4. Tara Murphy http://www.aus-vo.org Decadal Plan Meeting 2004 Why is the VO important? Future facilities (such as SKA) will require enormous software effort to achieve their potential Future facilities (such as SKA) will require enormous software effort to achieve their potential Funding for these facilities will have to include money for specialised software development The VO is developing expertise in the type of software and infrastructure required The VO is developing expertise in the type of software and infrastructure required

9. Tara Murphy http://www.aus-vo.org Decadal Plan Meeting 2004 However… To be more effective we need to To be more effective we need to –strengthen the identity of Aus-VO –achieve critical mass –be able to set long term goals

10. Tara Murphy http://www.aus-vo.org Decadal Plan Meeting 2004 The future of Aus-VO We see the VO as part of a larger movement towards e-science We see the VO as part of a larger movement towards e-science We want to produce great software for Australian astronomy data We want to produce great software for Australian astronomy data To be successful we need to change: To be successful we need to change: –the structure of Aus-VO –the way it is funded

11. Tara Murphy http://www.aus-vo.org Decadal Plan Meeting 2004 Conclusion Fact: the amount of astronomical data will increase massively in the next decade Fact: the amount of astronomical data will increase massively in the next decade Fact: old software techniques just won’t work any more Fact: old software techniques just won’t work any more To be competitive in this new era we have to plan for these changes now!
