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.

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.

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. VLEs and MLEs)
• Portals offering information to alumni or
  potential applicants
• Portals integrating the information and financial
  systems for admin

• 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.

• Producing context sensitive links that resolve in
  a user specific fashion
• From book citation to local holdings (OPAC).
• From journal-article citation to appropriate copy
  or local document-delivery system (full text).
• Any service for which a URL can be constructed.

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)

Code to embed for searching

• bean.setHost(request.getParameter("ipAddress"))
• bean.setDataBases(request.getParameter("dbName"))
  
• bean.setPort(Integer.parseInt(request.getParameter
  ("portNumber")))
• String title request.getParameter("title").trim(
  )
• String author request.getParameter("author").tri
  m()
• bean.submitQuery(
• query.and(query.getNode("author",
  author),
• query.getNode("title",
  title)))

49
Code for listing results

• lt
• for (int n start n lt last n)
• bean.setRecordCursor(n)
• Field record bean.getCurrentRecord()
• String title record.getAllFieldData("titleOfIt
  em")
• String name record.getAllFieldData("name")
• gt
• ltligtlttitlegt, ltnamegtlt/ligt
