Linked (Open) Data – what is it?

Data on the web, 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
Modeling, linked data style
Cross-community re-use of data models
Models that re-use existing models
Semantic Web technology allows mixing them!
Collaborative, softer form of standardization
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!
