9. European Space Astronomy Centre (ESAC) Villafranca del Castillo, MADRID (SPAIN) Aurélien Stébé Registry and Curation, Oct 2005, ESAC, Spain The Curation Tests  Level 0 : a Resource entry exist Get the Resource entry from the Registry  Level 1 : the Resource is valid Validate the Resource using the VOResource schemas  Level 2 : the Service is valid Extract the Resource type and call the specific sub-method Check Resource content for minimum information

10. European Space Astronomy Centre (ESAC) Villafranca del Castillo, MADRID (SPAIN) Aurélien Stébé Registry and Curation, Oct 2005, ESAC, Spain The Curation Tests  Level 2 : SIAP specific Check the referenceURL validity Call the METADATA method and validate the result Call multiple Image Queries, both correct and bogus Download image references we got, if any  Level 3 : SIAP specific Extract the Region Coverage from the Resource Call Image Queries on all regions using random coordinates and increasing SIZE Download image references we got, if any
