This work package was aimed at establishing the feasibility of making existing VRE (Grid) components available in Sakai/ CHEF. The project partners at Lancaster and Daresbury had access to a range of research tools that could be integrated into a VRE framework. We investigated the feasibility of creating an integrated suite of such tools, in order to determine whether there were any generic problems we needed to forewarned about. This work package contributed to a report (Evaluation Report 2) together with any software wrappers employed in making Grid tools available in the Sakai/ CHEF framework. These wrappers will serve as useful templates for other Grid tools.
Work was be done on the construction of a demonstrator, with a number of such tools integrated. It wass anticipated that the construction of such a demonstrator will be the optimal way to establish feasibility and get feedback from users in sample e-Science projects. This work package is closely coupled with WP 4, but we list the components here.
Work carried out includes:
|3.1||InfoPortal||Daresbury||Grid Information Services and XML metadata about projects, users, applications and resources|
|3.2||HPCPortal||Daresbury||``Active'' services for authentication, file management, data management, workspace, job submission and applications|
|3.3||CCF Whiteboard||Daresbury||Collaborative Computing Framework being deployed in the e-Minerals project from U. Reading (UK) and U. Emory (USA). Collaboration with Vassil Alexandrov (Reading)|
|3.4||SPP Cross search||Lancaster||Subject Portals Project portlet for RND resource cross searching. Collaboration with SPP project developers (Bristol, Bath, Oxford)|
Sakai is an ambitious project which already comprises a rich set of tools and templates for extending the set. Since the Denver conference, Mark Norton has taked the talk section on cloning tools and written it up into a full tutorial document . This tutorial contains step-by-step instructions on cloning an existing Sakai beta tool (sakai-module) and modifying it to be a new, stand alone tool. Whilst the example is a very simple ``Hello World'' application, it can serve as the basis for creating new Sakai tools. Chuck Severance demonstrated this by creating a MyProxy tool.
Pre-built collaboration and research tools have been described in Section 5. Sakai also has a comprehensive and growing set of VLE tools developed in the Sakai Educational Partners' Programme, see http://www.sakaiproject.org.
Discussions have indicated a number of additional tools which could (should) be developed and integrated into a Sakai-based VRE framework. We are aware that work is ongoing both in the UK, USA and elsewhere to develop appropriate open-source Java-based tools in many of these areas which could be adapted quickly. Further information about this is provided in Appendix F.
We report on progress with evaluation and development of a couple of the tools for Sakai. The outcome of these initial evaluations is promising as we are gaining increasing knoweldge of working with the CHEF framework code base. The release of Sakai 1.0.b2 on 23rd July and later RC2 enabled us to continue with Sakai and provide a fuller report on this work at the e-Science All Hands Conference in September.
