Fedora Content Models for the National Science Digital Library Data Repository (NDR) (PowerPoint)

... Information Network Overlay

a digital library (particularly science DL) is more than just documents: it's data, orgs, people, services

all (primary resource) objects named with handles in overlay

... including Access Controlled API

interested in very rich granualarity and access control

some of this is still theoretical, not in production yet

1 million metadata records in Oracle (Dublin Core) will = a digital object in Fedora
there are ancillary objects around the metadata = about 2.1 million objects

NSDL is not a content library, it is a metadata library
but it will be possible to add content e.g. lesson plans

each object turns into about 60 triples = about 60 million? 120 million triples

NDR currently one Fedora repository, will become ? federated repositories

want to build representations of people in the NSDL, so that you can build a reputation system for those people
"this person is expert in X"

can use proai to expose using oai anything that you can connect with a disseminator?

make sets using aggregation
