org.modeshape.jcr.cache.NodeKey
An immutable unique key for a node within the {@link JcrRepository repository}'s {@link SchematicDb database}.
A node key consists of three parts:
1. A multi-character key uniquely identifying the repository's storage source in which this node appears;
2. A multi-character key uniquely identifying the workspace in which the node appears; and
3. A multi-character key representing the JCR identifier of a node, which is usually a UUID.
