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

documentsHyperlinks

Linking between data contained in documents

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
