New CN Interfaces http://mule1.dataone.org/ArchitectureDocs-current/apis/CN_APIs.html
--------------------------------------------------
org.dataone.service.cn.tier1.CNCore
org.dataone.service.cn.tier1.CNRead
org.dataone.service.cn.tier2.CNIdentity
org.dataone.service.cn.tier2.CNAuthorization
org.dataone.service.cn.tier2.CNRegister
org.dataone.service.cn.tier3.CNReplication (renamed from org.dataone.service.cn.tier4.Storage)


New MN Interfaces http://mule1.dataone.org/ArchitectureDocs-current/apis/MN_APIs.html
--------------------------------------------------
org.dataone.service.mn.tier1.MNCore
org.dataone.service.mn.tier1.MNRead
org.dataone.service.mn.tier2.MNAuthorization
org.dataone.service.mn.tier3.MNStorage
org.dataone.service.mn.tier4.MNReplication


Old Interfaces
--------------------
org.dataone.service.cn.CoordinatingNodeAuthentication
org.dataone.service.cn.CoordinatingNodeAuthorization
org.dataone.service.cn.CoordinatingNodeCrud
org.dataone.service.cn.CoordinatingNodeDataReplication
org.dataone.service.cn.CoordinatingNodeQuery
org.dataone.service.cn.CoordinatingNodeRegister

org.dataone.service.mn.MemberNodeAuthentication
org.dataone.service.mn.MemberNodeAuthorization
org.dataone.service.mn.MemberNodeCrud
org.dataone.service.mn.MemberNodeHealth
org.dataone.service.mn.MemberNodeReplication


1) Common Library d1_common_java
-----------------------
types  (datatypes and exceptions)
interface defs
Jibx Extention Code
no implementation code
Constants
ObjectFormatService* (remove bcse already defined in CNCore)

2) Common Utility Library d1_util_java
---------------------------------
Helper Serializer/Deserializers  (currently ServiceTypeUtil ?)
MimeMultipart implementations
StreamingUtil
EncodingUtilities
ObjectFormatServiceImpl* (eliminate, use CNCore instead)


3) Common CN Library  d1_cn_common
-----------------------------
NodeId Generation (place this in the CN implementation of node registration)
MetadataPackageAccess

Libclient library
----------------------
4) d1_libapi_java
org.dataone.client.net
D1Url
RestClient
D1RestClient
org.dataone.client.serviceImpl
D1Node / MNode / CNode - implementations of service API
ObjectFormatServiceCache (implemented as part of CNode)
-
5) d1_libclient_java
D1 LIB CLIENT  == BatchLibCLient
(refactor MNnode to remove D1Client dependency, MNode will depend upon CNode)
* Mnode dependency on CNode will be problematic for testing validity of a new member node
  (the whole web-testing idea) - the CNode parameter passed in should be allowed to be null.
 
DataPackage
D1Object
D1Client
- 
ITK Client Pkg
???


split libclient into two peices,  shared lowlevel functionality.

Scenaros
--------------
* A. Products: 1, 2, 3, 4, 5

B. Products: 3, 1, (2, 4, 5)

C. Products: 3, 1, (2, 4), 5

D. Products: 3, 1, 2, (4, 5) 

2 depends on 1 (serializers)
3 depends on (1,2), used by CN implementation only
4 depends on (1,2), used by CN, MN, ITK
5 depends on 4( depends on 1,2), used by ITK, MN, and perhaps CN

n.b.:  method redundancy (serialization / deserialization) between TypeMarshaller and ServiceTypeUtils.

elephant in the room: D1_schemas is one namespace
  -- need to refactor to limit cascading impacts of versioning

Type schemas were merged around 2010-11-18
