A node is uniquely identified in the Repository via its node reference, also commonly referred to as NodeRef.A node reference points to a store and a node in that store. A node reference has the following format:{store protocol://store identifier}/UUIDsuch as for example workspace://SpacesStore/986570b5-4a1b-11dd-823c-f5095e006c11.
The first part is the store reference and the second part is a Universally Unique Identifier (UUID) for that store. Node references are used a lot in the available APIs so it is good to have an idea of how they are constructed.
