OptionalactorWho carried the act out. An ObjectAssumption, so an attribution
can carry the belief it rests on and the reasons for it.
OptionaldateWhen it took place.
OptionallengthHow long the act made the version's paper for a length of the
paper of the version it derives from. A re-cut for a system whose
paper runs slower comes out shorter by the ratio of the speeds,
and the alignments of the copies measure that ratio more closely
than any label states a speed (lengthRatioOf). It is stated
where the edition holds to it, as a measurement naming the copies
it used and the program that found it, so that it can serve as a
premise. A speed follows from it only together with a premise
about the speed of the other version.
OptionalprocedureThe rule followed, as a term of the vocabulary: the notes stand at their pitch, the expression is re-spelled in the other system's words.
How a version was made, where that is known and worth stating.
A roll issued for another system was re-punched by an editor of the publisher's, and that was an editorial act rather than a conversion: Lawson names Kähle as the man who corrected second masters for the green system. The rule he worked by is the procedure named here, and the version's edits carry it out, so the mechanical part of a transfer is stated once instead of being spelled out per note.
