Easy traversal against the triplestore

|---|---|
| Primary Actor | |
| Scope | |
| Level | |
| Story | a. bottom up: Given an object, list all the parents of all levels b. top down: For a collection, we would like to know hierarchical structure of the object, even the relationship stored on its children. would like to know how many children of the object and how many grandchildren for each of its children... c. statistical information for the objects with particular datastream on repository level: for example, we need to know how many items have a PDF file for a particular collection. A great many example queries that have proved useful in the past are documented here. |

I think this use case is satisfied by the external triplestore functionality documented in SPARQL Recipes.
