  1. DOI and CrossRef Richard O’Beirne Blackwell Publishing Seminar on Linking Technologies Edinburgh, 6 March 2001

  2. Blackwell Publishing • Blackwell Publishing (2001) Blackwell Science [STM] Munksgaard [Danish STM] Blackwell Publishers [Humanities, Social sciences] • Combined output 500+ journals 600 text and reference books p.a. • Publishes on behalf of 550 academic and professional societies • Online journals service: Synergy Also publish through 15+ aggregators and intermediaries

  3. Our involvement with CrossRef • One of twelve founder members • Represented on Board by John Strange • Represented on Technical Working Group and System Rewrite Group by Richard O’Beirne

  4. CrossRef organization • Publishers International Linking Association (PILA) - independent, not-for-profit, incorporated January 2000 • Board of Directors • AAAS (Science),Academic Press (Harcourt), AIP, ACM, Blackwell Science, Elsevier Science, IEEE, Kluwer, Nature, OUP, Springer, Wiley • Fees, member terms, technical infrastructure and standards established See http://www.crossref.org

  6. What is CrossRef? • A neutral, non-profit, independent membership organization • Members: publishers of original scholarly material • Users: publishers and any organization creating links to full text articles • No need for bilateral linking agreements • CrossRef System makes broad-based linking efficient and manageable

  7. CrossRef’s aims • Purpose 1: Enable persistent links from primary article references to the cited articles at other publishers’ sites • Purpose 2: Maximize links to full text articles from all information resources • Purpose 3: Enable links between all types of scholarly content (conference proceedings, books, encyclopedias, patents, etc)

  8. Current Status • 68 Member publishers (60% are non-profit) • Metadata deposited for 2.7 million articles from 6100 journals 2,735,247 records in CrossRef MDDB as of Mon Mar 5 00:52:20 EST 2001 • System went live in June 2000: thousands of journals with links (Elsevier, Academic Press, Wiley, Springer, Blackwell Science) • 3 million+ articles in 2001 • 0.5-1 million new articles per year

  9. Current Status: metadata depositors

  10. CrossRef System - Components • Persistent Identifiers • Digital Object Identifiers (DOIs)[http://www.doi.org] • Standardized Metadata • XML DTD[http://www.crossref.org] • Resolution System (to get from Identifiers to Content) • DOI/Handle System[http://www.handle.net]

  11. The Article Identifier • Digital Object Identifier (DOI) • unique, persistent, NISO standard • DOI System routes a DOI to a URL registered by publisher (and it can do a lot more besides…) • With a DOI - • linker doesn’t need to know publishers’ linking algorithms/systems • if a publisher changes their URLs (or a journal moves to another publisher), DOI-enabled links will still work • article is guaranteed to be online (only articles online get DOIs)

  12. DOI resolutions since CrossRef launch

  13. DOI • DOI Problem • how do you know what the DOI is for an article? • CrossRef provides a database of DOIs and a DOI Lookup service (telephone book and directory assistance)

  14. The CrossRef Process • Publishers deposit article metadata (including DOIs) in CrossRef database • Publishers query references from articles against CrossRef MDDB to lookup DOIs • Publishers use DOIs to create reference links in their online journals • Users click on reference links and go to other Publishers’ site

  15. CrossRef Metadata Admin Stuff DOI Batch ID - uniquely identifies batch Time Stamp - uniquely identifies batch Depositor - name and email for error messages Registrant - DOI Prefix owner Content Stuff DOI - for the DOI Directory URL - where the DOI resolves Article Title (optional) Author - first author last name Publication Date - electronic/print date Enumeration (volume, issue, page) Journal Title, ISSN/Code

  16. Metadata file example

  17. User Workflow for reference linking 3. Journal production systems export articles with DOIs Publisher Online Journal System Publisher Production System 2. DOI Lookup: a Journal production system requests a DOI based on citation metadata 4. Users may request and retrieve articles via DOI resolution system 1. Journal production systems export metadata to MDDB as new articles are published CrossRef MDDB

  18. DOI Resolution - IDF System Online Journal 1 1. User Gets Article 2. User Clicks DOI 3. URL Returned DOI Directory (Handle System) End User 4. User Gets Cited Article Online Journal 2

  19. Business Rules/Governance • CrossRef Membership • Provide full bibliographic citation for incoming DOI links (‘response page’) • many publishers will give free abstracts • information on acquiring article (pay online, document delivery, subscription) • Access to abstracts and full text controlled by publishers - business model neutral • CrossRef guarantees links

  20. CrossRef Fees • Principles • operate on a cost recovery basis • fees should be related to system usage • no charges to end users to click links • flexibility • Fees • Members: Annual Membership, Deposit, Retrieval (one-time for each DOI looked up) • Affiliates: Annual Admin Fee, Retrieval • See http://www.crossref.org

  21. Issues for the Future • Multiple Resolution • one DOI = one URL is starting point • multiple locations and multiple files • ‘Appropriate Copy’ Issue (a.k.a ‘Contextualization’) • Prototype with libraries (DLF, CNRI, IDF) • http://www.niso.org/CNRI-mtg.html • Access to “Non-subscribed” Content • Archive Repositories (JSTOR, ADS)

  22. Conclusion I • CrossRef is a milestone • Without CrossRef broad-based linking is not feasible (high costs, business issues and technical problems) • DOIs and Metadata lay the groundwork for more sophisticated linking (URLs don’t) • CrossRef is a vehicle for publishers to work with libraries and others

  23. Conclusion II • Publishers need: • excellent, easy-to-use CrossRef system • technical support and information • Users want: • lots of links (to content and services) • personalized/localized links • easy (not necessarily free) access to full text • More work to do…
