  \subsection{Time series uses cases already covered by ObsCore1.1}
  Several uses-cases for time series discoveries were considered in the ObsCore 1.1 specification, built on its short list of time related features.
-They are available in appendix A section A.4. Discovering time series . 
-Here the \emph{dataproduct\_type} value is "timeseries", very general, but the same uses cases can be applied for more specific time sampled datasets like "time-cube" or or "light-curve" available now in the \bf{product-type} vocabulary .
