Joern Kottmann commented on OPENNLP-776:
----------------------------------------

Sorry for the confusion is was speaking all the time about 
serializable-basemodel.patch and not serialization_proxy.patch.

> Model Objects should be Serializable

> Marking model objects (ParserModel, SentenceModel, etc.) as Serializable can 
> enable a number of features offered by other Java frameworks (my own use case 
> is described below). You've already got a good mechanism for 
> (de-)serialization, but it cannot be leveraged by other frameworks without 
> implementing the Serializable interface. I'm attaching a patch to BaseModel 
> that implements the methods in the java.io.Externalizable interface as 
> wrappers to the existing (de-)serialization methods. This simple change can 
> open up a number of useful opportunities for integrating OpenNLP with other 
> frameworks.
> My use case is that I am incorporating OpenNLP into a Spark application. This 
> requires that components of the system be distributed between the driver and 
> worker nodes within the cluster. In order to do this, Spark uses Java 
> serialization API to transmit objects between nodes. This is far more 
> efficient than instantiating models on each node independently.
