David Radley commented on ATLAS-1186:
-------------------------------------
I have been thinking about the recent discussions around adding terms to the
glossary and Madhan Neethiraj's helpful comment on Jira ATLAS-1344.
The Glossary uses the entity V1 API including references to
AttributeDefinition. A category has a parentid property and an edge to it's
parent. Children and parents interrogate the edge to and use projections to get
properties populated. A side effect of this is that we need to delete all the
edges before we delete a glossary category entity or taxonomy entity.
The new entity v2 API introduces the ability to have optional multiple
relationships for atlas structure types. The thought is that maybe this
mechanism could be used for the category children. It seems to me that we would
want to change the BaseResourceDefinition to create ClassTypeDefs for the
Glossary Category Taxonomy and terms. I have raised ATLAS-1410 for this.
If we want one code change per issue - I suggest the following order will make
the changes easier to manage, consider, and review (and less merging).
- 1186 - with the current design
- 1486 - switch the glossary over to use v2 - simplifying the edge management
on deletes.
- 1382 - implement terms as entities.
I could do a bigger single checkin if that is what the reviewers / community
need.
all the best, David.
