1. MultiCloud/VIM and CDS Integration  (Eric/Lukasz)
   1. Instantiation Alignment
      1. agreement is that the VM and CNF Building Block orchestration should be common with the only difference is that SO as part of Create Building Block shall call trigger MultiCloud/Vim adapter for helm creation for the pod. 
   2. LCM Action
      1. CDS shall call the multiCloud/VIm Openstack Keystone v3 API or k8S based API for LCM Cloud actions. 

Meeting Minutes:

1. Disaggregation à resource resolution ms from blueprint processor  (Primary --Alexis)
   • Resource resolution engine
   • Template engine generation
   • Decouple the Database management for persisting the resource resolution. [nice to have]
   • Database is outside of the mS For resource resolution. (mariagaleriadb)
   • Resource Resolution Context Key à
     • The resource tables shall be extended to store the resource keys  and configlet id
     • Alexis to make the change: Default to true for storing the configlet generation in the tables;
   • Resource resolution Component  need to be extended to support unassignment based on the data dictionary capabilities for unassign.
   • Alexis to provide POC implementation and provide feedback.
   • Revisit Brinda idea of device modeling using json path.
• Resource Resolution mS shall be created
• Self Service API shall forward the call to resource resolution mS
• Action Item:

1. Atomic Transaction—
   • Each Transaction  support rollback /Failure
   • Rollback include previously successful configlet download
   • All Device are lock until all the action are implemented.
   • Atomic Transaction should be supported in parallel; 
• For a given action within support configlet generation  and download for multiple

• Alexis Solution:
  • Commit confirm capability supported
    • Commit fails on 3^rd.
  • Commit Confirm success
  • Commit works for the first 2
  •  
  • Action
    • Support the capability of Commit Id Rollback (also can be supported but the team felt that disc is more likely—this implementation can be modeled.
  • Yuriy to create a US for testing the rollback activities as a roadmap item.
  • Dan T to provide a WIP patch of Om implementation of atomic transaction for Alexis to review.
  • General premise is to support a disconnect flow for rollback use case.
• NetConf Protocol
• CDS Platform capability for rollback is supported via imperative workflow and/or DG CDS failed action.

1. Resource Resolution for Ansible/Pyton: (read me on the flow to be provided by Alexis and functionality is there in onap). 
• Action Item:

• Yuriy to create a placeholder US for supporting the capability for persisting resolved resource using Ansible/Python script. The Ansible/Pything script shall call the resource resolution API to store the resource resolve context. Notion is that CDS is the source of truth for all resolved resource that is pushed to the network.
• Alexis to upstream it.

1. Building Block Orchestration using CDS Resource Assignment:
   • Assign:
     • have SO retrieve the CDS context using the A&AI self-link.
       • Sub-Option 1 
         • Retrieve the Resolved name/value pair context
       • Sub-Option 2 (Preferred)
         • Retrieve the Cloud Meshed Context 
       • Sub-Option 1 & 2
         • CDS will provide right link for retrieving the correct sub-option. 
     • have CDS Create either MD-SAL structure for SO to extract context as part of create
   • Option 1:  (preferred)
   • Option2:
• Bell , AT&T and other is looking a way to eliminate the resource accumulator template and simplify the resource resolution for cloud orchestration.
• The approach is to use the directly the CDS Building block for Service, VNF, VF Module                Assign and Unassign

• Option 1 & 2:
  • Partial assignment should be supported. Meaning that if the capability is already resolved and it has a value instance then it resource-resolution component shouldnt call the capability component for resolution.
    • Can be model in CDS similar to the current DG implementation.

• Unassign/Delete
• Have CDS unassign the capability using the unassign capability reference in the data dictionary.

1. SDNC Helm Chart Update

• Update CDS chart to be standalone.
  • Yuriy to create US for Abdel.
• Default CDS Chart to be Y
• Action Item:

1. MultiCloud , SO and CDS Integration

• Leverage the SO, SDNC, and CDS Building
• Multicloud to support the onboarding of the values.yaml via SDC
• Override values.yaml file will be a template
• CDS shall resolved resource in name value pair and SDNC shall persist in mD_SAL
• SO shall retrieve the SDNC context and pass it to MultiCloud
• MultiCloud shall mesh the override .yaml template with sdnc context and trigger HELM.
• Extended the CDS Integration to LCM Action and Helm Creation/Deletion.
• Action Item:
• Eric/Lukasz to help with the integration strategy for Frankfurt release.

Meeting Minutes:

5G Use Cases:
https://wiki.onap.org/display/DW/5G+Use+Cases+in+R6+Frankfurt

• REST Based Interface --> AI Interface.
• A1 to support Rest based protocol with content ---
• CDS with AI Interface using Python/Kotlin [more efficent--reactive/non-blocking]
  • https://github.com/onap/ccsdk-cds/blob/master/components/model-catalog/blueprint-model/uat-blueprints/pnf_config/Scripts/python/RestconfConfigDeploy.py#L35
  • https://wiki.onap.org/display/DW/Modeling+Concepts#Concepts-2026349199
• Does CDS need to support External Systems allocation for 5G use cases? Interaction with external systems is made dynamic, removing development cycle to support new endpoint.
• In order to define the external system information, TOSCA provides dsl_definitions. Link to TOSCA spec info 1, info 2.

SO and CDS Integration comment---:

• SO to CDS need to make sure we pass the namespace/endpoint.
• Extend Marco Building block flows to existing flow architecture with the hooks of scope and action. 
• Discuss Strategy towards SO Tosca Driven orchestration and integration with CDS (long strategy --Frankfurt)
  • Benjamin M, Steve S, Seshu S, Alexis , Dan T , Damian, Henry, Mac, Munir, Eric M , Yuriy , Shawn

Policy and CDS Integration: 

• # 1. Alignment between on the AAI notation used in policy (node.attribute) and CDS (attribute) - AAI properties can be extracted out of config-deploy-properties into its own aai-properties as a workflow input under config-deploy-request 
• # 2. CLAMP rendering possible actions supported by CDS + rendering of the input fields from CBA - Open API generated from the protobuff - Ingest the TOSCA yaml from CDS
• # 3. SO response back to CDS for selected params in order to store them: e.g. in cases where VNF management IP is not a static IP. - Use heatbridge information
• # 4. Distributed CDS or for multi-tenancy: placeholder for the name of CDS or an identifier to resolve a specific CDS instance (namespace) # 5. Spec for SLA for an end-to-end closeloop automation, existing data??

CDS UI Feedback

• Node Type --> Should have Tags/Labels that the UI should express as a function.
  • Node Type rename to Function.

• Workflow > Action
  • Do we need a MODEL of a workflow or should the UI implement the tosca model with the output that CDS uses? Verify with Brinda/Alexis.
  • Is there a way to hide the get_attribute and reuse the model from the modeling-->

   4   "attributes": {

   5     "assignment-params": {

   6       "required": true,

   7       "type": "string"

   8     }

• Formalized the DSL type a model catalog. --Make available in the UI.
  
  • https://wiki.onap.org/display/DW/Modeling+Concepts#Concepts-2026349199
  • Action: Yuriy to create a user story for adding the dsl type in the model catalog.

• Template Artifact --> Do we have a plugin for velocity, Jinga, XML, Json,
• Future --> Integration accessing the XML content from DG builder.
• DG Builder support XML should be converted to json--> Dan T

• Run Time Experience -->
  • Add a new UI for the Configlet and resource resolution [Nirvan].
