dating extraction: keep and handle dating items bundled together when they come from a single entry in the sections
- dating sections in iDAI.objects can have multiple entries
- each entry can contain several dating items
- the information which dating items stem from a shared entry in the sections is lost right now
- since different entries can refer to different instances of the entity (i.e. original and replica) the information is valuable
- thus we should maintain the information in the structure of the hub data
several tasks follow from this reasoning
