This presentation discusses the SFX Framework, designed to enhance context-sensitive reference linking in digital libraries. Key issues include how to connect standard citations to their respective resources, provide appropriate services, and navigate bibliographic metadata effectively. The framework leverages OpenURL technology for dynamic and context-aware linking of resources, tailored to user access rights. By implementing these techniques, libraries can improve user experience and facilitate access to full text and other related services, ensuring efficient information retrieval.

  1. The SFX Framework for Context-Sensitive Reference Linking herbert van de sompel ICOLC Meeting, Orlando April 13th 2000 acknowledgements patrick hochstenbach the LWW team of the LANL Research Library the Council on Library and Information Resources the Digital Library Federation the Belgian National Science Foundation American Physical Society ; Ex Libris ; SilverPlatter ; Wiley

  2. generic reference linking problem given : the information in a standard citation how : does one get to the thing to which the citation refers?

  3. Full text

  4. the extended services problem given : the information in a standard citation bibliographic metadata how : does one get to the thing to which the citation refers? does one create relevant services for it?

  5. citation databases Full text Ulrich’s PubMed

  6. Who is Who Books in Print Amazon.com

  7. citation databases Ulrich’s Full text Medline

  8. the appropriate copy problem given : the information in a citation to a journal article how : how does a user get to an appropriate copy of the article

  9. appropriate full text

  10. the context-sensitive services problem given : the information in a citation to a journal article bibliographic metadata how : how does a user get to an appropriate copy of the article does a user get appropriate services for it?

  13. OpenURL a. b. allow parsing server metadata server deliver linking server link-source context-sensitive extended services

  14. openURL OPAC FTXT FTXT A&I institutional service component openURL openURL openURL SFX context-sensitive linking

  15. :- server allow context-sensitive services search ) I allow result OpenURL

  16. allow context-sensitive services 1. CookiePusher, DLF certificate, ... 1. implement a technique to make the system understand the difference between a user that has access to a service component and one that does not

  17. allow context-sensitive services 2. for users with access to a service component, provide an OpenURL for each metadata-object 2. OpenURL: target = service component content = elements of the metadata, in a public syntax

  18. OpenURL examples SFX server = http://sfx.aaa.edu/menu record = AU Smith, Paul ISSN 1234-5678 VOLUME 12 ISSUE 3 PAGES 1-8 PY 1998 DBASE ERL-BIOSIS DBASE-AN 987641

  22. parsing server metadata service component deliver linking server deliver context-sensitive services

  23. search ) I allow result OpenURL :- server fetch DOI-X SFX parsing server bring the metadata for which services are requested to the SFX linking server )

  24. SFX parsing server 1. read the OpenURL • 2. collect object-metadata: • from the OpenURL • via fetch from resource 3. augment object-metadata

  25. extended services metadata metadata SFX linking server given the metadata & given the digital library collection, which services are relevant? evaluate metadata

  26. SFX linking server • a fully dynamic approach • no pre-computation • on-the-fly decision making about relevance of services • on-the-fly creation of service “links”

  27. SFX linking server definition of potential services information about the local collection rules supporting a decision on the relevance of services
