Sam,
Are you thinking command line or thinking GUI?
Definitely command line -- why I was diffident about intruding into a GUI
discussion -- but heck, the subject line is "TM for linux desktop" and the
command line is definitely part of that.
Well, I've been using linux for I think about seven years now, and
I think of it both as a desktop (like KDE) and as a command line,
so I wasn't sure what you meant.
A lot of Ceryle's
functionality is command line operable, from XML validation and
well-formedness checking, LTM and other format conversion to XTM,
etc. If you meant command line, is there something specific you
had in mind?
See the first URL above, for my KT presentation. Basically, it seems to me
that if its sensible to navigate the linux file system with its tree
nature (ok, a graph with links) its sensible to navigate a topic map with
its graph structure. One would cd to a topic, etc.
Well, "sensible" I leave to you to define. A very large or complex Topic
Map doesn't seem too sensible to navigate via command line, but perhaps
query. Some Topic Map structures are pretty complex under the rug, at
least mine are. But I think I get your point: treating it a bit like a
file system. I'll check out your presentation tomorrow -- it's getting
pretty late here.
Editing seems a bit difficult, but perhaps query if
we had a query language, etc.
Not perhaps so very hard, if we are dealing with URIs, names, and small
chunks of #PCDATA most of the time (as at least with XTM we are or -- some
would say should ;-) -- be doing. XSH makes it pretty easy to work at this
level. Not that I'd want to author a humongous topic map in the shell, of
course, but adding value to an existing map shouldn't be so hard.
Of course, there's lots of back end stuff to work out ...
Yeah. A lot so far as I can see. Having built up an application
that started on the command line (there wasn't a GUI for quite a
while), I've not spent that much time with it for months, but it
does things like:
% ceryle -l ./data/authoring.ltm -o ./out/authoring.xtm
% ceryle -l ./data/authoring.ltm -o /dev/null
(for LTM validation, as normally it'd spit it to system.out)
% ceryle -x ../../text/canasta.html (XHTML validation)
etc.
The difficulty I see in doing stuff from the command line isn't so
much the machinery behind the scenes or under the rug, it's trying
to figure out how you'd create an XUpdate-like syntax for XTM. I
think Kal has something along these lines in TM4J, and Ceryle uses
TM4J (Tolog?), so I may have more tools at my disposal that I had
thought.
Yeah, and I should be asleep. 'night...

The midrange prediction shows [global] temperatures increasing by
about 3 degrees. Under that scenario, about 1.25 million species,
or 24 percent of the terrestrial species of plants and animals,
will be extinct or on the way to extinction in 50 years. With a
rise of more than 3.6 degrees, 35 percent of species would be lost.
In Queensland, Australia, 85 percent of birds would face extinction.
In the Amazon, 87 percent of the plants would vanish.

Asked how he could boast of being an environmental advocate when
he owns five Hummers, Schwarzenegger instead took credit for the
vehicle's popularity. "Eleven years ago, I took the military
Hummer and I wanted to prove you could turn it into a civilian
Hummer... Now, as you know, it's the most popular SUV."
