Workload Estimation
To be filled in with sizings for separate work efforts. These will likely be tracked as individual defects/enhancements. Below are some rough sizings based on the draft as of a few months ago. These will need to be revisited upon further review of the current draft.
Lines 854-858: Remove the matchedRecords attribute 2 days
Section 6: There will be a service profile defined, but its use is optional, so probably there is no impact to the COSMOS implementation. 0 days
<xpathExpression> will be renamed to <xpathConstraint> and moved inside <recordConstraint> in both <itemTemplate> and <relationshipTemplate>. There can be 0..* <xpathConstraint>
<xpathSelector> (similar to <xpathConstraint>) added to <contentSelector> xpath changes: UI 2.5 days core 2.5 days
Add <BagOfProperties> as a special 'record' type in which the content is expected to be a bunch of XML elements, and for which there is no schema for the entire <BagOfProperties> 2 days
Extend the service metadata to include indications that one record type is a "sub-type" (loosely defined) of another record type.
Extend the service metadata for relationships to include naming the source role and the target role, such as indicating which is the 'antecedent' and the 'dependent' from a CIM association service metadata changes: 2.5 days
Make <recordId> in <recordMetadata> optional, and therefore <recordMetadata> can also be optional. 1 day
Move the deregistration of records to the deregister operation. Today <register> in an update mode is used for this function, but it's clumsy. 5 days (affects example registration service so maybe some UI too)
A few schema changes for extendability, mostly adding xs:any in several places. 1 day
Add an operation for each service such as GetServiceMetadata() that returns the XML document defined in the service metadata chapter in the spec. 0 days
Schema namespaces change from cmdbf.org to dmtf.org. UI: 1 day core: .5 day
Totals:
- UI - 3.5
- Core - 16.5
- Combined - 20 person days

Purpose
This enhancement will update the COSMOS web UI, SDK, web services, handlers, and model to support the newest draft of CMDBf.
Requirements
- COSMOS must support the latest changes in the CMDBf spec draft
