The document discusses the future importance of bibliographic data and sharing and control in Web 2.0. It argues that bibliographic data created by libraries is valuable and should be shared openly to allow users to enhance and reuse the data. The document proposes using open web standards like COinS and microformats to share bibliographic metadata and link authority files to resources on the web. It advocates for open licensing of bibliographic data and authority files to allow their reuse on the web.

6. Bibliographic data
created by the libraries
controled data
„product“ by the library

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 %)

9. Metadata for Persons
created in 2005
for the German Wikipedia DVD Project of Directmedia
done by the community with a half automatic tool
between in 8 languages

10. Metadata

11. Way of the Cooperation
Search after Persons
Wikipedia-
Persondata-Tool
full PND-Data
Online-Catalog
of Deutsche
Entry of the PND-Number
Nationalbibliothek
Wikipedia
Person-article
Link

12. Technical Realization

14. Article Source

15. Article

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

23. Sharing
The Browser is the Bridge

24. Sharing Data at Libraries
Z39.50
SRU/W

25. New Forms (Browser-based)
COinS
Microformats

26. COinS
Context Object in Spans
A Convention to Embed Bibliographic Metadata in
HTML
HTML span element with class attribute set to quot;Z3988quot;
http://ocoins.info

33. Wordpress and Coins
There is a plug-in:
just install it
the rest is done automatically

35. COinS in Weblogs

36. Microformats
web-based data formatting approach
re-use existing content as metadata
using XHTML and HTML classes / attributes
human readable
automatically processable by software
