Incentivised by open data regulations in conjunction with EU funding we started to deposit the data underlying our published work on zenodo. In the long run we would like to use a universal data format, such as nexus/hdf5. Our data are similar, but not identical to NXarpes-ones. We need some (at least one) additional tags to describe parameters of the liquid jet source. Currently we therefore tend to omit the specification of an application definition, with the idea to possibly draft a community definition tailor-fit to our experiments in the future. Your advice on how to proceed is very welcome.

For the liquid meta source I think the best way forward is to make suggestion in NXDL to the NIAC about the tags required and their documentation. Such an addition 
will probably require a NIAC vote but we can go over it and comment on it such that you may need it provisionally. 

Same thing with the application definition for your domain: make a suggestion to the NIAC. Place you suggestion in the contributed directory 
for application definitions.

I suggest sending your questions to the NIAC. Or open an issue on the definitions github. Then there is a record of this. 

I also suggest that you join one of monthly NIAC teleconferences in order to sort this out. The next one will probably be 
in the beginning of september. A date has not yet been set yet. But we can make sure that you get to know it.

Best Regards,
