David Radley commented on ATLAS-1984:
-------------------------------------
As per my dev list comment, I like the way of using an existing attribute as a
display name; I wonder if we should have display name as a flag on
AttributeDef, if there were multiples specified then we could concatinate or
police to only allow one. This would allow people to create a new attribute
called displayAttribute if they like or use an existing attribute like name in
the GlossaryCategory case. It would also mean that classifications,
relationships and structures could have display names.
I wonder if the displayName is not specified for Entities, then we could
default it to the first unique attribute value if there are unique attributes,
if not then we could default to the qualified name for Referenceables. If we
wanted we could sample the data values and look for the most unique and use
that!
If we do this - I think that it would make sense to enhance AtlasObjectId to
show the list of display attributes as well.
Also i suggest we call AtlasRelatedObjectId, AtlasRelationshipObjectId. I think
we should just use the word 'relationship' in all namings - and only introduce
new terminology like 'related' if there is a new meaning we are looking to
show.
> Use AtlasRelatedObjectId to refer to relationship attributes during
> create/update/delete of entity
