#9 Values handling model research

[Przemek]

for now we have STRING as a default value. We may try to introduce more advanced model - more types. It is even possible to serialize any Java object to xml/json and store as bytes. The question is how to handle that via REST as the client may be non-Java based. Another problem how to query such objects? Probably would have to be deserialized in filters to be applicable in expressions. Interesting problem to solve, probably a few choices to pick.
