• CIMA Based Remote Instrument and Data Access
• An Extension into the Australian e-Science
  Environment
• A collaboration between Indiana University, James
  Cook University, State University of New York
  (SUNY) at Binghamton
• and the University of Sydney.
• Ian M. Atkinson, Douglas du Boulay, Clinton
  Chee, Kenneth Chiu, Tristan King, Donald F.
  McMullen, Romain Quilici, Nigel G.D. Sim, Peter
  Turner, Mathew Wyatt.

• Goal Develop a comprehensive Web services based
  system for
• collaborative remote access to scientific
  instruments
• and their data.
• Why provide remote access?
• Maximise resource use and return on investment
• Training
• Community outreach and education

Why build a remote access system around (SOAP)
Web services? The good (in principle at least)
1. SOAP (Simple Object Access Protocol) -
firewall friendly (HTTP) 2. Machine friendly,
discoverable, scalable, extensible 3. Location,
language and language model independent 4.
Flexibility - loose coupling and re-usable
components 5. Supports distributed yet
programmatically accessible components 6. Grid
friendly The bad (in practice at
least) SOAP payload delivery can be slow.
May also be regarded as complex and cumbersome.

Why use the Common Instrument Middleware
Architecture (CIMA) model? Offers a general
and re-usable model for instrument access and
management using Web services adaptable to
different instrument settings Flexible and
extensible with modular use of plug-ins Publish-
subscribe or registration model Basis for a
standardised implementation/deployment
system Grid enablement of instruments
sensors Accessible with web service
protocols Common programmable interface
reusable code base Elegance .

• Developing JSR 168 (GridSphere) based portal and
  browser based tools for collaborative -
• remote data access and management (including
  processing)
• (ii) remote instrument monitoring
• (iii) remote instrument control
• James Cook University (JCU) group, led by Ian
  Atkinson, is developing a flexible CIMA, SRB and
  Kepler based system for data access and
  management.
• The University of Sydney group is developing
  CIMA based remote instrument control together
  with some tools for data access and processing
  that contribute to the JCU project

Indiana University CIMA Implementation

• 4 componentsInstrument Rep, My Manager, Data
  Manager Service, Portal Interface
• IR, MM, DM implemented in c, gSoap, Perl
• Storage ext3 file-system, MySQL database
• Portal jrs168 portlets, gridsphere
• Issues My Manager Portal implementations
  domain specific i.e. Crystallography vs
  oceanographic monitoring

Modifications to Data Management

• NFS and MySQL replaced with SRB and MCAT
• Moved from C and Perl to Kepler for data
  management handling
• Ability to customise data storage via a
  visual workflow system
• Highly extensible, not restricted to SRB as
  repository

Modifications to Portal

• Use of Personal Grid Library (PGL) for SRB data
  manipulation
• Ability to create metadata schema definitions for
  experimental metadata
• Stored experimental data is able to be easily
  retrieved and annotated
• Visual diagnostics for sensors (e.g. Graphs,
  Visual Indicators)
• Live CCD image analysis (experimental status)

Deployment Sites in Australia

• Initially Instrument Representatives deployed at
  JCU, USyd, UQ , Monash
• Initial intention Data Manager for all sites
  located _at_JCU with SRB storage facility
• Reality check!
• Goal Each site having their own Data Manager
  and SRB storage facility which is federated
  across sites
