Tim Perkins commented on AVRO-2299:
-----------------------------------
We had similar requirements when implementing an Avro schema registry (in Ruby):
[https://github.com/salsify/avro-schema-registry]
We needed a normalization that included all of the fields relevant to schema
resolution and compatibility checking.
We wrote a gem in Ruby to calculate this form, which we named Resolution
Canonical Form:

> {panel:title=Avro Schema Reserved Keys:}
> "doc", "fields", "items", "name", "namespace",
> "size", "symbols", "values", "type", "aliases", "default"
> {panel}
> AVRO also supports user defined properties for both Schema and Field.
> Is there way to get the schema with reserved property (key, value)?
> Input Schema:
> {code:java}
> {
> "name": "testSchema",
> "namespace": "com.avro",
> "type": "record",
> "fields": [
> {
> "name": "email",
> "type": "string",
> "doc": "email id",
> "user_field_prop": "xxxxx"
> }
> ],
> "user_schema_prop": "xxxxxx"
> }{code}
> Expected Plain Schema:
> {code:java}
> {
> "name": "testSchema",
> "namespace": "com.avro",
> "type": "record",
> "fields": [
> {
> "name": "email",
> "type": "string",
> "doc": "email id"
> }
> ]
