Zineng Yuan commented on ATLAS-1318:
------------------------------------
Thank you for comments. The above deletion logic looks good to me and the same
logic can apply to hierarchical type as well.
Two thoughts:
1) Since the deletion now is a cascading behavior and it might impact many
levels and types, to play safe in case that a user mistakenly delete all T_Ref
types, I would like to put some constraints on the server side. The purpose is
to prevent a user making unexpected mistakes. This rest API fails if any T_Ref
with entities exist and it forces the user to manually delete all T_Ref
entities before moving on. The error msg must be informative and mentioned all
T_Ref types with entities. Although it requires a user to engage, it
validates a user's purpose.
Also, since the requirement and implementation are largely clear, could you
assign this ticket to the community? I am also willing to take the
responsibility if needed.

> Project: Atlas
> Issue Type: Bug
> Affects Versions: 0.7-incubating
> Reporter: Zineng Yuan
>
> I am trying to extend Atlas Type System by adding custom data type. However,
> when I found a type name was misspecified and needed to be recreated, I can't
> find a Restful Delete API.
> Question is does Atlas expose a Delete API for custom data types/attributes?
> Without this delete API, it's difficult to rely on Atlas as a meta store to
> extend custom data.
> Please do suggest how to recreate a data type in this case. Thank you!
