Re: [xsl] Tools to Flatten a DTD

["Eliot Kimber eliot.kimber@xxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Many, many years ago (1992 or 1993, I think), when I was at IBM and a brash
punk kid, I showed up at the SGML conference with a disk (the ones that look
like a save icon) with IBMs SGML DTD and some documents on it.

I went around to all the vendors and said Hey, can you show me what your
product will do with my SGML stuff?.

When I got to the N&F booth Ken Holman was there, smiling like he always does,
friendly and welcoming. He took my disk, popped it in his computer and said
just a minute.

I dont recall now how long it took to loadit may have been immediately or
maybe he said come back in a bitbut in any case, it did eventually load and I
got to see the amazing visualization of our crazy 800-element DTDs.

Of all the vendors there, Near and Far was the only one to successfully load
my DTDs or content.

Cheers,

E.

Near and Far is the tool I wrote about. Especially great if you have to deal

I had a look :-)

Oddly, although I mention loading a DTD from a flattened version in
Near&Far (p.173) I don't say anything about using Near&Far to do the
actual flattening. Debbie is well ahead of me here.

On p.177, the book says:

I have snipped out those pages at
http://xml.silmaril.ie/downloads/normdtd-spam.pdf<http://xml.silmaril.ie/down
loads/normdtd-spam.pdf>

The ospam binary is still shipped in the OpenSP package.

NormDTD was DOS-only
(https://nl.ijs.si/et/talks/Eurolan/silSGMLpubSWedit.html#normdtd<https://nl.
ijs.si/et/talks/Eurolan/silSGMLpubSWedit.html#normdtd>)which
presumably means it will be happy in a modern DOS emulator.

I do still have the CD-ROM is anyone wants a copy.

You will still be able to install Win95 and then install NFD in it :-)
Meanwhile there is still a small market for a good schema visualiser of
the calibre of Near&Far. Nothing currently available comes anywhere near
IMNSHO.
