@sarsonl I have a suggestion: Since we decided, on using the `ramsis.datamodel` classes throughout the indu/ramsis ecosystem, we could also use the `ramsis.io` module throughout more of the packages. My current use case would be to use the `ramsis.io` HYDWS serialization/deserialization code in the `sfm_models` repository to work with the hydws data. Referring to my [wiki post](https://gitlab.seismo.ethz.ch/indu/rt-ramsis/-/wikis/Repositories-Dependencies) this code would clearly go inside the `ramsis.datamodel` ecosystem. I would even suggest keeping it in the same repository as `ramsis.datamodel` but I would welcome it if we discussed this more in person!
