Implementation Proposal

We will be augmenting the existing CPS-Core endpoint /v1/dataspaces/{dataspace-name}/anchors/{anchor-name}/list-nodes?xpath=/

REST Layer

• DataRestController.java

  • Add a check in addListElements to see if the parent xpath is a root path ("/").  If root node, create passed list element as top node. Else add passed list element to parent xpath node.

• DataRestControllerSpec.groovy

  • Add test for scenario above

Service Layer

• CpsDataService.java

  • Overload saveListElements method with implementation for no parentNodeXpath

• CpsDataServiceImpl.java

  • Overload saveListElements method with implementation for no parentNodeXpath

  • buildDataNodes and call new method storeListElements in Persistence Layer

Persistence Layer

• CpsDataPersistenceService.java

  • new method storeListElements

• CpsDataPersistenceServiceImpl.java

  • new method storeListElements, converts datanodes to fragment repository and saves it.
