that's the mysterious bit for me Stephen! how to construct a query that will
return all resources such that:
isInCategory category_mindmapping
is satisfied.
Also wasn't sure why the general search only returned the last relationship
type in the RELS-EXT when there are three in the system.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
