1 Eric Hellman Founder, President Openly Informatics,Inc. Bloomfield, New Jersey OpenURL and Linking in Libraries: Distributed AND REIntegrated Information Systems

2 Outline What is OpenURL? What is a Link Server? Demo and Technology Discussion

3 What is OpenURL??? OpenURL is an internet equivalent of the index card in the (paper-based) card catalog –Packages bibliographic data –Can be presented to internet services – NISO Standard

4 What is a Link-Server??? A Link-Server is an internet equivalent of a help desk in the (paper-based) library –Present it with bibliographic data or a query –It helps you locate the best information in the library –Standards-based - many product options; –1Cate, SFX, LinkFinderPlus, ArticleLinker, LinkSource, LinkSolver… –now widely deployed >1,000 libraries

5 Full text DBs Full text DBs EBSCO Google Scholar Google Scholar ISI OPAC A&I service A&I service Journal Publishers Journal Publishers PubMed An internet library is built by librarians using electronic resources from many vendors

6 Full text DBs Full text DBs EBSCO Google Scholar Google Scholar ISI OPAC A&I service A&I service Journal Publishers Journal Publishers PubMed Some services offer links to a few resources User

7 Full text DBs Full text DBs EBSCO Google Scholar Google Scholar ISI OPAC A&I service A&I service Journal Publishers Journal Publishers PubMed User Other services offer links to different resources

8 EBSCO Google Scholar Google Scholar ISI OPAC A&I service A&I service Journal Publishers Journal Publishers PubMed Linking is inconsistent and hard to manage Full text DBs Full text DBs

9 Users are confused Who is EBSCO? What is a DOI? Why doesn't my bookmark work?

10 Full text DBs Full text DBs EBSCO Google Scholar Google Scholar ISI OPAC A&I service A&I service Journal Publisher Journal Publisher PubMed A link server introduces consistent and comprehensive linking throughout the library 1Cate

11 Full text DBs Full text DBs EBSCO Google ISI OPAC A&I service A&I service Journal Publishers Journal Publishers ingenta User 1Cate Users see a Library, not a bunch of databases and a linking brand The Library

12 How URL’s fail User's library doesn't subscribe to target target authenticates by IP, user is off campus User's library gets target item in a full-text aggregation User's library has a locally hosted copy of target journal User's country has a nationally hosted copy of target journal target has moved its content without telling source target has become a porn site This is known as the "Appropriate Copy Problem" URL source target User

13 Full text DBs Full text DBs EBSCO Google ISI OPAC A&I service A&I service Journal Publishers Journal Publishers ingenta User A A Library subscribes Pay per view $$$  The link server lets the library fix these problems and determine which copy is appropriate

14 Demo: search in Google Scholar

15 Demo: clark university 1Cate

16 Demo: fulltext at Infotrac

17 Demo: azabu university

18 OpenURL: More than Full Text Links to OPAC for author, title Links to Google or Pubmed for article title Links to Amazon or Book in Print for ISBN, book author Links to Document Delivery or ILL for titles not found Links to patent and dissertation databases

19 OpenURL: low barrier resolver ? referent inserted by the information provider the thing the link is about

20 OpenURL: high function ? genre=article & issn= & volume=433 & issue=3 & date= & spage=364 & sid=EHOST:bbio & title=Journal+of+Comparative+Neurology & atitle=Hypoglossal+and+reticular+interneurons+involved+in+oro%2Dfacial+coordination+in+the+rat%2E resolver ? Referent, Referrer inserted by the information provider the thing the link is about can also include context information

21 OpenURL 1.0 : NISO standard rft_fmt=info:ori/kev:mtx:jarticle & rft.genre=article & rft.issn= & rft.volume=433 & rft.issue=3 & rft.date= & spage=364 & rfr_id=info:sid/ebsco.com:bbio & rft.title=Journal+of+Comparative+Neurology & rft.atitle=Hypoglossal+and+reticular+interneurons+involved+in+oro%2Dfacial+coordination+in+the+rat%2E resolver ? version & ContextObject ContextObject= Referent Referrer ReferringEntity ServiceType Requester Resolver

22 OpenURL: implemention Server side Select baseURL from institutional/customer profile Client side - OpenURL COinS - new convention for embedding metadata in HTML Usable by non-subscription services: blogs static web pages free access publications pay-per-view content semantic web spiders Used by most OpenURL-enabled databases Network-based central-site link redirectors Crossref link redirector/resolver used by majority of STM journal publishers

23 Sources and Targets FirstSearch, Infotrac, EBSCO, Proquest, SilverPlatter, CSA, Science Direct, Dialog, ABC-Clio, RLG, Web Of Science, OPACs, HW Wilson, ChemPort, EI, NISC, MathSciNet, Ingenta, SwetsWise, MetaPress, PubMed, Ovid, PubMed, Google Scholar. Linking web services- Crossref, EBSCO, Amazon, Google URL services 900 different types of generated links Sources (inbound OpenURL) Targets (outbound)

24 What is ? Where is J. Mol. Biol. 249, p.239 ? CrossRef !

25 Adding Metadata Formats in OpenURL 1.0: Linking to Slugs ctx_val_fmt=http://eusidic.org/organism& rft.genus=Ariolimax&rft.species=columbianus Zoological Record (Ovid) Article mentioning the banana slug (source) OpenURL Zoological Record (CSA) Zoological Record (Dialog) Zoological Record (NISC) SlugsRUs ? Genome databases

26 the Future of OpenURL Full NISO 1.0 compliance in production –See our NISO OpenURL test suite google:"OpenURL test suite" New domains- stocks, species, legal, music,... New applications- usage and collection metrics… New expressions- xml, rdf,... New services- learning objects, distributed reference… OpenURL 1.0 is the glue for the internet library
