  • Dataspace is a logical separation of data

    • Used in conjunction with the ‘owner’ concept. xNF proxy will not expose this.

  • Anchor is a logical separation of data within a dataspace

    • Used to distinguish (xNF) instances with of the same model

    • Relates directly to the xNF id in AAI

  • Schema set is a representation of the xNF model

    • Preserves the original format to avoid collisions and poorly defined models

    • Relates to the VNF Descriptor (VNFD) in ONAP


  • Yang Resource is used to store the original content of the yang resource file (part of schema set)

    • 'name' is the original resource name, it is not the module name or namespace!

  • Fragment is a YANG container or YANG list

    • Main data storage table. Attributes are stored in jsonb field

  • Relation preserves YANG cross references


  • Schema Node provides fast access to relevant YANG meta data
