+**Minutes:**
+
+* NRAO and SKAO are going to provide an exhaustive definition of visibility data format in xarray
+* They are also working on doing the same for `image formats <https://github.com/casangi/xradio/issues/497_>`_.
+* Their schema defines MSv4 dataset and datastructures, and will be used to enforce conformity with the schema
+* Basic idea is to have something similar to define the schema for the gains.
+* this is to ensure cross-compatibility between quartical/kms, ddf/pfb
+* versioning of the datastructure can allow for efficient development work
+* long discussion : do we store phase screens as a function inside the dataformat, or just the coefficient
+* all agree that it's a good idea to define gain solution files as xarrays
