Depends on how many requests the service has to accommodate. Up to a point, it's no big deal. After a certain point, servicing lots of calls gets expensive and bang for the buck is brought into question. My bigger concern would be getting data encoded/structured consistently. Even though FRBR has been around for a long time, people spend a lot of time scratching their heads about really basic stuff (e.g. what level something belongs on) when dealing with real world use cases. And it's hard to automate tasks when the people aren't sure what the machine needs to do. In some ways, FRBR strikes me as the catalogers' answer to the miserable seven layer OSI model which often confuses rather than clarifies -- largely because it doesn't reflect reality very well. kyle On Wed, Oct 16, 2013 at 3:23 PM, Karen Coyle <[log in to unmask]> wrote: > Yes, that's my take as well, but I think it's worth quantifying if > possible.
