Possible MetaData Limitations in HIVE

After some extensive research and testing in HIVE, it appears that there might be an issue in trying to 'ask' HIVE to acknowledge that a document (object) is part of a collection of objects - the idea of a validation document being part of a larger validation process.

The principle issue (which may still be resolved) is that you can use metadata fields such as 'relate' (Dublin Core DC scheme) to establish a link between documents (relationship), but when you search for a document, HIVE has no facility to represent this relationship to the user - insofar as there is not a 'plus' sign logo that enlightens the user to other related documents (that are related but they might not have directly searched for).

The 'relate' (DC) should allow the reference between documents using terms such as 'ispartof' 'isrelatedto' - A reference to a related resource.

So to clarify - you can reference other documents but with no facility to represent this relationship (only an alphabetized list is produced) - you will only know of this relationship if you were the one that created it and searched for it through the metadata search facility.

I will endeavor to ascertain whether this situation can be resolved in the future as I am currently using a HIVE test server.

In the time being, I will continue to look at mapping the required document metadata to established metadata standards schema used by HIVE.
