STATUS
Issues/Decisions
Scope
- Support should include create/delete/update from a dmi plugin.
- Read public properties for a cmhandle
Analysis
The dmi-plugin introduced in Istanbul release has the ability to add a databag of properties (cmHandleProperties) on creation of a cmhandle.
These properties are only shared between NCMP and the dmi-plugin. In addition, they are only understood by the dmi-plugin and are never used by NCMP.
Once the cmhandle is created in NCMP with the properties attached, then any subsequent requests sent to dmi-plugin for a cmhandle will include these additional properties.
In Istanbul release NCMP does not expose these cmhandle properties except on the ncmp < - >dmi-plugin interface.
It should be possible for dmi-plugin to register properties that it wishes to be exposed to application clients of the NCMP interface.
The proposed interface changes required on the dmi-plugin interface are listed in the table in Interface Proposals below.

json attributes: - "dmiPlugin" resolvable servicename
- "createdCmHandles" used for initial cm handle registrations or subsequent
cmhandle creations - "updatedCmHandles"
Used for updates to cmhandles. Same structure as for create handles - "removedCmHandles" array of cmhandles that have been deleted
from the network (no additional properties
| - Is the URI being updated to {ncmpRoot}/ncmpDmi/v2/ch ?
- Update to an existing interface
- New proposed additions in red
