I think the strength of the schema-free approach is that it allows one
to create a schema-agnostic infrastructure: the Learning Registry can be
used for data of whatever schema. Rather than data of no schema I think
we will see data of many varied schemas.
Hopefully the metadata that is put in for inBloom will propagate to
other parts of the Learning Registry network and be available there to
anyone who cares to interpret it. There is a contrast with practice so
far in sharing metadata e.g. through OAI-PMH in that each individual
infrastructure node (e.d. an aggregator doing the harvesting) has only
worked for a pre-agreed schema. Often these agreements have been, in
effect, closed-shops.
There's a transport analogy if you like, some transport facilities will
only take standard containerized cargo; motorways are built so that this
type of cargo can be transported but so can pallets in the back of a
white van.
