Andrew, thanks for starting the discussion! I'm officially, the "founder"
of PG-Canada, and I know only a little more than you at this point. That's
the idea behind this dicussion list. :-)

I think we can learn a lot by comparing to PG and PGAU... mostly, what
_NOT_ to do.

Again, I concur. :o)

Between the two options you stated, I prefer the PGAFS (Project Gutenberg
Archive File System) over the PGAU idea much better.
To be honest, I'm hoping to come up with an even better idea, as I don't
really like PGAFS much either.

Yes, we will have one authorative file format - XML of some sort, and
probably UTF-16 encoding.

ONLY the XML will be considered authorative. All other formats will be
generated automatically from that XML master. This is _one_ concept that is
not really open to discussion. PG's biggest problem is format of the ebooks,
a problem we will _not_ have.
Other formats will be accepted, but only if they can be converted to the
XML format, preferably via automated means, but at worst, manually.
Naturally, we want to keep such submissions to a minimum, so it will be key
to provide tools to create the XML format (or at least a psuedo XML that we
can easily import) for people to use.

ALL changed to a text will be logged, and the proper versioning noted in
the file. We will make a backup of the master before updating it. Versions
will be in _standard_ notation: major.minor.revision
In this context, each part of the version number means:
Major: the first "release" will always be major version 1 (1.0.0);
Changing a file's primary structure (ie: fixing a missing chapter or page,
etc) will result in a major version change.
Minor: a minor version change will be done when 10 or more (approx)
changes are done at once, so long as they are not changes as noted in the
"major" definition. The minor changes would include adjusting metadata,
fixing multiple typographic errors, etc.
Revision: a revision change will be done when small corrections are made
such as fixing a broken paragraph or adjusting the indenting on a stanza of
ALL corrections to a text will be done by automated systems (ie: web
interface), so versioning will be handled by the system as well.
Additionally, a 3 character language code will ALWAYS be appended to the
version. IE: 1.0.0-eng would mean the text is the first release in English.
This means that a text with the version of 1.0.0-spa would be a direct
Spanish translation of 1.0.0-eng.

Initially, I think we should concentrate on Canadiana initially, because
it will be easier to get funding with such content, but I have no intention
of limiting it. That would be repository suicide, eh? Also, it would be nice
to get a definitive collection of digital Canadiana online -- a good
flagship project for a group called "PG of Canada". :-)
Personally, I plan to work on locating and digitizing all of Nikola
Tesla's work (ranging from 1890s to 1930s) at some point, even though he was
Croatian / American. It's of personal interest to me, and said content is
not generally available already, at least not a lot of it. Another
"flagship" project that will, hopefully, put PG Canada "on the map".

We will overlap work if ANY of the following condition are NOT met:
1) Full book scan images must be available.
2) _Legal_ copyright clearance assured and record.
3) Content is properly structured and marked up.

We will start with a fully automated system, including cataloging. The
catalog will exceed standard library catalog standards and will extend to
include any metadata we need to store. At minimum, metadata will be:
LOC call number (if available)
LOC subject heading
Dewey Decimal assignment (if available)
ISBN (if available/applicable)
Description (of original print media, IE: hardcover, dimensions, etc)
If item is from a periodical the following will be added to above list:
ISSN (if available/applicable)

Yes, we will have an official clearance system as part of the automated
system. Anyone know of a Canadian lawyer or ten who might be interested in
pro bono work for PG Canada?

I already have tentative agreements with two well-known, very permanent
places. I'll give out names when I have things more firmly worked out, but I
will say they are already familiar with PG.
I'm also working on a couple of Canadian mirrors. Any other locations that
might be interested would be good - a project like this can never have too
