Examples

of

current access

to

quality control

performed by creators

of

publicly available data


Refereed papers

Refereed papers

  • QC information:

  • Very thorough…potentially

  • Very un-standardized

  • Often most important (but fairly high-level)


Readme txt

README.txt

  • QC information:

  • Thorough nitty-gritty details

  • Very un-standardized

  • Close to data itself


On line data repositories

On-line data repositories

  • QC information:

  • Linking data exploration→ QC

  • Very un-standardized


Access to qc info via vo

Access to QC info via VO

  • Uniformize way of access (also look&feel)

  • Link from data to already available QC info wherever possible

  • Standardize only the easy standardizable (small) fraction

  • Description (“metadata) is zero order quality info

    • Description data itself

    • Description data derivation

  • 0th order Quality Control =description data+its derivation

  • Astro-WISE links description data & its derivation & its QC to the VO
