7. Data and Web 2.0
How can data get enhanced by using it?
What can users create with the tools of the
library?
Will control and web 2.0 fit?
Let‘s take a look...
8. Wikipedia
free encyclopedia
not free as beer, free as
speech
about 700.000 Article in
German-lang. Wikipedia
aprox. 175.000 about
Persons (25 %)

between in 8 languages
11. Way of the Cooperation

16. Results of the Cooperation
Over 38.000 link articles
A lot correction wishes for the PND
Wikipedia a good starting point for a search
Wikipedia users can very easy become library users
17. Other Authority Files and Wikipedia
GKD: Institutions
100 links
finding the ID is very hard / no retrieval webservice (now)
Complicated structure
18. Other Authority Files and
Wikipedia
SWD: Keywords
Already over 250 links
finding the ID is very hard / no retrieval webservice now
Czech Names Authority Files
about 800 Links
19. Further Ideas
Links from the catalog to wikipedia
linking of other authority files
Links from Wikipedia to other resources (via
Linkresolver)
20. Classification of Wikipedia
via Social Tagging = categories
Thoughts about classification with:
DDC (not free!)
RVK (only uses in Germany )
Basisclassification
UDC (not free, too)
Vision: A free classification for the net
21. Wikipedia:
An Authority File for the net?
very often linked
One theme - one article eg. Wiki
every wikipedia-link index an document with a theme
article in every language has a persistent URL
open for use in every context
22. Authority Files and Web 2.0
Authority files can have a role in the web 2.0
there must be an open interface/ service for retrieval
everything that is indexed on the net with authority files
can be easy integrated in a federated search
O‘Reilly: You have to found ways that your data get more
important that more it will be used
