Examples

of

current access

to

quality control

performed by creators

of

publicly available data


Refereed papers

  • QC information:

  • Very thorough…potentially

  • Very un-standardized

  • Often most important (but fairly high-level)


README.txt

  • QC information:

  • Thorough nitty-gritty details

  • Very un-standardized

  • Close to data itself


On-line data repositories

  • QC information:

  • Linking data exploration→ QC

  • Very un-standardized


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


In VOExplorer/Astroscope


In Aladin

?


In VO registry

Access to QC info via VO

  • Uniformize way of access

  • Description (“metadata) is zero order quality info

    • Description data itself

    • Description data derivation


An example of public access to description of

  • DATA

  • DATA DERIVATION

  • QC


A single but federated environment to calibrate, archive and disseminate astronomical imaging

Brazil


Extreme backward chaining


Extreme backward chaining

  • Astro-WISE stores:

    • Data descriptionData derivation description

  • Publicly available for public data


Extreme backward chaining

This also publicly available for public data

…..idem for next slides

Conclusions

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

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