just a point of clarification: NCSTRL was not directly the model for OAI,
at least architecturally.
OAI has more in common with:
- RePEc (
http://www.repec.org/)
- SODA (
http://www.dlib.org/dlib/march99/maly/03maly.html)
and similar architectures.
A subset of the Dienst protocol gave us a starting ground for defining a
harvesting protocol, but even that has been relaxed to allow Dienst and
OAI to progress independently.
Most OAI service providers will probably assume a distributed storage
model, because it is certainly easier to build. But technically OAI is
agnostic with respect to centralized vs. distributed storage of data.
OAI focuses only on metadata.
Regarding centralized vs. distributed, I would submit CiteSeer
http://citeseer.nj.nec.com/cs
as an exemplary DL that seems to have resolved the tension between the two
models - providing both links to distributed copies and cached centralized
copies.
