New page:
Abstract base type for nodes in a structured node hierarchy.

== Definition ==

- jcr:created (DATE) autocreated protected INITIALIZE

== Description ==

Together with ["nt:folder"] and other subtypes this node type implements the Composite design
pattern for storing structured node hierarchies. Node hierarchies based on ["nt:hierarchyNode"]
subtypes differ from hierarchies based on ["nt:unstructured"] in that each ["nt:hierarchyNode"]
node has a distinct character (e.g. branch or leaf node) and semantics whereas ["nt:unstructured"]
nodes have no specified interpretation

This node type is normally only used as a base for other node types, as there is usually little
point in creating a node whose only content is the creation date and other metadata specified
by possible mixin types.

== Related node types ==

 * ["nt:folder"] has ["nt:hierarchyNode"]s as child nodes
 * ["nt:hierarchyNode"] is the base type of ["nt:file"], ["nt:linkedFile"], and ["nt:folder"]
