/dataspaces/{dataspaceName}/anchor/{anchorName}/list-node

Implementation Proposal

Create list-node  with one or more elements elements

Implement the functionality to support multiple nodes addition using data fragment with node-list root element.

REST layer (incl openapi update)

• uri:
  • (CPS) POST /dataspaces/{dataspaceName}/anchor/{anchorName}/list-node
  •  (NCMP) POST /cm-handle/{cmHandle}/list-node
• parameters:
  • xpath - parent node xpath (mandatory)
  • JSON data fragment via request body
• response 201 on success

Service layer

• parse JSON string into collection of DataNode objects

Persistence layer

• find parent node by parent node xpath (throw not found exception if absent)
• add all provided elements to parent node
• persist (throw already exists exception on unique constraint violation)

Delete all list-node elements

Implement the functionality to support multiple nodes addition using data fragment with node-list root element.

REST layer (incl openapi update)

• uri:
  • (CPS) DELETE /dataspaces/{dataspaceName}/anchor/{anchorName}/list-node
  •  (NCMP) DELETE /cm-handle/{cmHandle}/list-node
• parameters:
  • xpath - list node xpath (same as list-node element but with no key attribute definition)
    i.e. /root/parent/list-node
• response 204 on success

Service layer

• validate xpath referenced list-node element (?)

Persistence layer

• delete all by dataspace and anchor and xpath starts with provided xpath to list-node (this includes all children as well)
