  1. 1. OpenURL @ Rice Rafal Kasprowski Fondren Library October 21 & 23, 2008
  2. 2. Implementation Examples
  3. 3. Implementation Examples
  4. 4. Implementation Examples
  5. 5. Implementation Overview Source Target Full Text Resource that has: - no full texts e.g.: index, A&I database - only some full texts e.g.: aggregator database Resource Rice has full text sub for: - publisher journal - aggregator - complete or partial full text access
  6. 6. Linking from Source to Target • Information is sent from Source to Target as part of URL addresses. • But how is that possible given that URLs are so different from one provider to another? &_rdoc=1&_fmt=&_orig=search&_sort=d&view=c&_acct=C000049490&_version=1&_urlVersion=0 &_userid=963248&md5=245e64be6efdc7efdb4392784cb4d017
  7. 7. Non-standard Links v. OpenURL Standard • Most URLs do not share the same structure; information providers use proprietary links: E.g.: EBSCOhost ≠ Elsevier ≠ ProQuest • OpenURL offers a standard open URL structure that information providers can share. • OpenURL-compliant information providers can exchange bibliographic data by following the OpenURL standard.
  8. 8. What OpenURL Does • Defines linking parameters: OpenURL 0.1 Parameters Definition atitle Article / Chapter Title aulast First Author’s Family Name date Publication Date genre Item Bundle (e.g.: journal, book, etc.) or Individual Item (e.g.: article, proceeding, etc.) isbn ISBN issn ISSN issue Journal Issue jtitle Journal Title spage , epage Start Page, End Page title Publication Title volume Publication Volume id (id=doi:DOI) Unique Identifier (Document Object Identifier)
  9. 9. What OpenURL Does • Structures URL data… – OpenURL-compliant base: link up to “?” • • – Parameters and syntax elements (&, =) • issn=1079-0713&volume=155&spage=525&aulast=Winters&date=2004-11-01 • genre=article&issn=1040-8398&volume=48&issue=9&spage=799&epage=823 • id=doi:10.1016/1352-2310(95)00448-3 • … into functional links: • &volume=155&spage=525&aulast=Winters&date=2004-11-01 • &volume=48&issue=9&spage=799&epage=823 • 1352-2310(95)00448-3

  11. 11. OpenURL Standard - Summary Linking Aspect OpenURL Standard Involvement OpenURL Effectiveness Parameter Nomenclature •OpenURL compliance requires all participants use same parameter names (e.g.: date field is always referred to as date, article/chapter title as atitle, etc.), and pass the same info in these data fields (e.g.: date will never contain journal title). Parameter Use •OpenURL does not standardize compulsory parameter use, valid or conflicting parameter combinations, parameter precedence rules. •Information providers may not index some bibliographic information (e.g.: date, issue) and will therefore not be able to exchange it. •Sources should use as many parameters as possible to increase chances of match with Targets. Data Formats •OpenURL does not standardize format of data sent with parameters. Sources and targets may follow different accent standards and punctuation for atitle or format for date (YYYY v. YYYY-MM-DD) .
  12. 12. OpenURL Limitations • OpenURL provides syntax standard, but not indexing standard. – Journal column may be indexed as a whole (Source) or constituent articles could be indexed instead (Target), e.g.: • ESBCOhost Source may index “Latest Science News” column title, but • ProQuest Target may index each news item instead: “New species discovered”, “Pluto is a planet after all”, “Information not lost in black holes”.
  13. 13. OpenURL Limitations • OpenURL cannot account for all content – E.g.: Aggregators may not have all articles from an issue within our holdings, and OpenURL will create an incorrect link in this case. • OpenURL is not a workflow standard for information providers – E.g.: For recent articles, record may exist in Source (and even in Target), but full text is not necessarily loaded in Target yet.
  14. 14. OpenURL Limitations • Source OpenURL normally enabled via IP address – Accessible within Rice network (onsite, proxy, VPN) • Source OpenURL enabled via specific URL: – Accessible via Rice URL only – Not accessible directly via information provider or link from other site – E.g.: PubMed • Rice URL: otool=txriceflib • Non-Rice URL (PubMed, other provider’s site):
  15. 15. OpenURL Limitations • Source OpenURL enabled in Preferences (e.g.: Scirus): – Not accessible via other sites if cookie is missing on computer
