Minor nit, you don't check the emptiness of the data repository. You just check if the meta.tsv is not there yet. I think you should either adjust the comment or change the code 😉

I’d rather adjust the code, because it wouldn’t make sense to check the data repository in this case. I agree that the comment could have been more concise. I’ll adjust this.

By accident, newly created data repositories didn’t work with the updater. The reason is that the updater checked the data schema version but failed, because no meta.tsv file (which contains the data schema version) was present. This adds a check that, if the meta.tsv file is not yet present, simply succeeds with the update, through which the data repository is populated with an up-to-date schema anyway.

By accident, newly created data repositories didn’t work with the updater. The reason is that the updater checked the data schema version but failed, because no
meta.tsvfile (which contains the data schema version) was present.This adds a check that, if the
meta.tsvfile is not yet present, simply succeeds with the update, through which the data repository is populated with an up-to-date schema anyway.In contrast to #146, this allows users to get started with an empty repository instead of having to create a
meta.tsvmanually and reading through some more documentation.Closes #145.
