Current Web vs Semantic Web Linked data principles
Why should libraries care about linked data?

“Linked Data refers to data published on the Web in such a way that it
is machine-readable, its meaning is explicitly defined, it is linked to
other external data sets, and can in turn be linked to from external
data sets.”
(Bizer, Heath, and Berners-Lee 2009)
• Software and hardware agnostic
• More creative applications based on library metadata
• Opportunities for library cataloguing and innovation
• Lack of awareness
• Lack of examples
• “Linked data is inaccessible” mindset, it’s only for experts
• Linked data require changing the foundation of library metadata
• Privacy
• Rights management

Linked data
Semantic Web
URI
Everything is given a URI as a
name
HTTP
The URIs are dereferenced over the HTTP protocol
RDF
•RDF describes things through triples
•Subject-Predicate-Object
For the LD community
• High quality linked data
from libraries
• Librarians have been creating
high quality metadata for a
long time
• Library created linked data can
function as a high quality base
for the LD community
For libraries
• Library data can be accessed by
search engines
• Disambiguation
• Ability to perform complex queries
• Accumulation of data from many
different sources, data combinations
• Decrease in the amount of local
records
• Creation of new services
• Libraries can better meet user
expectations and needs
Thoughts...
• Libraries can lead linked data efforts
o Librarians are experienced in collecting, curating, accessing,
preserving and delivering data to users (Miller, 2011)
• Libraries as well as the LD community will benefit
• It is time for libraries to go where the users are The Internet
o No more “closed” data silos
o No more limited data usability
o Interoperability
