 The HE domain and practices could serve as use cases for the developments of data models, such as Dataset DM, Cube DM or MANGO DM.

+\subsubsection{Mango}
+MANGO is a model (draft: \footnote{https://github.com/ivoa-std/MANGO}) that has been developed to reveal 
+and describe complex quantities that are usually distributed in query response tables.
+The use cases on which MANGO is built were collected in 2019 from different scientific fields, including HE.
+The model focuses on the case of the epoch propagation, the state description
+ and photometry. 
+ Some features of MANGO are useful for the HE domain:
+ 
+ \begin{itemize}[noitemsep,topsep=0pt,parsep=0pt,partopsep=0pt]
+     \item Hardness ratio support
+     \item Energy band description
+     \item Machine-readable description of state values
+     \item Ability to group quantities (e.g., position with detection likelihood)
+     \item MANGO instance association (e.g., source with detections)  
+\end{itemize}
