  2. Background – JISC/DNER “Integrated access to educational resources licensed by JISC” The DNER can be thought of as having two components: • The underlying information environment: how to find, access and disseminate quality information resources. • A collection of information resources (referred to as “content”) of particular value to the research and education community. GAUG 2002. Lady Margaret Hall, Oxford University

  3. The problem - multiple services GAUG 2002. Lady Margaret Hall, Oxford University

  4. The solution – brokers & portals GAUG 2002. Lady Margaret Hall, Oxford University

  5. Components: Z39.50 Protocol Z39.50 Generic (ISO/NISO) search/retrieve protocol for information retrieval between portals and content providers GAUG 2002. Lady Margaret Hall, Oxford University

  6. Portals - Definition • “A portal is essentially a themed gateway to a number of information sources often offering additional value by processing or combining information from different sources. Portals may also offer personalisation services, allowing a user to customise the portal to their own needs, (in effect performing a similar role to the browser bookmark file).” • JISC Technology Watch Report: Java Portals. Matthew J. Dovey. December 2001.(http://www.jisc.ac.uk/techwatch/reports/index.html) GAUG 2002. Lady Margaret Hall, Oxford University

  7. Portals - Types • Types of portal include: • Subject based portals e.g. RDN • Specialised subject or topic based portals for researchers • Course based portals (e.g. VLE’s and MLE’s) • Portals offering information to alumni or potential applicants • Portals integrating the information and financial systems for admin GAUG 2002. Lady Margaret Hall, Oxford University

  8. Portals - Architecture GAUG 2002. Lady Margaret Hall, Oxford University

  9. Portals – “Content Syndication” GAUG 2002. Lady Margaret Hall, Oxford University

  10. Portal - Example GAUG 2002. Lady Margaret Hall, Oxford University

  12. Overview of JAFER • Java Access For Electronic Resources (JAFER) • JAVA + XML = portable CODE, Portable DATA. • Hides Z39.50 behind XML. AIMS • Easy to use • Visual • Open Source. Allows web developers to build tools which allow embedded content, for use by academics. GAUG 2002. Lady Margaret Hall, Oxford University

  13. Client Architecture GAUG 2002. Lady Margaret Hall, Oxford University

  19. Open URL standard: Producing context sensitive links that resolve in a user specific fashion: • From book citation to local holdings (OPAC). • From journal-article citation toappropriate copy or local document-delivery system (full text). • Any service for which a URL can be constructed. GAUG 2002. Lady Margaret Hall, Oxford University

  20. ZServlet • “ZGet” (based on version 1.0 of the servlet circa1999): • http://jafer1.las.ox.ac.uk:8080/ZGet? Author=Shakespeare&Title=Hamlet • OpenURL: • http://jafer1.las.ox.ac.uk:8080/OpenURL? • issn=1234-5678&date=1998&volume=12&issue=2 GAUG 2002. Lady Margaret Hall, Oxford University

  29. Prototype Reading List: GeoWeb GAUG 2002. Lady Margaret Hall, Oxford University

  30. Prototype Reading List: GeoWeb • For GeoWeb 4 needed to rewrite • Marcprint_Geac.fcl (which formats records into a temp file when “Mark” button is used) to include all necessary fields, in particular the LCN for doing the hyperlinks • export.pl (which sends temp file to output devices) so that temp file (marked records) are parsed differently, and to create a new output method (email html code) • mail.html to display the second input form, for this new export method • GeoWeb 5 uses Java instead of FCL and Perl, so will need to write a new java class to do the additional export method • resulting email is snippets of valid html 4.1 and css 1 • uses css (cascading stylesheets) so it is easy to integrate with visual design of your own site • marked up in named spans (“author”, “title” etc) so that styles can be assigned to any component (e.g. may wish the author in italics, or the title in red, and so forth) GAUG 2002.
