As a user of POMBA, I want an API that I can call that takes as input a service instance id and returns back the decomposition of the service in the form of resource types and identifiers for the VNFs and resources that make up the service.  The API may return additional information, but this is not required.

Input

service instance id

Action

look up that service into A&AI exploiting the best possible available interfaces

Output

Returns a decomposed list of resources involved in that service, that is then suitable for performing additional operations on. In particular, it needs to be sufficient to run network discovery.

• resource type
• resource identifier

Error conditions include the following

• Malformed request
• Missing mandatory parameters
• service id not found
• random system errors

Note that this API shall support Basic Auth.  Additional stories shall track security enhancements.

Definition of Done

•  Compliant to the ask above
•  Support for all ONAP best practices
•  Code checked in, use documented on Wiki
• Demo to working group
