Just wanted to say that, whilst I've been silent since my initial response,
I'm not sure I agree with all the viewpoints presented here.. From a point
of view of (for example, CultureGrid) I'm not sure what has been done could
have been pragmatically achieved soley with web crawling as it's described
in this thread. Don't have a problem with anything thats been written here.
It certainly represent a great cross-section of viewpoints. However, from a
jisc discovery perspective, I don't want to contribute to any confirmation
bias that we could dispose of pesky old OAI. I'd be interested in providing
a counter-point to any "Best practice" document that suggested we could.
