Item is replaced by multiple items

[milanmajchrak]

I'd like to ask if replacing the item with multiple items is considered a valid status. I'm struggling with these Items:

• https://lindat.mff.cuni.cz/repository/xmlui/handle/11858/00-097C-0000-0023-1AAF-3 It is replaced by two items
• https://lindat.mff.cuni.cz/repository/xmlui/handle/11234/1-2375 It is replaced by two items
• https://lindat.mff.cuni.cz/repository/xmlui/handle/11234/1-3185 it replaces three items
• https://lindat.mff.cuni.cz/repository/xmlui/handle/11234/1-4595?show=full it replaces three items

Generally, it is a valid status for both replaces and replaced by. Item can replace multiple items if it has all their data and some extra annotation on top of that. So the relations is more than pure haspart. That'd be the case for PDT-C and the treebanks it consolidates.

Item can be replaced by multiple items if it splits into multiple projects (like dspace now having fe and be separately).

Though, with those concrete examples, you've posted, I'd need to check my records. CzeDLex surprises me a bit.

It's kind of mentioned in https://github.com/ufal/clarin-dspace/blob/8a6ba5c98547942d7115b74cf4978e0b29ca50e4/dspace-rest/src/main/java/org/dspace/rest/ItemsResource.java#L1076-L1086

Yes, that can happen and here it really did happen. For instance there were two succesors of PDT 3.0, because one kept the data and added some more annotation (analysis), and the other project merged the parent treebank with more data.

So it can happen both ways: father with more children, and also a child with more parents (merging datasets into one).
