 I dunno. Personally, since I need such a numbering scheme, I'm using a
 %%ID: line, on the grounds that it won't conflict with any
 accepted usages; and when I get that sorted out and it reaches my
 web-collection I'll use another such '%%' line for the 'base' collection,
 or maybe (probably) to form a URL. Such a scheme will never be more than
 one person's particular addition unless the writers of the software in use
 choose to incorporate it. Even then there's always the John Chambers
 Case - people who read ABC directly and can't even be bothered to include
 an X: line :- but we can't do anything about that :)

I think its quite clear that it is impossible to enforce whatever
numbering scheme to all abc format users, so the only question is if we
can find a solution that is based on an agreement of a large number of
abc collection owners (and programmers) an so reasonable and open that
others join it because they find the agreement sensible. 
It could be something like the identification system in librarys,
probably made up the same way (are there librarians out there ?). And
the main problem will still not be solved, that nobody can stop people
from stripping off all this usefull information when copying the source.
Besides this there is a big problem with altered files in general: If I
change the apperance of the abc text - like I do it regulary - whose
file is it then, if I correct or alter the abc text - the music - what
happens then ? 
Again we could - and should - make up a code of conduct for this cases
but there is no way of enforcing this, just the personal decision to
follow the rules for the sake of a better world ;-) . 

An unique ID has to be long: if there are collections which include
large sources (1001 tunes... or many tunes of the same kind, one needs
at least four digits to to idenify them within the file or collection,
and if there are more sources or kinds of tunes, at least three digits
for identifying them (better more). If we use letters and numbers for
identfying the place, person  or collection three digits for this
purpose will not be enough if we do not want people to use names like
7QX. So, at shortest a ID has to allow at least eleven digits and, if
we want to make these ID's to give further information (person,
collection, area ...), eleven will surely not be enough.
I opt against Zip codes or geographical names in an ID as they lose
their meaning in the same way that URL's do when the person moves.

To avoid double use there has to be a record of ID's which are in use or
had been used in the past (also this record could contain information
about the author like suporting the actuall URL; this record must be at
a save place in the net, available for a long period of time).

So, I find this idea interesting, but I think this must be discussed and
planned in long terms.

Yes.

 It could be something like the identification system in librarys,
 probably made up the same way (are there librarians out there ?).

I think the `tune/transcription ID' should be similar in spirit 
philosophically to the `message ID' found on e-mail messages and Usenet 
postings. That is, it shouldn't a priori try to `classify' the tune 
according to some set of criteria (which we will never be able to get 
a consensus on), but be merely a globally unique identifier.

My view would be that the most sensible approach for this would be using
URNs (or Uniform Resource Names), which are basically like WWW-style 
URLs but don't specify *where* a certain resource is to be found. For 
example, we could agree on a syntax like

  urn:abc-id:collection:collection-dependent-part

like, for example,

  urn:abc-id:skye-coll:miller_of_drone

There would have to be a registry for collections to ensure that the
collection names remain globally unique; of course a collection
 would not have to refer to an actual published volume of tunes, but we
could have

  urn:abc-id:campin:...

and so on, where each owner of a collection would be free to make up
their collection-dependent-parts (within the confines of URN syntax).
This could of course contain an informal classification.

The nice thing about this approach is that as URN usage becomes more
widespread there could be a `resolving service' accessible to WWW
browsers and such that would map abc-id URNs to actual URLs where the
resource (i.e., tune) could be found. Of course use of this would not be
mandatory; indeed it would not be mandatory for tunes to be actually
available on-line.

If this idea catches on we should try and get a URN namespace 
registered with the IANA.

 And
 the main problem will still not be solved, that nobody can stop people
 from stripping off all this usefull information when copying the source.

 change the apperance of the abc text - like I do it regulary - whose
 file is it then, if I correct or alter the abc text - the music - what
 happens then ? 

This is difficult to get right. There could be various transformations
of an ABC text that would change the bytes of the text but would leave
the musical contents as well as the `meta-data' (the title, composer and
so on) unchanged.

In my opinion, if somebody assigns an URN to a piece of ABC text that
means that he or she `signed off' on it as it stands, and that it should
be passed on either verbatim or without that URN. If a piece of ABC text
is changed then the URN of the `original' could be preserved in a header
line.

[abcusers] Susato's Danseryes

2001-09-03 Thread Frank Nordberg

Just like to tell everybody at abcusers that I've just posted a complete
ABC edition of Tielman Susato's Danserye at
http://www.musicaviva.com/abc/tunes/susato-tielman/susato-1551.abc
As usual this is a temporary, abcusers only URL - valid until I've had
time to add the music to the main body of the Musica Viva collection.
(*That* might take quite a while.)

Danserye is a collection of 59 or so (it's often hard to tell when one
piece ends and the next begins) dance tunes in four part settings,
published by Tielman Susato in Atwerpen 1551. It's probably the best
known source for renaissance dance music today.

My transcriptions raises a few interesting questions regarding
ABC-versions of early music. Should we add barlines? How do we disern
between original and editorial accidentals? etc. etc. etc.
Anybody's views on those question are much apreciated. So are any error
reprots, of course.
