Examples discussion…

of

current access

to

quality control

performed by creators

of

publicly available data


Refereed papers
Refereed papers discussion…

  • QC information:

  • Very thorough…potentially

  • Very un-standardized

  • Often most important (but fairly high-level)


Readme txt
README.txt discussion…

  • QC information:

  • Thorough nitty-gritty details

  • Very un-standardized

  • Close to data itself


On line data repositories
On-line data repositories discussion…

  • QC information:

  • Linking data exploration→ QC

  • Very un-standardized


Access to qc info via vo
Access to QC info via VO discussion…

  • 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
