[WIP]

  • kbv:ItemHolding blir en normaliserad nod som "reifierar" kbv:heldBy
    • Och kbv:heldBy ska ha domain kbv:ItemHolding.
  • kbv:Item blir ptg:abstract och bas för bestånd respektive exemplar. kbv:hasComponent kan inte i sig vara ett bestånd (inget "bestånd hela vägen ner"); därför inför vi kbv:SomeItem som är ett eller flera faktiska exemplar.
    • kbv:SomeItem behöver vara "tydligt otydlig" och inte ptg:abstract. (Om vi inte lyckas precisera att alla kbv:hasComponent i bestånd är enskilda exemplar. Men det är både osannolikt och troligen inte önskvärt - det finns nog många "har två av denna på hylla X och resten i låda Y i källaren").

…e-item

Make it possible to have linked SingleItem (sv: "Exemplar") inside Item hasComponent.

    SingleItem is in collection none instead of hold so that we don't get any of the special handling for holdings
        => it is possible to have multiple SingleItem records per library
        => it is not involved in MARC export except as an embellished hasComponent of a regular holding record
    Access control for holdings is extend to all subclasses of Item instead of just collection hold
        i.e. only owning library + global registrant can write SingleItem

Later on Item might be replaced by ItemHolding for the holding, with SingleItem and SomeItem for 1 vs many items.
