##### DEPRECATION
Deprecation of fields and messages are natively supported by protobuf options.
The standard "Deprecation" aspect is used for a dataset generated from a protobuf `message`.
Field deprecation adds a tag with the following urn `urn:li:tag:deprecated` (red, #FF000).
```protobuf
message msg {
extend google.protobuf.MessageOptions {
repeated string deprecation_note = 5620 [(meta.fld.type) = DEPRECATION];
uint64 deprecation_time = 5621 [(meta.fld.type) = DEPRECATION];
}
}
message Message {
option deprecated = true;
option (meta.msg.deprecation_note) = "Deprecated for this other message.";
option (meta.msg.deprecation_note) = "Drop in replacement.";
option (meta.msg.deprecation_time) = 1649689387;
}
```
The field deprecation tag works without definition in `meta.proto` using the native protobuf option.
```protobuf
message Message {
uint32 my_field = 1 [deprecated = true];
}
```
## Gradle Integration
An example application is included which works with the `protobuf-gradle-plugin`, see the standalone [example project](../datahub-protobuf-example).
