  2. Overview • Background – why focus on OpenURL quality • Current focus – what is the problem space being tackled by the working group • Status • Looking forward • Getting involved

  3. Background • Item-level linking became part of our vocabulary a decade ago as librarians worked to link users from the point of discovery to the content that was discovered. • OpenURL and link resolvers provide a scalable solution to item level linking. • Things don’t always work as well as they should… …this is the subject of a 2008 study led by Adam Chandler investigating issues with his institution’s link resolver. *Chandler, Adam. 2009. Results of L’Année philologique online OpenURL Quality Investigation: Mellon Planning Grant Final Report. http://metadata.library.cornell.edu/oq/files/200902%20lannee-mellonreport-openurlquality-final.pdf.

  12. Summary of possible problems:Current focus for iota • Structure -- Bad OpenURL • Completeness -- Data elements missing • Accuracy -- Data elements wrong

  13. IOTA Working Group • Improving OpenURL Through Analytics (iota) • Created in 2010 • Basic Assumptions: • Results are achieved through an analytical investigation of how OpenURL links work. • Practical: Address the links generated by the OpenURL standard, not the standard itself. • Selective changes to OpenURLs will lead to significant improvement in linking success rate. • Motto: "small changes. big improvements"

  14. Desired Outcomes • Develop community-recognized index for measuring the quality of OpenURL links generated by content providers. • Produce qualitative reports that will help OpenURL providers quickly compare their OpenURL quality to that of their peers. • Method: • fair; • transparent; • scalable across all OpenURLs and their providers.

  15. Focus • Core elements: • Contained in IOTA's OpenURL reporting system; • 9 million OpenURLs from libraries and providers.  • Scoring system based on assumption: • Correlation exists between • # of core elements ("OpenURL completeness") & • ability of OpenURLs to link to specific content. • Weighting assigned to core elements: • Based on relative importance • spage vs atitle • issn vs jtitle • doi/pmid vs date, etc.

  16. Work in Progress • Element weighting still in progress: • E.g., importance of identifiers (doi, pmid) vs bibliographic data (issn, volume, spage). • Currently, IOTA focuses on OpenURLs from citation sources only. OpenURL quality is also influenced by: • knowledge base, • resolver, • full-text provider (target). • High "completeness" score of OpenURLs not always indicative of "success" in linking to full texts • Combination of multiple indexes along linking nodes may provide more complete picture.

  17. Status • Project web site created • 9 million+ OpenURLs loaded • Initial set of reports available for analysis of data – publicly available • Work underway on creating a completeness index • Exploring options with KBART and other groups for looking at other aspects of OpenURL quality

  19. How can I get involved in IOTA? If you are a vendor -- • Look at IOTA data ... or... • Point your tech folks to our data • This data is meant to help make improvements in your openURL linking. If you are a librarian -- • Contribute data to IOTA • Help spread the word to vendors • More information on the IOTA project at:http://openurlquality.niso.org/
