Report to the IAU on CODATA activities 2007-8

In astronomy, we are well aware of the changing nature, volume, and complexity of astronomical data. Most of us are aware that next generation instruments, with Terabyte databases, are going to present enormous challenges to the way that we process data, and our current ways of managing astronomical databases will probably no longer work. So there are a number of initiatives within the astronomical community, most notably the Virtual Observatory, which aim to address these. However, many astronomers are not aware that similar challenges are being met in other disciplines (e.g. geosciences, life sciences, etc.) and that similar solutions are being sought. As a result, astronomy has much to gain from cross-fertilisation with other disciplines.

 

CODATA, the ICSU Committee on Data for Science and Technology, is the cross-disciplinary forum in which such issues are addressed. Given the rapidly-changing nature of data and its management, it is unsurprising that CODATA is in a process of reinvigoration, and is exploring ways in which it can deliver greater value to science.

In its recently-released Draft Strategic Plan, CODATA identifies a number of ways in which this might be achieved. The plan identifies three strategic CODATA initiatives, including the Global Information Commons for Science Initiative (GICSI) , and identifies a number of ways of achieving greater engagement with the broader scientific community. It also recognises the success of existing CODATA activities such as the Data Science Journal, the Task Groups, and the biennial CODATA conferences, and proposes ways in which these might be made even more effective. CODATA has also adopted a new Mission Statement to reflect these changes.

 

In conjunction with these new initiatives, CODATA membership is growing. Australia and Ireland have just become members of CODATA, as has the International Union of Geodesy and Geophysics (IUGG).

Another important development has been the release of the Draft Report of ICSU’s Strategic Committee on Information and Data (SCID), whose members included three astronomers. Recommendations of this report include:

 

·         Support for the CODATA Strategic Plan, and a recommendation that CODATA focus on its strategic initiatives.

·         A proposed restructuring of the Federation of Astronomical and Geophysical data analysis Services (FAGS) and World Data Center system (WDC) into a new body, the World Data Services (WDS). A measure of success of this new body will be the value that it delivers to bodies such as the existing astronomical data centres and the Virtual Observatory.

·         A proposed restructuring of ICSU activities, to enable ICSU to assert a strategic leadership role on behalf of the global scientific community in relation to the policies, management and stewardship of scientific data and information, including the establishment of a new body to work closely with CODATA and WDS.

 

The next CODATA Conference will take place in Kiev, Ukraine, in October 2008. It is proposed that the conference will include a one-day session on “Astronomical Data and the Virtual Observatory” and also a meeting of FAGS and WDC representatives to discuss the establishment of the new WDS.
