Abstract: In addition to its catalogue collection, VizieR (Ochsenbein et al. 2000) provides access to associated data using metadata from the ObsCore Data Model. ObsCore (Tody et al. 2011) is a standard of the Virtual Observatory used to map images, spectra or time-series resources with standardized metadata. Then the resources can be queried through the VO.
Associated data such as images and spectra are usually provided in FITS format, therefore one has to make the mapping between FITS headers and ObsCore. However the heterogeneity of the FITS headers or incomplete FITS headers increase the difficulty of making this mapping. We will present statistics on the FITS header contents among the resources provided in VizieR.
A new VizieR service gives access to spectra or images. These resources are ingested with tools developed by CDS and built on the Saada engine. These services assist users to create the mapping including validation.
