Why LOD in Libraries?

Data is "off" the Web!

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.

Data formats are ancient!

?

Workflows are distributed!

The Story so far

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

First signs of an emerging path

Aug. 2010 SWB publishes Open DataAug. 2010 hbz extends Linked Data Service to

include bibliographic dataNov. 2010 DNB & hbz launch a hub for Linked Data

in cultural heritage institutionsNov. 2011 DINI-AG KIM recommends open data

practices for library dataDec. 2011 BVB & KOBV release catalogue dataJan. 2012 DNB adds bibliographic data to their

Linkd Data Service and switches to CC0

Some examples

DNB Linked Data Service

● 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

d-nb.info

hbz Linked Data Service

● 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)

lobid.org for Organisations

Linked Data Hub for cultural heritage institutions

● 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

culturegraph.org

Trends

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

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.

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)

What's next

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 Licencingin order to enable interoperability with Web-based applications for researchers.

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.
