THE PROBLEM SPACE

• Kbs were primarily used for access

• They became a part of the add-on ERMS

• Movement toward integrated systems

• A positive and necessary experience.

The Kb experime

THE PROBLEM SPACE

• Kbs are needed for management too

• Identifiers are crucial

• We need to manage all e-resources

• Systems should be integrated and Kb-centric

Lessons learned

Managing the right “thing”

Going beyond bibliographic description

Creating identifiers for what we need to manage

WHY KB-CENTRIC?

Title: Tetrahedron Letters

Format: Electronic

Publisher: Elsevier

Package: Freedom Collection

Enhanced data means we can manage what’s important

Open data means that the knowledgebase is not wedded to any one system

Community-managed data means we contribute directly to the quality of the knowledgebase

HOW CAN GOKB HELP?

ENHANCED DATA: THE TIPP

KBART Phase II: Ensuring Access with Accurate Metadata

Chad Hutchens

Head of Digital Collections

University of Wyoming Libraries

KBART Working Group

KnowledgeBases And Related Tools

Metadata Supply Chain

Knowledgebase: Holdings information used by an OpenURL link resolver

Metadata Supply Chain

The supply chain of metadata between content providers (publishers) and knowledgebases

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If the holdings information in the knowledgebase is outdated/incorrect, it impacts the OpenURL link resolver and all systems reliant upon it (discovery services, OPAC, ILL, etc.)

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 2010Endorsement of Phase I – Began June 2010Phase II - Released April 7, 2014 *Supercedes KBART Phase I*

Why – Better access for users through accurate holdings data

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

Original Phase I Fields (16)

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

3 Areas of Emphasis

Freely available content

Ebooks & Conference Proceedings

Consortial Holdings

9 new fields (for a total of 25) & applicable new guidelines

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.

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

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”

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.

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

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

Consortial Holdings: Guidelines

Will require separate lists under 2 circumstances:

1) Package consists of unique titles-or-

2) Package consists of unique coverage dates

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

How we got to Phase II

Draft of KBART Phase II released Oct, 2013 for public comment period

Received 45+ comments Group met and discussed each individually Nettie, Chad, Magaly spend holidays drafting

responses and making changes to rec’s ;) D2D Committee approves Phase II, April 7,

Link Resolvers and the Information Supply Chain

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

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.

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.

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:


• 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:

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")

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.


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.

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)."

IOTA & KBART: complementary NISO working groups

IOTA

• Deals with issues specific to OpenURL linking;

• Seeks improvements in OpenURL elements used by:

– OpenURL providers.

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;

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"

(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.

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

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

(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.

Further investigation was needed


• Element weighting needed to be adjusted in a more systematic way:


• 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.)




spage, etc.)

• IOTA focused on OpenURLs from citation sources only. How is OpenURL linking impacted by other factors?




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).

http://www.niso.org/publications/tr/

It is impossible to give each OpenURL element a universal weight.

Therefore, an industry wide OpenURL quality index is impossible.
