COSMOS Reconciliation Taxonomy
The reconciliation taxonomy defines a basic set of resource types and the properties typically used to identify instances of each resource type. The purpose of the taxonomy is to describe enough information about a resource (e.g., a computer system) to determine whether two management data repositories have data about the same resource, even given that each repository uses a different data model. For example, some identifying properties about a computer system are manufacturer, model, serial number, system board UUID, and primary MAC address. Such a taxonomy could be used in different contexts, including implementations of the CMDB Federation specification and launch in context scenarios.
The use of a reconciliation taxonomy is a compromise between trying to get the entire IT industry to adopt a single data model (considered to be impractical) and defining no common data at all, which would require a bespoke model mapping for each pairwise integration of management data repositories.
The terminologies/acronyms below are commonly used throughout this document. The list below defines each term regarding how it is used in this document: note to MJ: change this however you like, I included as an example
|MDR||management data repository|
|CMDBf||CMDB Federated is a specification for a CMDB that federates between multiple MDRs|
|federating CMDB||the CMDB that federates between MDRs, offering a common access point to clients and correlating identifying record data|
|CMDB||configuration management database|
|Query service||MDRs make data available to Clients via a Query service. Queries may select and return items, relationships, and/or graphs containing items and relationships.|
to MJ: I can fill in some of this if you like since I can include the parts that are fixed due to the Eclipse process
I can also provide info as to where to find it in CVS
