    • Problem and solution
      • Given (bibliographic) metadata, how does one generate relevant links for it and present them to the end-user?
      • Solution: a link generator that uses the OpenURL syntax
    • History
      • The OpenURL is based upon the SFX research work of Herbert Van de Sompel and his team (Ghent, Cornell, Los Alamos)
      • The OpenURL architecture generalizes the SFX research via an open standard to be used by interested parties
      • V-link is based upon the OpenURL
    • Version
      • NISO standarized OpenURL: ANSI/NISO Z39.88 - The OpenURL Framework for Context-Sensitive Services
      • V-link supports version 0.1, 1.0 SAP and hybrids of the OpenURL
    • What is an OpenURL
      • The OpenURL is a syntax to create web-transportable packages of metadata and/or identifiers about an information object (a book, journal, article…).
      • It is a query string with key/value pairs
    • Inbound OpenURL links
        • BASE-URL is the internet address of the OpenURL link generator e.g.: http://bib.be/vlink
        • QUERY string contains (bibliographical) metadata: e.g.: genre=book&isbn=0123456789
        • OpenURL e.g.: http://bib.be/vlink?genre=book&isbn=0123456789
      OpenURL = BASE-URL '?' QUERY
    • The OpenURL QUERY
      • By value transfer:
        • metadata about a certain object (book, journal, cd, movie…) is physically delivered to V- link
        • with the metadata V-link creates context-sensitive links
      • By reference transfer:
        • a pointer/identifier (digital object identifier, pmid, local identifiers…) to the information is delivered. V- link must resolve the pointer in order to get hold of the actual information
        • V-link fetches the record and parses the metadata
        • with the metadata V-link creates context-sensitive links
    • By Value transfer OpenURL source V-link targets OpenURL (inbound link) URLs (outbound links)   
    • By reference transfer OpenURL source V-link targets OpenURL URLs Metadata source      Fetch via OAI-PMH, Z39.50, HTTP etc. identification number metadata DOI, pmid, OAI…
    • By reference example OAI-PMH
    • marc21 xml from VubisSmart
    • Outbound database specific links
      • The metadata received via the OpenURL is used to generate deep links to V-link targets
      • The deep links are most of the time database specific URLs: e.g. ISBN link to Amazon.com (isbn=1565925777) http://www.amazon.com/exec/obidos/ASIN/1565925777/
      • Some provider do support OpenURL for outbound linking: e.g. Springer link http://www.springerlink.com/openurl.asp?genre=journal&issn=0942-8925
    • Supported genres
      • OpenURL genres:
        • biased on scholarly material
        • article, book, bookitem, conference, journal, preprint, proceeding
      • V-link genres:
        • extra private genres
        • vlink-audio, vlink-game, vlink-movie, vlink-ticker, vlink-track, vlink-unknown
    • V-link flow WebOpac (local OpenURL source) BD Book V -link (local) Menu … Amazon Amazon (external OpenURL target) Book Amazon 1 2 3
