4. How it works Source Resolver Target MLA Local server JSTOR

5. Parts of the OpenURL Base URL: ? Query Origin and Object description GLOBAL-IDENTIFIER-ZONE and OBJECT-METADATA-ZONE and LOCAL-IDENTIFIER-ZONE

6. Base URL and Origin Base URL –http://ctwsfx.wesleyan.edu:9003/sfx_local/?http://ctwsfx.wesleyan.edu:9003/sfx_local/ Origin Description – sid=HWW:GSFT – sid=Ovid:PsychINFO

7. Global Identifier Zone doi : digital object identifier pmid : PubMed identifier bibcode : identifier used in Astrophysics Data System oai : identifier used in the Open Archives initiative

8. Object Metadata -- Genre Bundles –Journal: a journal, volume of a journal –Book: a book –Conference: complete proceedings of a conference Items –Article: a journal article –Preprint: a preprint –Proceeding: a conference proceeding –Bookitem: an item that is part of a book

9. Object Metadata Aulast: The first author's last name Aufirst: The first author's first name Auinit: T he first author's first and middle initials Auinit1: The first author's first initial Auinitm: T he first author's middle initials Issn: An ISSN number Eissn: An electronic ISSN number Coden: A CODEN Isbn: An ISBN number

10. Object Metadata Sici: A SICI of a journal article or volume Bici: A BICI for a section of a book Title: The title of a bundle (journal, book, etc) Stitle: The abbreviated title of a bundle Atitle: The title of an individual item Volume: The volume of a bundle Part: The part of a bundle Issue: The issue of a bundle

11. Object Metadata Spage: The start page of an individual item Epage: The end page of an individual item Pages: This field is ' spage-epage' Artnum: The number of an individual item Date: YYYY-MM-DD, YYYY-MM, YYYY Ssn: The season of publication Quarter: The quarter of publication

12. Local Identifier LOCAL-IDENTIFIER-ZONE consists of a pid (private identifier) tag-name and a corresponding tag-value pid=%3Can%3E199809103552023%3C%2 Fan%3E

13. Next Step OpenURL version 1.0 NISO standard Z39.88 Use GET or POST and use Keyed Values or XML The new standard does not: –Constrain the type of resource that can be referenced –Require or constrain responses to an OpenURL request –Constrain the purpose for which the ContextObject is transported

14. Three Ways to to send Metadata Packed-Value transport – representations of ContextObjects are delivered as values By-Reference transport – the network location of representations of ContextObjects is delivered Inline transport – representations of ContextObjects are delivered as Key/Encoded Value pairs

15. Parts of a Context Object The Referent : resource that is referenced The Referring Entity: the entity that references the Referent The Requester: the end user that is requesting the service The Service Type: the nature of services being requested of the Resolver The Resolver:the OpenURL Resolver at which the request is directed The Referrer: the site or application that is generating the request

16. Inline transport http://www.example.net/menu? url_ver = Z39.88-2003 & url_tim = 2002-03-20T08:55:12Z & url_ctx_fmt = ori:fmt:kev:mtx:ctx & rft_id = ori:doi:10.1126/science.275.5304.1320 & rft_id = ori:pmid:9036860 & rft_val_fmt = ori:fmt:kev:mtx:journal & rft.title = Science & rft.atitle = Isolation of a common receptor for coxsackie B viruses and adenoviruses 2 and 5 & rft.aulast = Bergelson & rft.auinit = J & rft.date = 1997 & rft.volume = 275 & rft.spage = 1320 & rft.epage = 1323 & rfe_id = ori:doi:10.1006/mthe.2000.0239 & rfr_id = ori:db:elsevier.com:ScienceDirect & req_id = uri:mailto:jane.doe@caltech.edu & ctx_tim = 2002-03-20T08:55:12Z & ctx_enc = UTF-8

17. Other Methods By-Reference transport http://www.example.net/menu? url_ver = Z39.88-2003 & url_tim = 2002-08-16T17:23:45Z & url_ctx_fmt = ori:fmt:kev:mtx:ctx & url_ctx_ref = uri:http://www.example.org/temp/12587.txt Packed-Value transport http://www.example.net/menu? url_ver = Z39.88-2003 & url_tim = 2002-08-16T17:23:45Z & url_ctx_fmt = ori:fmt:kev:mtx:ctx & url_ctx_val = rft_id=ori:doi:10.1126/science.275.5304.1320
