4. Data is legally not reusable!
A piece of content or data is open if
anyone is free to use, reuse, and
redistribute it — subject only, at most, to
the requirement to attribute and share-
alike.

6. Workflows are distributed!

9. First steps
Jan. 2010 The CERN Library publishes its book
catalog under CC0
Mar. 2010 First German libraries publish
bibliographic data under CC0
May 2010 German National Library launches
Linked Data Service for authority files
Jun. 2010 Mannheim University Library launches
Linked Data Service for bibliographic
data
Jul. 2010 hbz launches Linked Data Service for
institutional data
10. First signs of an emerging path
Aug. 2010 SWB publishes Open Data
Aug. 2010 hbz extends Linked Data Service to
include bibliographic data
Nov. 2010 DNB & hbz launch a hub for Linked Data
in cultural heritage institutions
Nov. 2011 DINI-AG KIM recommends open data
practices for library data
Dec. 2011 BVB & KOBV release catalogue data
Jan. 2012 DNB adds bibliographic data to their
Linkd Data Service and switches to CC0
13. d-nb.info
● Linked Open Data for
○ Name Authority
○ Subject Headings
○ Corporation Authority
○ National Bibliography
● Fully integrated into the website
● Provides dumps of the entire datasets
● No SPARQL endpoint so far
15. lobid.org for Organisations
● Assign HTTP URIs to identify libraries
and related institutions.
● Deliver information about the
institutions in HTML/RDFa and RDF
● Aggregate up-to-date information
such as opening-hours directly from
the libraries
● Provide editing capabilties to
generate RDF (pre-alpha)
17. culturegraph.org
● Identification of manifestations by
shared URIs
● Resolving of these URIs, returning all
associated URIs
● Lookup of URIs by search over other
identifiying properties
● Publication of the cross-linkage as
Linked Open Data
19. Licencing and Linking
● CC0 is emerging as the default licence
● Data is being reused, e.g. by Wikipedia
● The German National Library and four
out of six library networks have begun
to publish (Linked) Open Data
● Linkage is increasing, e.g. inbetween
the individual services and to DBpedia
● Those Services are more or less
experimental and mostly still evolving
20. Content and Models
● So far, predominantely bibliographic &
authority data has been published
● Vocabularies used are not library
specific (DC, BIBO, SKOS, ...)
● More specialized vocabularies such as
ISBD are gaining traction due to
increasing efforts by e.g. the IFLA
● Additional aspects such as holding and
availability information are being
modelled in DAIA by GBV.
21. International context
● International trend towards LOD
○ Library of Congress
○ National Library of Sweden
○ British Library
○ National Library of Spain
● System Vendors seem to keep working
on Walled Gardens
○ WorldShare (OCLC)
○ Alma (Ex Libris)
23. New research policy
In January 2012 the German Research Foundation
issued a funding programme for the realignment of
regional information services. At the core, this
programme is calling for
● Web Integration,
● Open Interfaces,
● Vendor Independence
● and Open Licencing
in order to enable interoperability with Web-based
applications for researchers.
24. Possible outcome
The Linked Open Data paradigm could
become the central organizational and
architectural principle of the future
German information infrastructure; it
puts data "on" the Web, makes it
legally reusable, employs standards
known beyond the library domain and
enables distributed workflows.
