Purge and Update entities/attributes
Based on type / attribute and/or a filter (q) entities to be deleted can be selected. To delete attributes another parameter is needed. Whether the projection parameter pick is suitable or a new parameter needs to be found needs further investigation.
Examples: PURGE
- ?type=XXX&q=supportedProtocol.expiresAt<2032-01-12T00:00:00.000Z
- ?type=XXX&q=supportedProtocol.expiresAt<YYY&pick=supportedProtocol.
Investigate whether we want to also support update.
