- If we instead make the calls on the individual services, how do we model the notion of a handler service in our REST/SOA world, so that a client can get the handler for a VocabularyItem reference and then operate on it?
Should vocabularies define not just allowed relations, but also required relations?
For cases like life-science taxonomy, we may want to preclude orphan VocabularyItems, and so require parent or child linkage. Perhaps this is something that the individual services should implement as part of the their semantics, rather than trying to generalize this. For now, we will not rty to mode this generally, and we can see if some common themes emerge from experience.
