About the Webinar

Link resolvers have become an important element of providing access to full-text electronic content and are now ubiquitous in both the library and publishing community. These systems work well enough a majority of the time. However, they are not entirely problem free, and as a result users may not always obtain access to information which their institutions have licensed for them. The management of the large volumes of linking data necessary to support these services is a problem in scale as well as in detail. Several NISO projects have sought to improve the reliability of these systems, including the Knowledgebases and Related Tools (KBART) and Improving OpenURL through Analytics (IOTA) initiatives.

This webinar will highlight these NISO projects and other community initiatives launched to create community-managed knowledge base repositories.

  24. 24. KBART Working Group Knowledge Bases And Related Tools
  25. 25. Metadata Supply Chain Knowledgebase: Holdings information used by an OpenURL link resolver
  26. 26. Metadata Supply Chain The supply chain of metadata between content providers (publishers) and knowledgebases
  27. 27. The Problem If the holdings information in the knowledgebase is outdated/incorrect, it impacts the OpenURL link resolver and all systems reliant upon it (discovery services, OPAC, ILL, etc.)
  28. 28. KBART Background Who – Publishers, Aggregators, KB vendors, Libraries What – Universal holdings metadata format to improve the OpenURL Knowledgebase metadata supply chain Where – NISO KBART Workroom http://www.niso.org/workrooms/kbart When – Phase I – Released Jan 2010 Endorsement of Phase I – Began June 2010 Phase II - Released April 7, 2014 *Supercedes KBART Phase I* Why – Better access for users through accurate holdings data
  29. 29. Who is behind KBART II  Standards organizations  UKSG and NISO  Working group members (stakeholders):  Knowledgebase vendors ExLibris, OCLC, Serials Solutions, EBSCO  Content Provider (Publisher & Aggregators) ASP, AIP, Royal Society Publishing, Springer  Subscription Agents  Libraries & Consortia  Full list –http://www.niso.org/workrooms/kbart/phase2roster/

  31. 31. Original Phase I Fields (16)
  32. 32. Updating the Rec’s  Spreading the word and outreach  Working with content providers, vendors, etc.  Soliciting broad feedback (all feedback included in Phase II Recommendations)  Focus on 3 new areas
  33. 33. 3 Areas of Emphasis  Freely available content  Ebooks & Conference Proceedings  Consortial Holdings  9 new fields (for a total of 25) & applicable new guidelines
  34. 34. Free Content: New Field  1 new field, 1 modification to existing field  New “access_type” field  Type can be “F,” for free content, or “P” for paid content (is aligned with OAMI rec’s thus far)  Free text describing details may be entered into existing “coverage_notes” field.
  35. 35. Free Content Issues  KBART is not endorsing any particular Open Access model • For “F” to be used, 100% of title’s content must be freely available  Difficulty with hybrid titles (author pays OA, embargoes, rolling access walls, etc.)  Needs to be addressed at the article-level
  36. 36. Ebooks & Conference Proceedings, Part 1  8 new fields total  1 new field applies to differentiate formats  New “publication_type” field  Type can be “monograph,” “journal,” or “conference proceeding”
  37. 37. Ebooks & Conference Proceedings, Part 2 Field Description publication_type Serial (i.e., journals and conference proceeding series) or monograph (i.e., book, eBook, conference proceeding volume) date_monograph_published_print Date of monograph first published in print date_monograph_published_online Date of monograph first published online monograph_volume Number of volume for monograph (applicable to eBooks and conference proceedings; for proceedings, volume within the conference proceedings series) monograph_edition Edition for book first_editor First editor (for monographs, i.e., ebooks or conference proceedings volumes) parent_publication_title_id Title ID of parent publication (for a conference proceeding volume, its parent_publication_title_id is the title_id of the conference proceedings series) preceding_publication_title_id Title ID of preceding publication title, for journal serials and conference proceeding serials.
  38. 38. Ebook & Conference Proceedings: Issues  Some existing fields already apply to monographs and serials (e.g. identifier fields for ISSN/ISBN)  Some new fields are used for certain formats (e.g. “monograph_edition”)  “preceeding_publication_title_ID” can be problematic
  39. 39. Consortial Holdings  Librarians & consortium managers really wanted this (and more)!  Lack of readily available consortium lists  No new fields for this area specifically, rather, new guidelines
  40. 40. Consortial Holdings: Guidelines  Will require separate lists under 2 circumstances: 1) Package consists of unique titles -or- 2) Package consists of unique coverage dates
  41. 41. Consortial Holdings: File naming conventions “[ProviderName]_[Region/Consortium]_[PackageName] _[YYYY-MM-DD].txt”  Global lists (i.e. universal list) Ex:JSTOR_Global_AllTitles_2013-01-14.txt  Consortium specific lists Ex: Oxford_SCELC_AllTitles_2013-01-09.txt  Region specific lists Ex: Springer_Asia-Pacific_Medicine_2013-01-28.txt

  44. 44. Useful Resources to Google  NISO KBART Workroom  KBART Phase I Final Report  KBART Phase II Final Report (RP-9-2014)  KBART Registry  Link Resolvers and the Information Supply Chain
  45. 45. What we learned about OpenURL in NISO’s IOTA Initiative NISO Webinar: Getting to the Right Content: Link Resolvers and Knowledgebases May 14, 2014 Adam Chandler, Cornell University
  46. 46. What was IOTA? 2010-2013 NISO Working Group that measured the relative importance of the elements that make up OpenURL links to help vendors improve their OpenURL strings so that the maximum number of OpenURL requests resolve to a correct record.
  47. 47. Before OpenURL: Proprietary Linking • Certain A&I database providers (e.g., CSA, PubMed) offered full-text linking options for a select number of content providers. • Libraries manually activated full-text linking with providers they had subscriptions with.
  48. 48. Proprietary Linking: Pros and Cons
  49. 49. Proprietary Linking: Pros and Cons • Linking had to be activated manually by libraries for each full-text provider. • A&I providers offering this option were few. • Selection of full-text providers was limited. Cons:
  50. 50. Proprietary Linking: Pros and Cons • Linking had to be activated manually by libraries for each full-text provider. • A&I providers offering this option were few. • Selection of full-text providers was limited. • Once set up, the static links to full texts were accurate. • Debugging is easy: A&I --> Full Text Pros: Cons:
  51. 51. Advent of OpenURL Objective: Deliver full texts unrestrained by proprietary silos. • Open standard generating dynamic links at time of request. Knowledge base (KB) with library's holdings. • Replaces librarian as intermediary in linking. • Indicates provider of "appropriate copy" Solution: A&I ("Source") --> A-Z list ("KB") --> Full Text ("Target")

  54. 54. Pros & Cons of Dynamic Reference Linking
  55. 55. Pros & Cons of Dynamic Reference Linking Pros: • KB/Resolver vendors took over most of the linking setup: Less work for libraries and providers. • Dynamic reference linking scales better. Participation by A&I platforms and full-text providers grew faster than proprietary linking.
  56. 56. Pros & Cons of Dynamic Reference Linking Pros: • KB/Resolver vendors took over most of the linking setup: Less work for libraries and providers. • Dynamic reference linking scales better. Participation by A&I platforms and full-text providers grew faster than proprietary linking. Cons: • Dynamic linking less predictable than static linking: debugging is very hard and does not scale. • No systematic method exists to benchmark linking, and thus, dynamic reference linking has not improved significantly since version 0.1 of the standard.
  57. 57. Identifying source of problem… "72% of respondents to the online survey either agreed or strongly agreed that a significant problem for link resolvers is the generation of incomplete or inaccurate OpenURLs by databases (for example, A&I products)." Culling, James. 2007. Link Resolvers and the Serials Supply Chain: Final Project Report for UKSG, p.33. http://www.uksg.org/sites/uksg.org/files/uksg_link_resolvers_final_report.pdf.

Defining methodology for approaching problem Researchers have indicated the need for metadata quality metrics, including: completeness; accuracy; conformance to expectations; logical consistency and coherence. Bruce, Thomas R. and Hillmann, Diane I. 2004. The Continuum of Metadata Quality: Defining, Expressing, Exploiting. In Metadata in Practice. Ed. Diane I. Hillmann and Elaine L. Westbrooks. Chicago: American Library Association, pp. 238-256.
  59. 59. IOTA & KBART: complementary NISO working groups IOTA • Deals with issues specific to OpenURL linking; • Seeks improvements in OpenURL elements used by: –OpenURL providers.
  60. 60. IOTA & KBART: complementary NISO working groups IOTA • Deals with issues specific to OpenURL linking; • Seeks improvements in OpenURL elements used by: –OpenURL providers. KBART • “Knowledge Bases And Related Tools” • Deals with data issues at the KB level • Seeks improvements in data exchange practices between: –content providers (e.g. OpenURL providers); –product vendors (e.g. link resolver vendors). –subscription agents;
  61. 61. IOTA’s Basic Assumptions • Results achieved through an analytical investigation of how OpenURL links work. • Practical: Not the OpenURL standard that was addressed, but links (OpenURLs) generated by standard. • Selective changes to OpenURLs will lead to significant improvement in linking success rate. "small changes. big improvements"
  62. 62. (A) Usefulness of comparing OpenURLs • Content providers that generate OpenURLs can: –compare their OpenURLs with other providers; –make improvements to their OpenURLs. • Institutions can: –compare OpenURL providers; –make local adjustments to OpenURL setup. • Resolver vendors can: –compare OpenURL providers; –Change their settings for OpenURL providers: –Link resolvers; –Web-scale discovery products.
  63. 63. http://openurlquality.org/
  64. 64. Report types • Source reports –Viewing how a particular (1) vendor or (2) database –A. uses OpenURL elements (element frequency) –B. formats OpenURL elements (pattern frequency) • Element / Pattern reports –Viewing how a particular (1) element or format –A. is used across vendors –B. is used across databases
  65. 65. Report types • Source reports –Viewing how a particular (1) vendor or (2) database –A. uses OpenURL elements (element frequency) –B. formats OpenURL elements (pattern frequency) • Element / Pattern reports –Viewing how a particular (1) element or format –A. is used across vendors –B. is used across databases • Vendor Quality Report? –Viewing vendors’ OpenURL quality score
  66. 66. (B) OpenURL Quality Index: Rating vendors by their OpenURLs 1. Core Elements: •Any element contained in IOTA's OpenURL reporting system; •27M OpenURLs obtained from libraries & content providers. 2. Scoring System: •Assumption: Correlation exists between •# of core elements ("OpenURL completeness") & ability of OpenURLs to link to specific content. 3. Element Weighting: •Assigned based on their relative importance: •spage vs atitle •issn vs jtitle •doi/pmid vs date, etc.
  67. 67. Further investigation was needed
  68. 68. Further investigation was needed • Element weighting needed to be adjusted in a more systematic way:
  69. 69. Further investigation was needed • Element weighting needed to be adjusted in a more systematic way: • Importance of identifiers (doi, pmid) vs bibliographic data (issn, volume, spage, etc.) • Relative importance of bib. data (issn vs volume vs spage, etc.)
  70. 70. Further investigation was needed • Element weighting needed to be adjusted in a more systematic way: • Importance of identifiers (doi, pmid) vs bibliographic data (issn, volume, spage, etc.) • Relative importance of bib. data (issn vs volume vs spage, etc.) • IOTA focused on OpenURLs from citation sources only. How is OpenURL linking impacted by other factors?
  71. 71. Further investigation was needed • Element weighting needed to be adjusted in a more systematic way: • Importance of identifiers (doi, pmid) vs bibliographic data (issn, volume, spage, etc.) • Relative importance of bib. data (issn vs volume vs spage, etc.) • IOTA focused on OpenURLs from citation sources only. How is OpenURL linking impacted by other factors? • knowledge base, • resolver, • full-text provider (target).
  72. 72. http://www.niso.org/publications/tr/
  73. 73. It is impossible to give each OpenURL element a universal weight. Therefore, an industry wide OpenURL quality index is impossible.
