A dataspace is a logical separation of data within the CPS. Dataspaces are specified created by data owners.
An anchor is a logical separation of instances of data instances compliant/described to the same model (set of YANG modules). Anchors are created by data owners.
Anchors Anchor and dataspaces dataspace concepts are described in a presentation here.
An owner is an ONAP component that is responsible for data in the CPS. Responsibility includes deciding how data is exposed to other ONAP components. Options being:
- Data is exposed via µService APIs – no direct access to data via CPS interfaces
- Data is exposed via CPS interfaces – requires registration/discovery and access control to be implemented (FUTURE)
Data ownership and access control are the mechanisms provided by CPS for ONAP to avoid uncontrolled coupling in the data layer.
