The document discusses linked open data best practices for publishing, sharing, and interlinking structured data on the web. It highlights benefits for researchers, developers, librarians, and institutions, including improved data integration, reduced duplication of efforts, and the potential for greater discovery. The document also addresses challenges and the importance of open data while emphasizing that it enhances but does not replace the role of librarians in metadata creation.

1. Linked Open Data
best practices for publishing, sharing, and
interlinking structured data on the Web

2. Linked (Open) Data – what is it?

12. 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/

13. 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

14. 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

15. 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

16. 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

17. Available Linked Library Data

18. Available Linked Open Data (well, a subset)
http://lod-cloud.net/

19. 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

21. 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…
