  15. 15. Other? • OJS are working with Crossref on a tool to help deposit references • We hope it will be available from OJS v3.2 • At the moment, you would need to use one of the methods above or export from OJS and add your references into the XML • A full Cited-by plug in was available for earlier versions of OJS. We hope to revive it soon.
  16. 16. `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
  17. 17. ` Periodically get the data<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: Usr=***&pwd=***&doi=10.1067&date=2011-05-10

  19. 19. ` Periodically get the data<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:**** &set=J:10.2981:60810&metadataPrefix=cr_citedby

  21. 21. ` 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>
