-------------------------------------
Summary: "displayname" schema attribute
Key: AVRO-3975
URL: https://issues.apache.org/jira/browse/AVRO-3975
Project: Apache Avro
Issue Type: New Feature
Components: spec
Affects Versions: 1.11.3
Reporter: Clemens Vasters
https://avro.apache.org/docs/1.11.1/specification/#names
The "name" attribute's permitted set of characters is, rightfully, constrained
such that it will cleanly map to most programming languages.
In data systems, especially in end-user-facing platforms, users ask for
structural elements of their data to be named in their own language and that
requires characters outside of the permissible set. Those user-given names
choices should be preservable in the schema even if the technical "name" is
produced from the user-defined name such that it conforms to the restrictions.
I therefore propose a formal "displayname" attribute to be defined for all
schema constructs that have names, which accepts an arbitrary UTF-8 string. The
constraint on that attribute is that the displayname MUST follow the same
relative uniqueness constraints as "name".
The presence of the "displayname" would have no wire-impact.
I understand that this can be introduced as custom metadata extension, but I
believe this is a common issue. We are more aware of internationalization
issues now than when such naming constraints were conceived.
