A repository contains a set of stores.   For example in alfresco there is the workspace store and an archive store.

A store has a store ref which is simply a way of identifying a particular store, think of it as the store's name.   Look at the StoreRef class for details.

A store contains nodes which are identified by NodeRef.     You can obtain details of the node from its NodeRef.

Nodes can be linked together by associations.    A store has a single root node which has a path of '/' and all the other nodes are linked below the root node in a tree.   Following the associations gives the "path" of the node.

node handle is probably a synonym for NodeRef.

Thank you. That clarifies lots of things. But if i may, i still have some more questions :

- If NodeRef identifies node, is it unique? Say I have a cm:content node, is this node has one an only one NodeRef throughout its life time?
- There's also FileInfo and qualified names (QName). What are those? and how are those placed in relation with Node and Store?

Thanks again.
