• Working on Shibboleth SAKAI integration:– http://sakai-vre-demo.oucs.ox.ac.uk/portal.

• Investigating user attributes for searching:– Allows us to make educated guesses about what

kinds of things users are likely to be searching for, what kinds of tools and vocabularies they're expecting to be able to use to search.


Reading• Integrating Legacy Applications into a

Portal:– Investigated whether script-based Web

applications, such as PHP can be used in a J2EE environment,

– Investigated how PHP applications can be reused as portlets,

– Deployed and tested a number of PHP applications as portlets,

– Will add useful tools to the Sakai Demonstrator,– Report on experiences can be found at:

• http://dsg.port.ac.uk/projects/VRE/docs.php.


Reading•Bridging Technologies:

– JSR-223: • Allows Java to communicate objects with script-based
