Direzione di ricerca

Start with the note.Note and note.Rest classes and the base object class that defines priority and sortTuple(), then check how the MusicXML and MEI parsers set element ids. Decide whether xmlID is a new string attribute or reuses priority, which the issue leaves open. Done means Note().xmlID returns None by default and the parsed id for notes and rests from an MEI or MusicXML file, with tests covering both cases.

Descrizione

enhancement

Motivation

Adding xmlID as a property would be useful to people who want to be able to go between music21 analysis and the score itself easily. This would greatly facilitate taking analysis done with music21 and encoding it into the symbolic notation file itself. This would be similar to how scores parsed in music21 have a "priority" property which is very useful when analyzing kern scores and wanting to go between music21 and the symbolic notation file easily.

Feature summary
Add xmlID as a property on objects of potentially all types, but at the very least notes and rests. Alternatively, since this only applies to xml and mei scores and those file types do not make use of the "priority" property, priority could serve double duty as the xml id property name. Though I believe priority is currently ints and xml ids would have to be strings, and xml ids can't be used in the sort order (object.sortTuple()) like priority can.

Proposed implementation
n = note.Note()
print(n.xmlID) # -> should print "None" for notes that aren't from an xml or mei file (or are but don't have the property), and the xml id string otherwise

Optionally, describe the implementation or the interface, in code or pseudocode.
