Hi,
which optional features of JDO does it support?
there are 22 optional features in JDO 1.0 specification, I think most
important difference between implementations (and to determine which one is
better that the other one) is for support of standard optional features,

optional features are:

1- Transient Transactional
2- Non-transactional Read
3- Non-transactional Write
4- Retain Values
5- Restore Values
6- Optimistic
7- Application Identity
8- Datastore Identity
9- Non-durable Identity
10- ArrayList
11- HashMap
12- HashTable
13- LinkedList
14- TreeList
15- TreeSet
16- Vector
17- Map
18- List
19- Array
20- Null Collection
21- Change Application Identity
22- JDOQL
