DESCRIPTION
Antoine Isaac, R&D Manager, Europeana gives presentation on Linked Open Data. The General Assembly (GA) is EIFL’s annual knowledge sharing and networking event for library professionals in developing and transition countries. Each year EIFL brings together national coordinators from over 40 countries to debate the latest developments in electronic content delivery, to discover emerging issues of significance to libraries, and to share achievements from library consortia over the last year.

interlinking structured data on the Web

Linked (Open) Data – what is it?
http://data.bnf.fr/ark:/12148/cb13506631t
Data on the web, for machines

Typed links for machines

General benefits of linked data
Structured data
URIs and links, not just strings
Good for internationalization
Shareable data
Fits and completes open data strategies
Extensible and mashable
"Open world" - anybody can add descriptive information and annotations
about the same thing
Standard protocols/techniques
http://www.w3.org/2005/Incubator/lld/XGR-lld/
Benefits to researchers, students and
patrons
Information seekers can extract and re-mix the parts of the data they
need, add own annotations
Library items and data can be fully integrated into research documents
and bibliographies
Greater discovery and use, across library and non-library resources
Benefits to developers
Use of standard protocols and models
Web-based identifiers makes resources immediately
available and up-to-date
Freely mix or mash-up data from libraries with other sources
Benefits to librarians, archivists,
curators and their institutions
Pull together data from outside their direct environment
Concentrate on their domain of local expertise rather than
re-creating existing descriptions
Less duplication of effort, lower infrastructure costs
Available Linked Library Data
http://www.w3.org/2005/Incubator/lld/XGR-lld-vocabdataset/
Benefits to librarians, archivists,
curators and their institutions
Use of mainstream technologies rather than systems
specific to libraries
Clarification of metadata licensing
Greater visibility on the web and reuse
Challenges and opportunities
Vision works better if data is Open
Some parts of the technology still in maturation
Adaptation to business processes still in progress
Full potential not reached yet
It does not replace librarian work of creating metadata!
But it makes it better focused and more valuable…
Thank you!

Linked (Open) Data – what is it?

Linked Data?
1. Use URIs as names for things
2. Use HTTP URIs so that people can look up those names
3. When someone looks up a URI, provide useful
information using standards (RDF, SPARQL)
4. Include links to other URIs, so that they can discover
more things
Tim Berners-Lee,
http://linkeddata.org/
Leading to HTML page for humans
Leading to data for software agents
Also contextual resources
Contextual resources lead to data too
AAT Concept – RDF
http://vocab.getty.edy/aat/300198626
Not just AAT
Getty will release other vocabularies as linked data
Our partner projects use other linked data sets
Geonames, VIAF, GND, Iconclass, DBpedia, MIMO, PartagePlus
Different semantic grains
Semantic Web principle of specializing
classes and properties
Enables extensions, “applications
profiles”, based on needs and best
practices from specific sectors or
domains
