You could use something like "@Entity" like the EJB spec has. But I guess the purpose of the Pojo cache is to provide fine-grained replication, so "@Replicated" or "@Replicable" or something would be okay. "@Replicable" means "capable of replication, which might make more sense than "@Replicated" which sort of seems to mean that it's already been replicated ... which isn't exactly true. For inheritence, it seems appropriate to add an attribute rather than a separate annotation, for example: @Replicable(instanceOf=true) or @Replicable(subclasses=true) There might be some sort of relation term that would fit better than "instanceof", that means "child classes also".
