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

What is OpenURL?

• A NISO standard enabling access to services for a referenced information resource.

• NISO OpenURL: http://library.caltech.edu/openurl/

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

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. <doi:10.1006/mthe.2000.0239>

– 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. <doi:10.1126/science.275.5304.1320> <pmid:9036860>

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

OpenURL Link Resolvers

• Essentially a database of resource service providers and how they organize their content

9

OpenURL Link Resolver Terminology & Illustration

• Refer to BOF wiki page at: http://bugs.sakaiproject.org/confluence/x/BUk

10

OpenURL Challenges

• Dirty/Insufficient data from sources

• Diverse and constantly changing targets

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

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?

Discussion topics

• Can we pressure vendors for better data?– Conforming to open standards?

• Can we skip the Menu?
