It all goes via one interface ISerialization which has a serialize() method which serializes the context into whatever output format and it has a content_type attribute which defines the content type of the output (default is LLSD). There is a ISerialization adapter configured for both capabilities (from dicts) and PlainPasswordCredentials. See agentdomain.py for how to use it. For deserialization there is a IDeserialization utility now. It is registered under the name of the content type it can deserialize. It produces dicts always. Use it like this: deserializer = getUtility(IDeserialization,name="application/llsd-xml") dict = deserializer.deserialize_string(s) Tests for this component will be added later but they are indirectly tested by the login test which passes.
