|→Collection           | _tag name_ → _collection uuid_|
+|→Job                  | _tag name_ → _job uuid_|
