This document provides an updated vision and progress report on the Sakai VRE Demonstrator, which focuses on portals, desktop applications, and distributed services for e-Research. It discusses the Personal Learning/Research Environment (PLRE) and explores various software choices for the framework, including portal software, digital repository software, and collaborative software. The document also highlights the extension of the authentication framework and the consumption of web services within the VRE. Lastly, it mentions the Sakai demonstrator and services production server, as well as the community, evaluation, and support methodology.

Sakai VRE Demonstrator – progress July’05 Portals, Desktop Applications and Distributed Services for e-Research - Updated vision - Rob Crouchley and Rob Allan With thanks to Chuck Severance
VRE IE Requirements VLE PLREs and All That! Vision following the JISC-CETIS workshop in Oxford presented by Chuck Severance Personal Learning/Research Environment The Personal Learning/ Research Environment (PLRE) effectively adds a “productivity” layer to the VLE/VRE/IE space which unifies the look/feel/usability across the multiple sources of information
Someday the PLRE will not be just a Browser • Desktop Apps have: • Better user experience • Increased productivity • But: • More complex to build • Difficult to keep up with changing technology a. pure HTML Web page b. Web page based, but with browser enhancements c. browser extension d. dedicated desktop network client e. extensible desktop application platform f. common desktop application
E-Research Framework Choices now • Portal Software: • uPortal, GridSphere, Liferay, StringBeans, Jetspeed2, JBOSS, eXo Platform • We are evaluating these in a collaboration with Jason Novotny and will produce a technical report • JSR-168 portlets have been demonstrated to be portable between frameworks • WSRP is becoming useable • .NET not yet evaluated • Digital Repository Software: • Fedora, DSpace, Plone • Collaborative Software: • Sakai, Sharepoint, NaradaBroker, Lotus Notes, OpenOffice ? • Web Services and loose coupling are helping us to realise the vision.

WP2: So what Tools are we working with? Grid Tools • MDS LDAP Browser • Grid Proxy Manager • Grid Job Submission • Grid Job monitor • Grid FTP • InfoPortal Other Portlets • Narada Conferencing • Semantic Search Grid Markets Tools • Negociation Client • Payment Service Client Data Management Tools • SRB • OGSA-DAI Service Registry • UDDI publish/ discovery • Dynamic WSDL Interface Support Tools • Certificate Upload • Desktop FTP Sakai Collaboration Tools • Schedule • Resources • Web Content • Chat • Discussion • E-Mail New Sakai Tools • LDQ Upload • Whiteboard • CopperCore • IRC • Wiki • Audio Conferencing • Resource Search CREE InformationTools • JAFER • GetRef • HEIRPORT • Google
WP3: Sakai Demonstrator and Services Production Server: • Sakai 2.0 on IBM BladeCenter server at DL with Oracle 9i on NGS node at RAL. Moving to 2.1 with WSRP producer soon. Development: • Sakai 1.51 or 2.0 with MySQL at other sites. Dissemination and Status: • Current Web site is at http://http://www.grids.ac.uk/Sakai • List of tools and status is at http://www.grids.ac.uk/Sakai/Tools
WP4: Community, Evaluation and Support Methodology to evaluate: • Collaboration tools and Sakai work sites for sharing of resources; • Newly-developed portlet-based tools linking to an SOA; • Portlets and framework extensions linked with Sakai. Community: • GROWL; Sakai VRE; CQeSS; NWGrid Tech Board; NWGrid Ops Board; ReDRESS Steering Committee; • NGS portal; Integrative Biology, e-HTPX; • ReDRESS portal developers and users; WSRP and portal framework evaluations. (Inter)national links to GridSphere, Sakai and CREE.
