Validate exported meta data #6854
Description
Is your feature request related to a problem? Please describe.
With #6815 there is the possibility to validate imported data and internal meta data files. But there is no way to validate the exported data after the XSLT transformation and the export maybe additional files is done.
Describe the solution you'd like
It would be really nice to have the possibility to validate the exported / transformed meta data against a defined and supported schema like on import or internal meta data.
For this the exported data and used transformation file should be configurable (currently the export XSLT file must have the same name like used ruleset) in the UI and you can select in which format the resulting file should be validated f.e. METS/MODS or METS/DC or ... at least for this formats which are supported by the application validation already. Maybe in an additional later pull request there maybe must be add a way to define additional schema validation files outside the application itself which are maintained by the user itself.
Describe alternatives you've considered
You can validate the exported data after the export and transformation is done by the application but then the export task itself is in most cases closed by the application and reporting not valide processes back to the user is time consuming and complex as you must interrupt and reset the workflow of this reported process.
