Validation error

[nitrosx]

When uploading a new dataset, the client upload the files and than create a new dataset object and validate this new dataset.
If there is any issue with the newly created dataset, user will receive a validation error, after the files have been uploaded.

As a user, I would expect to receive the validation errors before any upload happens.

Good point! This needs to be fixed.

Unfortunately, this only helps with Scitacean's validation. The server might still reject the dataset. Is there a way to ask if a dataset is valid without creating it in the database?

In the new backend, we added an endpoint that validate the data model, but does not create the entry.
Unfortunately, in the old backend there is not such functionality.

Ok. For now, let's validate locally before file upload. And add remote validation when possible.
