https://op-musicology.epfl.ch/projects/distant-listening-corpus/work_packages/1353/

This release eliminates all warnings pertaining to BWV1011, including

encoding errors,
syntax errors and inconsistencies, and
score-label mismatches.
Also, the labels have been "moved" to the Roman numeral annotation layer using the ms3 update command, which also removes any leading periods . which are not required in that layer.
