Rich Data? Poor Data? Depends on…
Lars G. Svensson
Libraries and other cultural heritage
institutions have high-quality data
| 15 | Rich Data? Poor Data? | September 4, 20132
Metadata specialists are convinced that
this data could make (web) search better
| 15 | Rich Data? Poor Data? | September 4, 20133
There it is!
WOW!

Linked data is about connecting silos
(but those silos are not the problem…)

… they are just a proxy for another set
of silos (the model ones)

And that puts the burden on the
consumer (making them less prone to
use our data)

We need to talk about models, not only
about formats

The model underlying the GND (and thus
the GNDO) is entity-based
| 15 | Rich Data? Poor Data? | September 4, 20138
• Corporate Body
• Conference or Event
• Subject Heading
• Work
• Place or Geographic Name
• Family
• Person
For bibliographic resources we currently
have no model (but a common German AP!)

We can have several models for different
use cases or communities (and expressed
in different formats/syntaxes)

Thing
(It doesn‘t have to be like this…)
Somehow related to

OWL/RDF reasoning can take care of
semantic granularity only if the models
are compatible enough

So is the solution to build another great
model?

We don‘t need one great model, but
several small ones (those we can turn)
