-------------------------------------
[~apoorvnaik] Thanks Apporv - I have added more detail - it should make more
sense now.

> Add constraints to JAVA API for the Glossary. There are some constraints that
> can be captured using the constraints in the type model. For the Glossary
> API, there are restrictions that cannot be captured in the type model. I am
> thinking of constraints like:
> - policing that we do not allow a category to be updated to have a parent as
> one of its descendants.
> - policing that we do not allow a category from another glossary to be added
> under out category
> - policing that we do not allow a category to be updated such that the
> category tree contains categories from more than one glossary.
> - restricting terms under a category to have unique names (we need to get
> consensus as to whether this is something we would like)
>
> These sorts of restrictions would need to policed in the Java code - as there
> is no place for them in the model. For the Glossary, we are looking to add a
> new OMAS layer around the base Atlas entity APIs.
