Terminologies/Acronyms

The terminologies/acronyms below are commonly used throughout this document. The list below defines each term regarding how it is used in this document:

Term	Definition
MDR	management data repository
CMDBf	specification for a CMDB that federates between multiple MDRs[1]
federating CMDB	the CMDB that federates between MDRs, offering a common access point to clients and correlating identifying record data
CMDB	configuration management database

Purpose

We needs to add support for adopters intending to register a federating CMDB with COSMOS framework. This enhancement will include reusable code for adopters intending to provide a server/client side implementation of a federating CMDB.

Implementation details

There is already code in place for adopters to use when implementing an MDR. The following MDR plug-ins will be extended to provide support for a federating CMDB:

org.eclipse.cosmos.dc.mdr
org.eclipse.cosmos.dc.mdr.client
org.eclipse.cosmos.dc.mdr.common

Three additional plug-ins will be introduced, each of which will be an extension of its MDR counterpart:

org.eclipse.cosmos.dc.federating.cmdb
org.eclipse.cosmos.dc.federating.cmdb.client
org.eclipse.cosmos.dc.federating.cmdb.common

On server side two operations will be introduced:

• Register
• Deregister

On client side few variations of registration. All variations will also apply to deregistration:

• Registration based on a request
• Registration of all items/relationships of a set of MDRs
• Selective registration based on a CMDBf query on a set of MDRs
