2. Why worry about learning
resources?
2010-09-27 LAK '12 2

3. Stovepiped repositories hold data and
share through pipes like OAI-PMH
Metadata grows stale as people refuse to
update or even add at the outset
Data exhaust is wasted: it’s not powering
anything
Learning resources languish “on the shelf”
Data is locked in and locked down

4. Stovepiped repositories hold data
and share via pipes...
Vs.
Data is shared in the open for
aggregation, amplification,
analysis…

5. Metadata grows stale as people
refuse to update or even add at the
outset (“We can’t plan on good
metadata.”)
Vs.
Enrich the data with social usage
data (paradata) to add nuance to
metadata

6. Data exhaust is wasted−it’s not
powering anything
Vs.
Data exhaust is collected to power
the social life of learning
resources

the shelf
Vs.
Resources live in a rich
ecosystem

Vs.
Democratization/Liberation of
data

9. Data is shared in the open for
aggregation, amplification, analysis…
Learning Registry is a distributed
system that permits sharing of metadata
about learning resources
…developed through an open community
process that engages learning resource
creators, publishers, curators, and
consumers.
2010-09-27 LAK '12 9

10. Learning Registry is a store-
and-forward data exchange
network—not a destination
website, search engine, or
repository—upon which diverse
user services can be built.
Enrich learning resource data with
paradata to add nuance to metadata…

the social life of learning resources

13. Resources live in a rich ecosystem

16. Many learning resource systems
can be connected into the Learning
Registry network through publish
and consume APIs
Learning Object Repositories,
Teacher Portals, Search tools,
Learning Management Systems,
and Instructional Improvement
Systems.

17. Currently the Learning Registry
mainly contains metadata, published
+ from a number of collaborators, about
resource classification and usage data.

18. Built on CouchDB document distribution
system: easy to set up new nodes and
replicate
Metadata agnostic: uses JSON key-value
pairs to encapsulate metadata in any
schema
Social usage data modeled on NSDL
Com_para and activity streams
Uses URL to identify resources; submitter
identity verified by digital signature
2010-09-27 LAK '12 18

19. Relationship Mining: surface relationships
between people based on their attention to
resources. What institutions, portals, or groups
of users have shared/curated the same
resource?
User experience: ratings indicate satisfaction
and so provide feedback to developers.
User profiling: what types of actors use which
resources?
Trends in attention to different resources could
be computed using social metadata date ranges.
2010-09-27 LAK '12 19

20. Recommendations by clustering users or by
building a social network graph and then
recommending resources among a cluster or
network.
Feedback to developers about the utility of their
resources, about who adapts them and how, and
could eventually cause “widespread sharing” of
learning resources to learners at the appropriate
time.
