Digitally managing punctuation in the editions of medieval manuscripts is one of those issues that initially looks like a minor detail, but later reveals itself as a tangled web of problems spanning from computer science (how to represent punctuation signs?) to philology (what types of signs exist?) through epistemology (is the processing of punctuation a mere technical transformation or a valuable part of the scholarship?). The aim of this paper is to address the theoretical aspects of these questions and their practical implications, providing a couple of solutions tting the paradigms and the technologies of the TEI.This paper describes how we dealt with the encoding and transformation of the punctuation in the Early New High German edition of Marco Polo's travel account. Technically, we implemented a set of general rules (as XSLT templates) plus various exceptions (as descriptive instructions in XML attributes), and applied them in an automated fashion (using XProc pipelines).
