Service example for Tree/Hierarchy annotations ?

Dear Members,

do you know a vocabulary-based SEGW project in SAP standard which manage hierarchical annotations so that a tree view is rendered on the UI ?

Thanks, Attila

P.S.:

I would like to generate a tree at UI side, but instead of using JSOn Model, I want to use sap.ui.model.odata.v2.ODataTreeBinding. To do this, I would like to check an example, but in our system only several Fiori apps are implemented. If you know one application, then we can install it of curse. Just tell me the name
