1. Accessing scholarly resources in Sakai using OpenURL Gaurav Bhatnagar The Sakaibrary Project 1 June 2006

2. 2 Objectives Get to know one another Share information pertaining to: –OpenURL (0.1 vs. 1.0) –OpenURL Link Resolvers –Sakaibrary and OpenURL Discuss issues regarding the use of OpenURL in Sakai

3. 3 What is OpenURL? A NISO standard enabling access to services for a referenced information resource. NISO OpenURL: http://library.caltech.edu/openurl/

4. 4 OpenURL Query Examples OpenURL 0.1OpenURL 1.0 (SAP1) http://www.example.com/resolver? url_ver=Z39.88-2004 &url_ctx_fmt=info:ofi/fmt:kev:mtx:ctx sid=myid:mydb&rfr_id=info:sid/myid.com:mydb &rft_val_fmt=info:ofi/fmt:kev:mtx:journal &genre=article&rft.genre=article &atitle=p27-p16 Chimera: A Superior Antiproliferative &rft.atitle=p27-p16 Chimera: A Superior Antiproliferative &title=Molecular Theory&rft.jtitle=Molecular Theory &aulast=McArthur&rft.aulast=McArthur &aufirst=James&rft.aufirst=James &date=2001&rft.date=2001 &volume=3&rft.volume=3 &issue=1&rft.issue=1 &spage=8&rft.spage=8 &epage=13&rft.epage=13 Hybrid OpenURL

5. 5 OpenURL 1.0 vs. OpenURL 0.1 OpenURL 1.0 is an abstraction on top of OpenURL 0.1 OpenURL 1.0 “drops” the OpenURL moniker OpenURL 1.0 introduces the ContextObject Wrapper to encapsulate the OpenURL 0.1

6. 6 ContextObject Example scenario: –Jane Doe, a Caltech student with e-mail address jane.doe@caltech.edu, reads the following electronic scholarly article in the Elsevier ScienceDirect® collection: McArthur, James G. et al. 2001. p27-p16 Chimera: A Superior Antiproliferative for the Prevention of Neointimal Hyperplasia. Molecular Therapy. 3(1) 8-13. –In the reference list of that article, she comes across a reference to the following article: Bergelson, J. 1997. Isolation of a common receptor for coxsackie B viruses and adenoviruses 2 and 5. Science. (275) 1320-1323.

7. 7 Defining a ContextObject Community Profiles –Level 1, 2 San Antonio Community Profiles (SAP1, SAP2) Namespaces Metadata Formats OpenURL Registry: –http://alcme.oclc.org/openurl/servlet/OAIHandler?verb=ListSets

8. 8 OpenURL Link Resolvers Essentially a database of resource service providers and how they organize their content

9. 9 OpenURL Link Resolver Terminology & Illustration Refer to BOF wiki page at: http://bugs.sakaiproject.org/confluence/x/BUk

10. 10 OpenURL Challenges Dirty/Insufficient data from sources Diverse and constantly changing targets

11. 11 The Sakaibrary Project A project to build open-source tools to enable access to licensed digital content within Sakai One end goal: link to full text of Citations stored in Sakai OpenURLs need to be built and a linking workflow needs to be established

12. 12 Sakaibrary Link Resolver Survey What link resolvers are in use? What kinds of services are provided? What metasearch engines are used in combination with link resolvers?

13. 13 Sakaibrary Link Resolver Survey Results Refer to BOF wiki page at: http://bugs.sakaiproject.org/confluence/x/OUk

14. 14 Discussion topics Can we pressure vendors for better data? –Conforming to open standards? Can we skip the Menu?
