Best way to define handle values

[netzknecht]

I noticed that lunar uses user-defined and subsequently changeable handle values ​​in various places, some of which are also created from translatable strings.

In my opinion, this is not particularly problematic as long as they are not used to reference relations between data records. However, this is the case with the Attribute models in conjunction with the attribute_data collections. Careless changes to the handle values ​​can then lead to inconsistent references.

So, it would be better to use automatically generated and unchangeable IDs for the assignment between Attribute model and the referenced data in an attribute_data collection or perhaps, use a dedicated database relation to store attribute data, even if it involves additional database queries.

Because a user defined handle is more comfortable for human to handle :-), it should be also available but with the recommendation to define uniformly in English.
