Linking systems

  • Systems Overview
  • OpenURL
  • EDS
  • Symphony
  • SFX
  • SFX Menu (GetIt screen)
  • EZ Proxy

Systems Overview

  • Publisher/Database Metadata Record -> EDS -> OpenURL
  • Cataloguing Record (UA or OCLC) -> Symphony -> OpenURL
  • Publisher Metadata Record / UA Cataloguing -> Ex Libris SFX Knowledge Base -> GetIt
  • OpenURL -> GetIt

These systems are linked using the OpenURL standard.

OpenURL

Essentially a URL containing bibliographic metadata and context (e.g. referring page, etc).

NISO 239.88-2004

http://en.wikipedia.org/wiki/OpenURL

Example: http://resolver.example.edu/cgi?url_ver=Z39.88-2004&rft_val_fmt=info:ofi/fmt:kev:mtx:book&rft.isbn=0836218310& rft.btitle=The+Far+Side+Gallery+3

EDS

  • Get metadata from publishers or database vendors
  • Produces an OpenURL based on the publisher's metadata
  • Publisher metadata is sometimes wrong, but often incomplete.

Symphony

  • Direct URLs to some resources (e.g. free ejournals, catalogued databases
  • OpenURL populated from the SFX Knowledge Base
  • Automated system (sfx2sirsi)
  • Multiple OpenURLs because single consortial records

SFX

  • Gets metadata records from publishers and database vendors.
  • Subscriptions broken up into packages called "targets"
  • Because we can get an ejournal from different publishers/databases/platforms...
  • Journal titles can have multiple subscriptions
  • The subscriptions can have different platforms, and cover different date ranges
  • Takes an OpenURL and figures out which subscriptions are available

GetIt Screen (SFX Menu)

  • Presents each valid subscription, along with URL
  • The URL is *usually* directly to the article, but...
  • ... some platforms only enable linking to the journal
  • If no full-text links present:
  • Links to a catalogue record
  • Links to the ILL form
  • Aggregators pushed to the bottom

EZ Proxy

  • Most publishers use IP authentication
  • A proxy makes one IP address look like another
  • EZ Proxy checks a user's credentials, then sends them to the publisher using a special URL, and a UA IP address
  • Only kicks in when being accessed from an off-campus IP address
