Class RegistryMetadata

org.gcube.informationsystem.registry.RegistryMetadata

public class RegistryMetadata
extends Object

A registry's record of the models it holds. Every type belongs to exactly one of them: information-system-model, the domain model installed from the classpath, or the runtime model holding the types created through REST. Each counts the schema writes on its types since the last migration, next to a global count of every schema write. It is not a model Element: it describes a registry, not the information it holds. A System Dump carries it, so that the dump can be read with this model alone.

Unknown fields are ignored, so that a reader built on an older version still reads what a newer one writes.
