  2. 2. ` linking out your references is the opposite of Cited By linking
  3. 3. • Members MUST add outbound CrossRef DOI links to their references – This is a membership rule Linking References
  4. 4. `
  5. 5. Getting back your matched references https://doi.crossref.org/getResolvedRefs?doi=10.1103/PhysRevE.91.062714&usr=…
  6. 6. ` Cited-BY (what other journals reference or ‘cite’ your journal)
  7. 7. Title of Presentation Presenter Presenter position @twittername Meeting/Conference title, Location, Date

  9. 9. Title of Presentation Presenter Presenter position @twittername Meeting/Conference title, Location, Date An XML deposit file Depositing your references
  10. 10. ` Depositing your references Three ways to include a reference in your XML 3) As text reference <citation key="2697_CR10"> <unstructured_citation>British Standard. Chemical methods- Extraction of trace elements soluble in aqua-regia. BS 7755-3.9: 1995 ISO 11466 1995</unstructured_citation> </citation> 1) As structured data <citation key="459_CR8"> <journal_title>Mon Weather Rev</journal_title> <author>GJ Holland</author> <volume>108</volume> <first_page>1212</first_page> <cYear>1980</cYear> </citation> 2) As a DOI <citation key="ref10"> <doi>10.1037/13484-000</doi> </citation>
  11. 11. `Three strategies for retrieving cited-by data 1) Periodically come and get the latest data, then update your pages 3) Come and get the data on the fly when a user has asked to see it • In all cases you make HTTP requests to get the data • In #1 and #2 you have to store the results 2) For each DOI come and get the data once, and enable alerts
  12. 12. ` Periodically get the data http://doi.crossref.org/servlet/getForwardLinks?usr=<username >&pwd=<password>&doi=<doi> &startDate=<startDate>&endDate=<endDate>&date=<single day> • The DOI would be just a prefix, in which case ‘date’ must be provided • These requests can return VERY large responses Example: http://doi.crossref.org/servlet/getForwardLinks? Usr=***&pwd=***&doi=10.1067&date=2011-05-10
  13. 13. `
  14. 14. ` Periodically get the data http://oai.crossref.org/OAIHandler?verb=ListRecords&usr=<usernam e>&pwd=<password> &set=J:<prefix>:<journalID> &from=YYYY-MM-DD&until=YYYY-MM-DD &metadataPrefix=cr_citedby • These requests can return VERY large responses Example: http://oai.crossref.org/OAIHandler?verb=ListRecords&usr=bioone&pwd=**** &set=J:10.2981:60810&metadataPrefix=cr_citedby
  15. 15. `
  16. 16. ` Get the data once, and enable alerts <?xml version = "1.0" encoding="UTF-8"?> … <body> <fl_query alert="true"> <doi>10.1053/sonc.2002.35642</doi> </fl_query> </body> </query_batch>
  17. 17. `Get the data on the fly http://doi.crossref.org/servlet/getForwardLinks?us r=<username>&pwd=<password>&doi=<doi> http://doi.crossref.org/servlet/getForwardLinks? Usr=***&pwd=***&doi=10.1067/mcp.2001.115446 Example:
