Subject: [Engine-devel] alias in disk instead of name
The problem we caused by using alias in disk instead of name is break
of search-by-name paradigm
in engine.search dialect, not sure why we do not want forcing disk
name to be unique [1],
but lack of "name" in disk search is does not look good in my view.
thoughts?
[1] can be easily achieved via appropriate can-do-action
verification.
Names by definition are not unique IDs, thus it should not be enforced.
What would be the auto naming conversion to ensure uniqueness with plain text?
Would you change these on import/export?
And so on...
You should treat the name as a tag/alias that if you bothered to update, probably means
something to you, if not then you don't care anyhow and will not search by it anyhow.
So it's up to the user what to assign.

(re)use the term "name" and came up
with "alias", to avoid confusion.
