This topic is under the Data model pages but also addressed in the TCG Topic page : ?? TCGTopicsUtypes
What are Utypes forUtypes are names that we can attach to a piece of metadata in order to point to the same concept expressed in a VO data model.Ex: astrometry statistical error = 0.02 arcsec
This metadata can be represented in the VO using the Characterisation data model by :
char:Spatial.Accuracy.StatError.Refval
If we associate "astrometry statistical error" with this utype, we can derive various properties like:
How can I find which Utype is relevant for my data collection
SpectralAxis.Resolution.RefVal
If you publish your data with CharacterisationDM-v1.11 , you can use the CAMEA VO Tool (http://eurovotech.org/twiki/bin/view/VOTech/CharacEditorTool) to check the Utype assignation, and verify if your description is compliant to this model.
