I'm new to DDD and trying hard to understand some of the concepts. How do you determine in your domain what objects are Entity objects and which ones are Value objects, and how exactly are they treated differently?

How do you choose between implementing a value object (the canonical example being an address) as an immutable object or a struct?
Are there performance, semantic or any other benefits of choosing one over the other?

Can someone post an example of how I get an instance variable value that is a double? I tried using the object_getIvar() function but that didn't go very well because it seems like this function is only good for variables that return objects and not scalar...

I'm trying to design a pretty simple app and am getting myself a bit confused with Hibernate's definition of entity and value objects (as defined in Chapter 4 of Java Persistence with Hibernate).

That you're going to fetch objects by the string value of an attribute, do not use a list, use a dictionary.

Question 1: The for each loop to that foreach.
Use a copy constructor.
By defualt should make a local copy of the value into your '$k=>$object' - any changes localwell, you simply clone your object.

Obviously I am wrong in saying that DDD is similar to EAV/CR in usefulness, but the only difference I see so far is physical tables build for each entity with lots of joins rather than three tables and lots of joins.
This must be due to my lack of DDD...

I'm seeking advice on doing the following in a more pythonic way.
Consider:
class MyObj(object): def __init__(self): self.dict_properties = {}
Suppose I've got a list which contains multiple MyObj instances:

You could reach for operator and try to compose an attrgetter... .
Mylist.sort(key=lambda x: x.dict_properties['mykey'])
is way simpler, and faster.
I'd just do:
mylist.sort(key=lambda o: o.dict_properties["kykey"])
You could also overide cmp on the class .
