Redirect request to CPS-Core (Using java interface) with dataspace 'NCMP-CmHandle-Operational-Data'
Issues/Decisions
| # | Questions/Open Issues | Notes | Decision/Answer | |||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | Proposed Rest endpoint to read data "http://{cnmpHostName}:{ncmpPost}/ncmp/v1/ch/{cm-handle}/data/ds/ncmp-datastores:operational (Hardcoded)" | /ds is datastore | /../ncmp-datastores:operational (Hardcoded) | |||||||||||||||
| 2 | Will be using GET http methods to expose rest endpoint ? | Yes, as per current passtrough equivalent endpoints | ||||||||||||||||
| 3 | What if restendpoint contains ../options ? | Team preference: Ignore if it is there in endpoint. | Need confirmation from kieran mccarthy [ Kieran ] NCMP cannot interpret options. This was added for passthrough case. Suggest to ignore 'options' | |||||||||||||||
| 4 | Do we need to append "?xpath=/" with proposed rest endpoint to fetch root elements or should it be added while redirecting to cps core(using java interface)? | As per original Implementation Proposal/Study | Use "?resourceIdentifier=/" that would be mapped to xpath. | |||||||||||||||
| 5 | Do we need to append "&include-descendants=true/false" with rest endpoint or should be added while redirecting to cps core(using java interface)? | CPS-Core does support a &include-descendants query parameter | Need to discuss with kieran mccarthy [ Kieran ] It would be good to include this as a new parameter in the NCMP URI. Behavior should be that the default if omitted from URI is 'false' meaning no decendants returned in the default case. | |||||||||||||||
| 6 | Do we need to support only RootXpath or can accept xpath from endpoint to filter result ? | Support any xpath in this scope. xpath (resourceIdentifier) is compulsory | ||||||||||||||||
| 7 | To query/redirect to cps core we need 3 or 4 attributes how it would be mapped? |
| ||||||||||||||||
| 8 | If we pass topic query param with this endpoint should we use async ? | Probably, but implement as separate user story with different (lower) priority ?! | Need confirmation from kieran mccarthy |
Note : CPS Core java interface :
public ResponseEntity<Object> getNodeByDataspaceAndAnchor(final String dataspaceName, final String anchorName, final String xpath, final Boolean includeDescendants)
